PESTS Nematodes are hidden cause of many turf and plant failures Nematodes are very common and widespread and occur in large numbers on many different plants, including turf, according to Dr. Norman L. McCoy, area plant pathologist for the Texas Agricultural Extension Service, based in Dallas. "Nematodes are sometimes called eelworms, and this ex-pression, better than any other, describes their shape," Dr. McCoy told LAWN CARE IN-DUSTRY. Most of the species found associated with roots are too small to be seen when plants are examined in the field, either with the naked eye or the aid of a hand lens. Worm-like organisms frequen-tly observed on such occasions are likely to be relatives of the common earthworm and not FRIENDS OF THE EARTH PETITION Proposed EPA regulation would prohibit pesticide spraying without written permission of neighbors A proposed regulation by the federal Environmental Protec-tion Agency (EPA) would pro-hibit spraying of pesticides with-out written permission of per-sons living or owning property within 250 feet of the sprayed area's boundaries. A second part of the proposed regulation would require the permission of residents and property owners within 1,000 feet of the sprayed area's boun- daries when application was done with fine droplet misting equipment. The proposed regulation is based upon a petition submitted by the environmental group Friends of the Earth. Notification appeared in the U.S. govern-ment's Federal Register earlier this year, asking for comments from interested parties Š in- cluding the lawn care industry as a whole Š no later than April 17, 1980. The Professional Lawn Care Association of America (PLCAA) early last month suggested a letter-writing campaign by mem-bers of the industry, and also \AWN m ^ftm Jg Serving lawn maintenance Ł M^Mm^^wmm and chemical lawn | care professionals.

They are difficult to see because most of them are slender and translucent. The average length of the kinds that occur in turf is probably about one millimeter. The life cycle of most of the plant parasitic nematodes is sim- ple and direct, Dr. McCoy said. Females lay eggs that hatch into young, called larvae, and these larvae are much like adults in apperance and structure.

This projects to a total of almost 4.5 million customers serviced in 1978 by readers of the magazine, according to market research manager Clarence Arnold. The question asked on the sur-vey was: "Approximately how many accounts did your business serve in 1978 with mowing, turf maintenance, ornamental main- tenance or turf spraying ser-vices?" Answers would reflect total number of customers of both chemical lawn care and mowing/maintenance com- panies, and also the large num-ber of companies in the industry that handle both. According to Arnold, 89 per-cent of these accounts are under contacted the EPA directly on behalf of the industry, according to PLCAA executive director Glenn W. Bostrom. The largest part of the pro-posed regulations dealt with aerial application of pesticides. Also due to possible spray drift, the proposal would prohibit aerial pesticide applications without written permission of residents and property owners within 1,000 feet of the sprayed area's boundaries. According to Bostrom, the suggested letter PLCAA recom-mended its members send to the EPA read: "We note that the Friends of the Earth are requesting that pes- ticide applicators using ground spray equipment be required to have written permission allow-ing for possible spray drift from residents or property owners within 250 feet of the sprayed area's boundaries. In the case of mist-blow sprayers or aerial ap- plications (FAA Docket No. 19488) they are seeking a 1,000-foot buffer. "Implied but not stated in thei request is that they are seeking 'zero' tolerance for drift, eithe to page Z a contract which calls for more than one visit. Also, 91 percent of these accounts are residential. These figures imply that 7.1 per-cent of single-family, owner- occupied homes are served by the readers of LAWN CARE IN- DUSTRY, based on the federal government's Current Housing Reports, published by the Bureau of Census. The survey was conducted in July and August of last year. Results are based on a 47.4 per-cent return of the original 500 contacts responding, according to Arnold. Although the question was not asked in the most recent survey, based on the magazine's 1978 survey of its readership, chemical lawn care companies said they had an average of 937 accounts on the books in 1977, and mowing/maintenance com-panies said they had an average of 170 accounts. Approximately how many accounts did your business serve in 1978 with mowing, turf maintenance, ornamental maintenance or turf spraying services?

Scott & Sons, Marysville, Ohio said that 30 percent of homeowners say they will spend more of their time at home this year. The survey was con-ducted by Home Testing Institute. When all respondents were asked which activities they would be spending more time on this year, the following three were cited by more than a third of the people: In-terior decoration or home improvement; exterior painting or refurbishing; and lawn care and gardening. Tops among the activities cited by those intending to spend more time around their houses were lawn care and gardening Š mentioned by two-thirds of the family heads, and over half of them plan to spend more money this year on their lawns. When asked, "Do you think improvements to your lawn will add dollar value to your home or make no difference?" three-fifths thought that such improvements would increase the cash value of their homes. An earlier independent survey among realtors tended to confirm homeowners' views on the subject. In the realtors' view, an attractive lawn with flowers, shrubs and trees would add about six percent to the market value of a house Š a handsome $4,500 on a $75,000 home Š and would speed up its sale. Outdoor advertising grows: Outdoor advertising, a medium being discovered by lawn care companies across the com-pany in growing numbers, is regaining popularity, growing 10 percent a year since 1969. McCann-Erickson, Inc., an ad agency, estimates 1979 spending on billboards at $535 mil-lion, up 15 percent from 1978, but still only one percent of total U.S. ad outlays. Barefoot pumps dry over liquid: In a full-page ad in at least one midwestern daily newspaper, Barefoot Grass Lawn Ser-vice, Worthington, Ohio recently stated "11 reasons why you should consider trading your liquid lawn service for Bare-foot Grass dry lawn service." The 11 reasons trumpeted dry over liquid in headlines with explanatory copy and some pictures. The headlines were: "Barefoot dry works at the grassroots to grow your grass thicker." "Barefoot dry tailors the treatment individually. With most wets, it's one for all and all for one." "Barefoot dry works overtime. Most wets leave early." "Barefoot dry weedkillers are precise. Wets blanket everything, need it or not." "Barefoot dry insecticide sticks around when wet breaks down." "Barefoot dry stimulates healthy growth. Wet drives grass wild." "Barefoot dry won't give your lawn ugly, brown sunburn." "Barefoot dry works low. Wet stays high Š and gets mowed away." "Barefoot dry prevents disease. Wet offers a stopgap." "Great Scotts. It's Barefoot dry." "The Barefoot guarantee." The reference to "Great Scotts" said that Barefoot uses Scotts fertilizer. Letters: We get some nice letters here at LAWN CARE IN-DUSTRY, and we'd like to share some of them with you. William Vogel, manager of Vogel's Spring Valley Turf Care Products, Jackson, Wis., writes: "I would like to take this opportunity to commend you on the good job you are doing to inform an unify the turf care in-dustry through the informative and thought-provoking arti- cles in your magazine. While attending the Illinois Turf Con-ference, I had the pleasure of meeting you at your booth. "Three years ago here at Vogel's Seed & Fertilizer, Inc., we started a new division called Vogel's Spring Valley Turf Care Products. We handle fertilizers (both liquid and dry), chemicals, seed and liquid equipment. "Recently we sponsored our first (and hopefully annual) 'Milwaukee Turf Day'. We have representatives from Allied Chemical, Ashland Chemical, Monsanto and Snyder In-dustries tank manufacturers talk about their products, and a talk on turf disease. Despite an eight-inch snowfall the day of the meeting, we had a fine turnout. "I thought I'd drop you this line to let you know that the Milwaukee turf care market, although young compared to some others, is alive and trying out its new legs. Again keep up the good work. I especially enjoy articles on comparing fertilizer and chemicals and statistics on purchases." And Bill Lyons of Canal Fulton, Ohio writes: "I congratulate you for publishing the article by C.R. Staib and Dr. J.T. Hays of Hercules for writing the splendid article 'Fertilizer Basics' (LAWN CARE INDUSTRY, February, 1980). I do hope they plan to publish this in a small booklet form. It will be just as good for the unborn future turf managers as all in the field today. As inflation goes, so goes the price of all fertilizers; so the last paragraph would have to be done on a chart basis to be flexible to future costs."

HERBICIDES < oc E-1 c/3 D D g u < U z < TOOLS,TIPS & TECHNIQUES Research new products on home lawns Philip Catron, regional agronomist for ChemLawn Corp., Westminster, Md., suggests that lawn care operators test products on home plots before incorporating them into their regular program. And the best way to determine the relative effectiveness of a product in a particular region of the coun-try is to test it on a customer's lawn. "University research is excellent," he said, "but it's not home care research. Get the permission of a customer and give him a free application for a year if he lets you use his lawn as a test lawn to see how a product reacts." Catron, speaking at the Pennsylvania Turfgrass Con-ference in Hershey, Pa., said before incorporating a product into a lawn care program operators should secure as much in-formation about that product as possible. Controlling broadleaf weeds When it comes to controlling broadleaf and viney weeds, her-bicides are the answer, accord-ing to Dr. William H. Daniel of Purdue University. Here are some of his tips. Always use the lightest possi-ble rate of application for herbi-cides. Don't overuse the chemicals just because the turf can tolerate higher amounts. Timing. Treat lawns any time weeds are growing. For many lawns, however, mid-fall is the best time to kill weeds, clover, etc. Since weeds germinate in the spring, summer and early fall, selective kill in September and October will assure a clean lawn for your customer next spring. This also favors desirable grasses, as they can fill in for maximum turf cover next year.

DOW DOW CHEMICAL U.S.A. *Trademark of The Dow Chemical Company The poorest time to treat is late spring, because it opens up the turf to crabgrass, new weeds, etc., thus repeating the weed cy-cle. Fall treatments also minimize potential damage to tomato plants, gardens and shrubs. For best results, use herbicides when temperatures are above 50 degrees F. and soil moisture is adequate for plant growth. Avoid windy or hot days, which favor droplet drift and vapor move-ment. There should be ample leaf surface present, as when the turf needs mowing. This en-courages better uptake of the chemical. It takes about two to four weeks for a complete weed kill. Delay spraying of new lawns until they have been mowed twice Š more than 30 days of growth, allowing grass seedlings to become tolerant of the chemical. Application. For liquids and wettable powders, dilute with ample water, about one to three gallons for each 1,000 square feet. Apply at a low pressure, perhaps 20 pounds per square inch. Dry, granular chemicals per-mit use of a spreader and dual weed-and-feed programs. For controlling broadleaf weeds, use herbicides when tem-peratures are above 50 degrees Fahrenheit and soil moisture is ade-quate for proper plant growth. Avoid windy or or hot days. Generally, you'll need to use more chemical in the dry form, and this form depends upon dew or leaf dampness to dissolve and distribute the herbicide. Often, for convenience, several chemicals are formulated together to assure control of numerous weeds. Further, synergistic chemicals acting together permit a lighter application. Most used. The most widely used chemicals include the fol-lowing: 2,4-D will kill most broadleaf tap rooted weeds including dan-delions, buckhorn, plantain, bull thistle, shepherd's purse, yellow rocket and curled dock. Stan-dard usage is one pound active ingredient per acre. MCPP works best on viney weeds including clover, chick- weed, oxeye daisy. It augments 2,4-D very well, and is often blended about equal parts with 2,4-D. Standard usage is about one pound active ingredient per acre. Dicamba is excellent for knot-weed, chickweed, wild onion, yarrow, red sorrel, speedwell, clover, ground ivy and henbit. Its standard usage is light Š only one-quarter active ingredient per acre.

Guzman-Harty, who was born and raised in the Philippines, received her undergraduate degree in chemistry from the University of the Philippines. In 1970, she completed advanced studies in chemistry at Ohio State University and then worked at the University of Michigan's Department of Medicinal Chemistry on cancer and contraceptive research. Two years later, she worked as an assistant editor at Chemical Abstracts Service in Columbus, Ohio, and then in 1974, decided to finish her doctorate of philosophy in medical pharmacology at Ohio State, studying the effcts of tran-quilizers on the nervous system. After joining P & G, she worked primarily in the analysis and safety evaluation of different chemical formulations that are either applied to the mouth, skin or scalp but may be accidentally ingested or inhaled. She also provided safety data to an interacted with the regulatory groups prior to submission of any product for human testing. According to Jeff McKenney, general manager of CLC Labs, she will have multiple respon-sibilities which include the supervision of the lab's extensive cholinesterase monitoring pro-grams. These programs, initiated by CLC Labs for the safety of ChemLawn's employes who han-dle organophosphate insecti-cides, have continued to grow and expand due to the increased concern by other professional lawn care companies about their employes' welfare. Also, Guzman-Hardy's experi-ence includes chromatography, used extensively by CLC Labs for the analysis of pesticide formula-tions and residues. In relation to this, McKenney said, and due to the increasing demand to es-tablish the margin of safety of different chemicals in the en- vironment, she will be involved with evaluating the impact of new pesticide and herbicide for- mulations on the health of ChemLawn employes and customers as well as the customers' pets. She will regularly attend meetings and discuss current research with toxocologists, chemists, physi-cians, veterinarians and with ChemLawn regional agrono-mists. Since beginning her job with CLC in December, she has already taken major steps to answer many of the lawn care in-dustry's questions involving materials, pesticides, safety and the environment.Šby Alice Wagner Finally, An Aid For Teaching Turf grass Superintendents.

OH 44102 If I I kTI I U Lawn Care A Digest of Valuable Management Information from TUCO, Division of The Upjohn Company Lawn Insect, Disease Management Requires Knowledge and Experience Just a few years ago. most home lawns received little more attention than a systematic mowing Unlike golf course superintendents, whose jobs depend on efficient and effective turf care, homeowners were relatively unfamiliar with lawn-destroying pests But that situ- ation has changed There is steadily increasing interest in improved home lawn care Homeowners have become interested in cultivating healthy lawns for aesthetic reasonsŠto keep their yard as attractive as the rest of their residential property Good looking lawns also provide economic benefits. One recent study found that general lawn condition can change a home's value by as much as to 4%! To keep yards in top shape, lawn care people must be able to recognize damaged areas in the lawn and associate the damage to the disease or insect causing the problem. This can be difficult, since insect damage is often similar to damage caused by disease or other factors Some Problem Insect« Sod webworms, cutworms, armyworms and white grubs are among the many pests that have the ability to turn a beautiful lawn into troubled turf. To deal with these pests, the lawn care specialist must be able to recognize the insects, identify the damage they cause, know life cycles and seasonal development patterns, and know how and when to control them. Sod webworms. cutworms and armyworms are the larval stages of various moths These insects go through four stages of developmentŠegg. larva, pupa and moth Current insecticide applications are only effective on the larvae and the moth. For best results, plan insecticide applications for the larval stage, usually about two weeks after peak moth flight. Sod Webworms The sod webworm has a short, thick body, usually spotted and coarsely haired, and ranges from 1/4 to 3/4 of an inch long The larvae start feeding on grass as soon as they hatch, building burrows close to the soil surface Webworms can restrict water movement into the soil by reinforcing their tunnels with chewed pieces of grass and soil They cut off grass at the soil line, chew freely on new growth and eliminate chances for grass to grow back Damage is indicated by irregular brown spots on the lawn. Silky webs often appear in areas inhabited by the larvae Webworm moths can be identified by their pale brown or greyish brown color and their quick, jerky movements as they fly randomly over a lawn Cutworms There are many cutworm species affecting various plants, but several species make grass their major target. Sod Webworm Cutworm The glassy cutworm, which is strictly subterranean, has a greenish-white body and reddish head As its name implies, the worm has a "glassy'' appearance Tuco publishes lawn care management report A new management report on lawn care, including suggestions on control of insect and fungi pests, has been published by TUCO Agricultural Chemicals, Division of The Upjohn Company. The report offers information on insect and fungi control and ways to identify these pests. It also includes management suggestions for lawn care operators on maintaining proper soil pH levels for healthy lawns and the need to control thatch buildup in order to get maximum benefit from insec-ticides.

Because of uptake efficiency through foliage and root systems, FORMOLENE fertilizer provides the econ-omy you need with the color response and healthy turf your customers like to see. And it can be used on any kind of turf as part of your year-round lawn care spray program. In spring, FORMOLENE nitrogen fertilizer quickly greens turf, but without that burst of growth that leads to disease and excessive mowing schedules. During the hot, dry summer, FORMOLENE nitrogen won't burn when used as directed, but delivers steady growth with adequate watering while retaining healthy turf color. For fall lawn care programs, you can count on FORMOLENE fertilizer to help strengthen root formation and support winter carryover of nitrogen for a healthy growth start the following spring. FORMOLENE fertilizer has a 30-0-2 analysis and blends easily with other solution nutrients and most turf herbicides, insecticides and fungicides. It can be used at rates as high as 2 lb per 1,000 sq. ft., per application, without burning. And rates of less than 1 lb per 1,000 sq. ft. can yield excellent results, providing an edge in economy and efficiency over many nitrogen sources. This easy-to-handle nitrogen fertilizer is available from Ashland in 20-ton tank truck loads. Smaller quantities, and complete N-P-K blend concentrates based on FORMOLENE, are available from authorized dealers. In short, FORMOLENE fertilizer provides the ideal basis for putting nitrogen on your cus-tomers' lawns with a minimum of aggravation. We'll be glad to tell you more.

Some nematodes, like the root-knot, undergo the first molt before hatching, while the larva is still within the eggshell. Feeding. Some nematodes feed on stems and leaves but a much larger number feed in or on the roots and other structures that grow below ground. All plant parasitic nematodes have a stylet, a spear-like structure used for piercing and extracting cell contents. Free-living nematodes are those that are beneficial, they feed on microorganisms in the soil and do not have stylets. Plant nematodes begin their feeding operation by injecting through the stylet into the plant a secretion, sometimes called saliva, that contains, presumably, a digestive enzyme. For some species of nematodes such as the root-knot, this secre-tion has a special function of modifying the plant's cells, caus- ing them to form tissue on which the nematode can feed. In other words, it stimulates the formation of nurse cells or galls without which the parasite would die of starvation. This secretion by the stubby-root nematode when feeding on the root tips, suppresses the cell divi-sion of the roots and prevents root elongation. Stunted growth. The presence of nematodes are most obviously recognized by stunted growth, an off-color and turf thinning-out, Dr. McCoy said. If root-knot nematodes are present, one may examine the root system and find small knots occuring on the roots with a very limited root system. Soil can also be examined by a state or federal laboratory to determine the presence of nematodes. Information regarding soil sampling for nematode detection may be ob- tained from a local extension agent. "Controlling nematodes with heat is one of the oldest methods used for killing nematodes," Dr. McCoy said. "Heat has been used in two ways, heat treatment of the soil, in which small quanti-ties of soil can be heated enough to kill nematodes by spreading soil in thin layers and placing it in conventional ovens or a micro-wave oven. When treated in larger quantities, compost soil or potting soil can be put in sacks and placed in a chamber or autoclave and subjected to about 15 pounds of live steam for 30 minutes or longer. The exact time depends on the bulk of the soil. Hot water treatment is a method for killing nematodes in plant structures by submerging them for a short period in hot water. This method has been used very extensively and successfully for controlling the stem nematode in narcissus and certain other bulbous plants. Hot water treatment is best-adapted to denematizing bulbs, corms, tubers and fleshy roots while they are in a dormant condition. This treatment may also be used for some kinds of infected nurs-ery stock, but fiberous-rooted plants are less tolerant and for this reason the method has met with less favorable success among growers. Many of our nematode pests can be controlled by depriving them of plants on which to feed. Plants that have been damaged by root-infecting nematodes of any kind should not be allowed to stand in the landscape for a long time after their beauty has disappeared. They should be destroyed immediately, preferably by exposing the roots to the drying action of the wind and sun. Keeping soil tilled and exposing it to hot sun during the summer will also lower nematode populations. Chemical control of nematodes can also be used in certain situa-tions. Methyl bromide is a soil fumigant that can be used in flower beds, seeding beds, soil flats, vegetable gardens and potting soil. V a p a m and Nemacur are liquid nematicides that can be used on certain plants.

NO BUILD-UP How persistent are herbicides in soils Evidence is lacking to support claims heard from time-to-time that the potential build-up or persistence of herbicides in the soil can contaminate our en- vironment. Except in the case of overuse or gross misapplication, the degradation processes men-tioned below will break herbi-cides down into safe or non-toxic compounds, according to Ronald L. Ritter, Maryland extension weed control specialist. Biological decomposition in-volves the detoxification of her-bicides by plants and soil micro-organisms. Plants and microor-ganisms can absorb herbicides. They can store herbicides or give them off in their original form. Usually they are changed, with the breakdown products being used by the plant or organism or being discharged back into the soil solution. Chemical decomposition in-volves a variety of of chemical reactions that change the herbi-cide. Normally, the decomposi-tion products are non-toxic sub-stances that are further degraded to components that are already present in soils and plants. Act D (Decomposition) in-volves the breakdown of herbi- cides by sunlight. Whenever a herbicide is applied to the soil surface or to plant foliage it is subject to decomposition by sunlight. A number of transfer pro-cesses are important to the fate of herbicides in the environ-ment, Ritter wrote in a recent University of Maryland newsletter, The Agronomist. Herbicides can be absorbed and exudated by plants and animals. Thus herbicides can either penetrate through tissues into an organism (known as ab-sorption) or be discharged from inside an organism to the outside environment (known as exuda-tion). Herbicides that are applied to the soil surface may become -dissolved or suspended in rain water resulting in surface ru,n-off during periods of heavy rainfall. Severe run-off can also carry soil particles that have herbicides adsorbed on them. 11 Z n > x tn Z a c CD H X > 12 SEED Renovating lawns through overseeding < >« oc H c/3 D D 2 w oc < u 2 < by Larry Vetter, Northrup King Co., Minneapolis Over the past few years, the lawn care industry has had many improved turf varieties available to it. This, coupled with rapidly advancing technology, has given us the opportunity to provide top-quality turf in a wide range of situations and geographic areas. Healthy grass plants have the ability to increase in density and produce good lawns. However, when management practices, soil or weather conditions are un-satisfactory or grasses being used are poorly adapted for your situation, lawns will not be top quality. The first thing to do when faced with such a situation, and unfortunately it is a step that is very easily overlooked, is to determine why renovation is necessary. In other words, why Seed-to-soil contact is absolutely essential for proper seed estab-lishment and germina-tion. Therefore, ex-cessive thatch should be removed before overseeding. did the turf thin out, and do whatever is necessary to correct that problem or problems. In other words, what caused the problem in the first place? A good checklist to go through in determing what these prob-lems might be is: Compaction. Even the best turf varieties will not maintain vigorous growth if the soil is so compacted that there is not proper water movement or air spaces in the soil. If this is deter-mined to be a problem, some means of relieving the compac-tion are necessary before spending your customer's money on renovation. Normally, this is best accomplished mechanically with the specific method being determined by the degree of compaction that exists in the soil. Lack of light or poor air cir-culation. These two problems many times will go hand-in-hand and generally would be the result of severe tree competition with the turf area. To correct this problem, trees may have to be removed or at least a general thinning of the existing trees must be made. There are some varieties on the market today that will do well under more heavily shaded conditions, but, in general, grass plants need ade- quate light and good air circula-tion to provide a quality turf. Lack of water or poor quality water. To correct this problem, it may be necessary to install a more adequate irrigation system or instruct the customer on proper methods, frequencies and amounts of watering necessary for their lawn. In more severe cases, it might be necessary to find an alternative water supply. However, whichever one of these water problems is deter-mined to be the cause of the in-ferior turf, you should keep in mind that certain varieties on the market will provide improved quality with less amounts of water than others, and certain species will do better with different pH ranges. Excessive thatch. This can be a severe problem on older lawns that have not been properly maintained in the past. If the amount of thatch is restricting water infiltration, it will prob- ably be adversely affecting other factors which are neces-sary to have a quality lawn, and, consequently must be removed. Improper pH. Most grass plants do best under slightly acid conditions. However, there is a fair degree of variation within the tolerance of the different species. Consequently, if this is determined to be a major prob-lem, it should be corrected or the varieties should be selected that will thrive under the existing pH range. For example, "Fults" Puccinellia distans is a new release by Northrup King that thrives in high pH conditions and, consequently, has a definite role to play where high pH soils or water are a problem. Poor drainage. This, in many instances, is the key to turfgrass management. Without proper drainage, there really is very lit-tle that can be done to improve turf quality. All grass needs air available to it in the root zone, and without that, quality turf cannot be maintained. Poor nutrition. This is very un-likely to be the case in the situa-tion a lawn care businessman faces, but I include this point to remind the lawn care busi-nessman that certain grasses will do better at different nutrient levels. In other words, some grasses need more fertilizer than others, and vice-versa. With the improved varieties that are now available on the market, you can make a choice of what to plant by determining what the level of nutrition will be in the mainte-nance program for that turf. Weed infestation. Most experts will agree that weeds are not the cause of a bad lawn, but they are, instead, the result of a bad lawn. The 2-Step TUif Renewal Plan with Roundup and Pennfine. One. Wo. Spray Roundup® on the turf area to be renewed. With just one application of Roundup® herbicide by Monsanto, you can control or destroy most unwanted vegetation. Including stubborn intruders like annual bluegrass, bermudagrass, quackgrass, johnsongrass, tall fescue, and kikuyu grass. In a matter of days, Roundup circulates throughout these weeds. Even into the below-ground roots, destroying the entire plant. Yet Roundup has no residual soil activity. That means there is no injury to new seedings planted after application. Spread Pennfine Perennial Ryegrass seed over the area treated with Roundup. After applying Roundup, seed with fast-growing, fine-leafed Pennfine Perennial Ryegrass. Pennfine was developed by Dr. Joe Duich at Pennsyl-vania State University. Pennfine has been proven to germinate quicker, grow denser, and resist disease better than traditional ryegrasses. And it penetrates compact soil, sending its roots to depths of 12 to 18 inches. These qualities make Pennfine an excellent choice for turf renewal and help to explain why it's used by turf profes-sionals from coast to coast. In a short time, you'll see the proof for yourself.

A general rule of thumb concerning renovation is if 50 percent or more of the soil is bare or covered with weeds, it is best to start over. Con-versely, if 50 percent or more is covered by healthy turfgrass, chances are that total renova-tion will not be necessary and a good lawn can be provided by overseeding the poor areas. Consequently, if there is a severe weed infestation, chances are that one or more of the potential problems in this checklist are causing the weed problem. A certain amount of herbicide weed control in most turf areas is necessary from time to time, so we can't totally disregard the need for attention to weed prob- lems. However, keep in mind that if severe weed problems ex-ist, there are probably other problems that are causing this one. Improper mowing. Most of the older varieties that exist in es-tablished lawns do not do well under mowing of less than one-and-one-half inches. Also, mow- ing too infrequently, thus causing severe shock to the grass plant when it is mowed, will even-tually cause severe problems. A good rule of thumb to follow is to mow frequently enough so that no more than. one-third of the leaf area of the plant is removed at any one mowing. The variety composition of the turf stand will dictate what the proper mowing height should be. Unadapted grasses. We are all aware of the climatic adaptation of the various turfgrasses, mean-ing warm-season versus cool-season, but keep in mind that the adaptability also varies with pH, desired mowing height, amount of shade, nutrient levels, water availability, etc. With the newer improved varieties that are available to you, you can make some very positive choices when seeding that will result in quality conditions in a wide variety of situations. After you have determined what problems exist and have taken steps to correct those prob-lems, the next decision would be whether to overseed into the ex-isting turf or start over from scratch.

However, in general, late sum- Ł< mer to early fall is the ideal time for seed establishment. Dormant seeding is another option that is available to you, and this in-volves planting the seed immedi-ately before the soil freezes so that no germination will occur g during that season but will take place as soon as conditions are proper in the spring. A successful spring seeding can also be accomplished, but this should be timed so that the soil is dry enough in the spring to avoid undue compaction prob- lems when working the soil, and also to provide a satisfactory seedbed. Actually, seed can be established anytime during the growing season, it is just more difficult at certain times than others. Regardless of the degree of renovation that is necessary for the lawn, there are certain steps that need to be followed in order to provide a satisfactory turf for your customer: Ł Correcting existing problems. This refers to the items discussed earlier. Ł Remove thatch. If this was determined to be a problem, keep in mind that one of the ab-solute essentials in seed estab-lishment is good seed-to-soil con-tact. Proper germination and es- tablishment cannot take place unless the seed is actually in con-tact with the soil. This is best done mechanically if a large area is involved and can be easily accomplished with a hand rake for small areas in the lawn. Ł Mow the exitsing grass as short as possible and remove the clippings from the lawn. This will reduce competition from the existing grass plants, allow light to contact the soil, and give the new seedlings a much better chance of becoming successfully established. Ł Loosen the soil surface. Again, on a larger area, this is most efficiently done mechani- cally. However, it can be done by hand if only relatively small spots are involved. A mechanical rake set to cut grooves one- quarter inch into the soil will enhance the environment for germination tremendously. It might also be beneficial to apply a starter fertilizer at this time. Ł Distribute seed uniformly. Obviously, if there are some spots or strips that are missed, the resulting turf stand will not be satisfactory to your customer. Ł Cover the seed lightly. This can be accomplished by a light raking, a topdressing, or by run-ning a mechanical rake at right angles to the direction of the original grooves that were made in seedbed preparation. Of course, if you are using one of the mechanical seeders, this step is not necessary because the machine has already done this for you. Whatever the method that you use, this will better in-lo page 14 14 OVERSEEDING from page 13 Š sure seed-to-soil contact, which o is absolutely essential to the seed | establishment. Ł Organic mulch. This can be very beneficial in insuring a good turf stand. However, in many areas of the country, it is very difficult to get a satisfactory mulch that will not further com-pound your problems. One of the primary things that you need to be aware of, if you are planning on using a mulch, is that this can be an excellent source of weed seeds. Consequently, it is critical to know the source of the mulch that is to be used and the quality of it. Ł Roll lightly if necessary. If the surface is extremely loose or you question whether you have good seed-to-soil contact, a light < S ^ DC H co D Q Z DJ PC < u z £ < rolling would be beneficial to firm the surface of the soil and/or establish effective seed-to-soil contact. Ł Keep seed moist. Once a seed has begun the germination process, it is critical that it is not allowed to dry out. This does not mean, however, that heavy waterings are necessary since this can cause severe erosion problems, among other things. Small amounts of water or light waterings frequently throughout the day are the ideal situation for the germination process. Remember to water on the basis of the slowest germinating species being used. Ł Continue short mowing. If you have overseeded into an ex-isting turf, keep the established grass cut very short in order to Before selecting a particular variety of seed for overseeding a number of factors must be con-sidered including: What geographic area of the id what typ will it be planted on? How will the turf be used country will the seed be used and what type of soil and maintained once it is established? These are questions which must be answered to successfully establish a healthy turfgrass stand. ŁŁŁŁŁŁŁŁŁŁŁŁŁŁŁŁ eliminate competition with new seedlings. Ł Normal maintenance after two or three mowings. Once the new seedlings have matured to the point where they have been mowed two or three times, nor-mal management should begin.

At this point, you are now into fairly normal management and your programs should be adjusted ac-cordingly. We have been discussing management and establishment techniques, but in order to get the maximum benefit and thus have the happiest customer as the result of your efforts, a pri-mary consideration must be what type of seed to use. The first con-sideration and the most obvious one, of course, is where is it? This means, the geographic area of the country where the seed is to be planted, and what type of soil it will be planted on. There is the obvious warm-season versus cool-season turf-grasses that we mentioned earlier, but there also is a con-sideration that certain types of grasses will do better on different types of soils. Different grasses also react differently to different disease organisms, different insect problems, and different watering practices. The second consideration that is extremely important is how will the turf be used once it is es-tablished? There is a very wide variation in the tolerance of traf-fic, for example, between the different turf species. If the lawn is going to be the neighborhood playground, you would definitely not want to use the fine fescues and some of the common bluegrasses. In a situa-tion where traffic is a prime con-sideration, you should rely heavily on the new improved ryegrasses and some of the more traffic-tolerant improved blue-grasses. On the other hand, if the homeowner is going to maintain his lawn as a showplace that is to be looked at and admired, other varieties and species would then be appropriate. A third consideration and possibly the most variable, is how will it be maintained once it is established. Will the lawn be mowed regularly? Will it be watered sparingly or heavily? Will it be fertilized with several pounds of nitrogen per year or with only one application at best? Does the homeowner want a certain mowing height? All of these things and others will be factors in your decision of what kind of seed to plant. As was mentioned earlier, with the num-ber of improved varieties that are available on the market to- day, many of which have certain strong points inherent to them, formulations can be made to in-sure a happy customer under a very wide range of conditions.

When Charles Craig decided to renovate 35 acres of this college campus with Roundup^ herbicide in 1977, he knew that if it didn't work, he'd probably have to "hide under a rock'.' But, fortunately, Charles didn't have to go into hiding because just 7 days after he applied Roundup he was able to reseed right into the dying grasses. "Yes, I put my career on the line, but I felt all along that Roundup was going to work',' Charles says. "There was no doubt in my mind'.' As horticulturist for Mercer County Community College in Trenton, New Jersey, Charles Craig depended on Roundup for the broad spectrum control he needed for tough grasses like quackgrass, orchardgrass, tall fescue and others. And since Roundup has no residual soil activity, he was able to reseed in a matter of days. "Seed germination was ter-rific, especially with the weather we had',' Charles told us. "Every-one always says it looks nice'.' Charles still uses Roundup for touch up jobs around cracks in the pavement, park-ing lots, buildings, tree bases and flower beds. Taking pre-cautions against spray drift, Charles has no fear of harming surrounding vegetation with Roundup.

RI-8014D Write 128 on free information card 16 TURF OVERVIEW >-< S >-DC H C/3 D O 2 w oc < u 2 < Earthworm activity in turf aids in thatch decomposition by Dr. Keith Karnok, assistant professor, Ohio State University Thatch continues to be a perplex-ing problem to turfgrass man-agers. However, during the past several years research has aided in our understanding of the causes and control of turfgrass thatch. For example, low soil pH, elevated mowing height, poorly drained soils and excessive use of certain pesticides are all fac-tors which may encourage exces-sive thatch accumulation. Like-wise, research has also docu-mented the effectiveness of vari-ous thatch controlling methods such as mechanical dethatching, coring, aerification, top-dressing and liming. Although significant progress has been made in the above areas, many other factors related to the causes and control of thatch have been virtually unex-plored. One such factor of partic- ular significance is the influence of earthworms on thatch degrad-ation. Although a few popular ar-ticles in recent years have eluded to the importance of an active earthworm population, very little research has been con-ducted with this small animal jn a turfgrass ecosystem However, there is sufficient evidence that suggests turf areas with little or no earthworm ac-tivity will accumulate thatch at a faster rate than areas with active populations. This is illustrated by research which has shown drastic reductions in earthworm populations or activity following the use of certain pesticides with a subsequent increase in thatch accumulation. It appears rela-tively certain that there is a rela-tionship between earthworm ac- tivity and thatch. How do earthworms aid in thatch decomposition or slow down its rate of accumulation? In addition to pesticides, what other factors affect earthworms? What can a turf manager do to insure an active earthworm population? These questions can best be answered by reviewing the biology of this soil inhabiting animal. Earthworms are invertebrate animals which form an impor-tant group of annelids, or seg- mented worms which live in the soil. They range in size from a fraction of an inch to the giant earthworms of Australia or Brazil which have been found to be more than 11 feet long and weighing up to one pound. There are about 1,800 species of earth- worms distributed throughout the world. The most common worms found in North America belong to the family Lumhricidae, which include the common nightcrawler or Lumhricus terrestris. It is impor-tant to realize that different species of worms behave differently. For instance, only a few species have permanent burrows and produce casts. Earthworms derive their nutri-tion from many forms of organic matter including dead or decom- posing plant material, living pro-tozoa, nematodes, bacteria, fungi or other microorganisms, and decomposing remains of large and small animals. One of the major factors which affect the distribution and population of earthworms in the soil, is the availability of organic matter as a food source. Generally, if there is little organic matter in the soil, the earthworm population will he small. Effect of earthworms on soil. Earthworms have long been known to improve both the chemical and physical properties of soils. For example, the frag-mented organic matter in soil is consumed by millions of bacteria and various enzymes. These ele-Thatch on left is from well fertilized turf with no earthworms. On right, thatch is diluted and decomposed by earthworm casts. ments or nutrients are then released from the worm to the soil for plant use. Some studies have shown that when earthworms were present, significant increases of available nitrogen, phosphorous, potassium, calcium, magnesium and molybdenum were found in the soil. The physical properties of soils are also improved by earthworm activity. The improvement in soil structure is through the activity of ingesting soil and the partial breakdown of organic matter in the gut. These two fractions are then mixed together and excreted. In addi-tion, the burrowing of the worm through the soil brings the deeper sub-soil to the surface as well as well as the movement of Ibro introduces trimmers to be called You work hard for a living.

It has been shown that soils with earthworms drain from four to 10 times faster than soils without earthworms Earthworms have long been known to be critical in the decomposition of plant organic matter. Most research has been conducted in conjunction with traditional agricultural farming systems. For example, in apple orchards earthworms have been shown to remove up to 90 percent of the fallen leaves from the soil surface during the fall and win-ter months. In orchards with lit-tle or no earthworm activity, a thick organic mat develops at the soil surface. Field experiments in permanent pastures have shown similar results. Very little work has been done on their ef-fects on turfgrass communities. A recent study shows that lawns with one-half inch or more of thatch average less than five earthworms per square yardf whereas lawns with little or no thatch average more than 33 worms per square yard. A correlation obviously exists be-tween thatch accumulation and earthwrom popu-lations. However, as already mentioned, it has been well documented that a correlation exists between thatch accumulation and earth-worm populations. For example, a recent study conducted on 30 home lawns in Columbus, Ohio, showed that lawns with one-half-inch or more of thatch averaged less than five earthworms per square yard, whereas lawns with little or no thatch averaged more than 33 worms per square yard. Earthworms act on organic matter deposited on the soil sur-face in a number of ways. They ingest bits of partially decom-posed roots, stems and leaves from the surface and that which is mixed with the soil. The in-gested material is then frag-mented in the earthworm's giz- zard. Approximately 18 to 36 hours after ingestion the earth- worm excretes the further decomposed organic matter in the form of casts on the soil sur-face and at various soil depths. Research has shown that earthworm casts may contain and Mowers good enough Professionals. 30cc Trimmer I Cutter 21cc Trimmer -< y.jt¿>Vi ' ' < ; raft . : a> AlU '/Jil V Got tougher jobs?

Worm casts also contain enzymes such as proteases, anylases, lyases, cellulases and chitinases which continue to break down orgainc matter. The effects of surface deposited casts can be of particu-lar importance in organic matter decomposition. It has been es-timated that 7.5 to 16.1 tons per acre of casts can be deposited an-nually. This is equivalent to a soil layer 3/16 inch deep spread over the entire area, or in other words, a naturally occurring an-nual topdressing. Therefore, earthworms can potentially aid in the decomposi-tion or control of thatch in three ways: Ł Direct ingestion of small pieces of organic matter. Ł Incorporation of micro-organisms and enzyme-rich casts into the thatch layer. Ł The removal of loose leaves and stems from the soil surface to deeper soil depths. Management practices. What can the turfgrass manager do to insure maximum earthworm populations and activity? Earth-worms and the environment in Earthworms can be a tremendous asset to the turfgrass manager. Their influence on the physical and chemical properties of soil have a definite affect on the health and vigor of turf. which they live are quite com-plex. However, there are several management practices or precautions which can affect earthworm populations. 1.) Discriminate use of pesticides: This is one of the most crucial aspects of avoiding total elimination of earthworms from a given turf site. Several pesticides have been shown to be toxic to earthworms. (See table 1 and 2 on pages 18 and 28.) Past or present use of these materials can be the major factor responsi- ble for none or limited numbers of earthworms being present in the turf environment. However, pesticides do not necessarily have to act directly on the worm for the actiity to be decreased. It has been suggested that pesti- cides sprayed on the surface of organic matter can change the palatability of that material to the point that it will be rejected by the earthworm. It should be emphasized that timing, rate, method and frequency of application will also determine the overall effect of a particular pesticide on earthworm activity. 2.) Soil and thatch pH: Most earthworms can be found in soils with pH's ranging from 5.2 to 9.0. However, most species prefer soil with a pH of about 7.0. To in-sure maximum earthworm ac-tivity, low pH soils and thatch should be limed sufficiently to bring pH into the neutral range. 3.) Soil moisture: Since earth-worms are composed of 75 to 90 percent water, it is important to to page IB THATCH from page 17 keep soil moisture at an ade-quate level. Although earth-worms can survive drought con- ditions, their activity decreases. Under prolonged drought, earth-worm populations will decrease dramatically and it may take up to two years of favorable con-ditions for the area to repopulate. As a rule, soil mois-ture content between 15 and 30 percent is most conducive for maximum earthworm activity. Conversely, earthworms will migrate from a water saturated soil. In general, they prefer a well aerated medium to fine tex-tured loam soil. In most cases, few if any will be found in soils high in sand content. 4.) Compacted soils: The beneficial burrowing of earth-worms and their surface activity can be significantly reduced by a hard, compacted soil. Human and vehicular traffic should be directed away from wet and poorly drained soils which are more prone to compaction. It may also be necessary to core the turf area to relieve the compac-ted condition and improve aera-tion. 5.) Seasonal activity: Earth-worm activity is at a maximum during the spring and autumn months and may be completely absent at other times of the year. This activity closely parallels soil and air temperatures. Earth- worms are most active when soil temperatures are between 60 and 70 degrees Farenheit. Usually they burrow down in the soil below the frost or heat line. Earthworm activity drops off dramatically during the hot, dry summer months. Activity can be encouraged through these stress periods by keeping the soil cool and moist. This can be accom-plished by providing adequate irrigation and in some cases a mulch. Earthworms can be a tremen-dous asset to the turfgrass manager. Their influence on the physical and chemical properties of soil, along with their ability to decompose organic matter can have a definite beneficial affect on the health and vigor of turfs. Drawbacks to earthworm activity. There are some poten-tial drawbacks to an active earth-worm population in a turf area. to page 28 Table 1.

During the last several years a variety of biological dethatching products have been marketed throughout the country. The products have consisted of a number of ingredients including enzymes, plant hormones, yeast organisms and soil microbes. In addition to increasing the decomposition rate of thatch, statements have been made about the beneficial aspects of these materials on turf such as improved color, increased shoot density, deeper and more extensive rooting, decreased disease activity and improved soil structure. Although many of these products differ in their composition and proposed mode of action, they all claim to be a fast, easy and relatively economical means of controlling thatch and improving turfgrass quality. Unfortunately, as desirable as these materials appear to be, extensive university testing across the country has yet to find any beneficial effects of these materials on thatch decomposition or turfgrass quality. When one considers the complexities of a turfgrass ecosystem, it is not surprising that these products have failed to perform as claimed. For example, research has shown that contrary to popular belief, the thatch medium is rich in soil microorganisms. In fact, thatch will often contain a greater number of microbes than the underlying soil. Even the use of most common turfgrass pesticides have only a minimal effect on thatch and soil microbes. Usually microorganism populations are reduced for only a short time, this is followed by a subsequent increase in number to the original level. Therefore, the theory of introducing microbes into a "sterile environment" as thatch is believed to be, is in most cases, incorrect. It is also unlikely that the introduction of microbes would increase the number of that decomposing microorganisms to the point that the rate of thatch decomposition would be improved. This is true because: (1) the number of alien organisms that could be introduced would be small in comparison to what is already present in the thatch and soil. (2) alien microorganisms would not survive any appreciable length of time following introduction due to competition with and antagonism by the other naturally occurring microbes in the thatch and soil. In addition, certain microorganisms cannot adapt to the environmental extremes found under field conditions. For example, the yeast organism Saccharomyes cerevisiae which is the active ingredient in some biological dethatching products, is not at all adapted to hostile environments such as those found in thatch and soil. In the case of this particular organism, even if it was able to survive under natural conditions, it's effectiveness in promoting thatch degradation would be limited since it is capable of utilizing only short chain or simple sugar molecules as a carbon source and not to page 29 AQUA-GRO M —O^ADIKIN AN Irregular growth of turf in stratified soil ^ when maintained W^ with plain water I Recovery of same j area in two weeks when maintained 1 with Aqua-Gro and 1 water Ł Compensates for poor soil mixtures and soil stratification Ł Helps eliminate hot spots Ł Allows for the rewetting of B&B stock and the establishment of sod.

If the cost of money is less than the rate the company can lift its prices, it can make sense to borrow to ex-pand sales regardless of interest rates. For example, a lawn care company that pays 15 percent in-terest on a sum equal to two month's sales is really increasing product costs by only 2.5 percent. If the company can boost prices even modestly, the cost of the money is minor when the loan is for a short period. Gross dollar profits will go up despite the high cost of money. If the loan is only for a few months, the cost is minimal, according to Small Business Report. To get more information about the magazine, contact: 497 Lighthouse Ave., Monterey, CA 93940.

SURVEY Landscapers average 4.2% annual profit The average U.S. landscape con-tractor does an annual volume of $784,700 with a profit of 4.24 per-cent, according to a study re-cently published by the Associ- ated Landscape Contractors of America (ALCA). The study, the 1979 ALCA Operating Cost Ratio Study, is based on a survey taken by the association of the landscape contracting industry throughout the U.S. during 1979. The survey encompasses financial statistics associated with both the association's In- come Statement and the Balance Sheet. The Balance Sheet data, for example, reveals that the typical firm has assets of slightly more than $518,000 including fixed assets of $171,000. The typical firm also has liabilities of $321,000 and capital of $197,000. The 40-page study is based on a survey taken among the landscape industry, the ALCA membership and others and was compiled from a total of 126 com-pleted survey forms. The in-dustry composites (average/me- dian data) is presented for the total industry, seven geographic regions, and for four size categories. The study is being distributed to all firms who participated in the survey. It is also available for purchase from the ALCA office, for $10 to ALCA member firms, and $25 to non-members.

The above statement is true, but if lawn care operators diagnose turf diseases according to the photos which appeared in the April issue of LAWN CARE IN-DUSTRY (page 28), they will un-doubtedly lose more customers than they retain. Unfortunately, the captions which appeared under the 11 photos of various turf diseases were in the wrong positions. LAWN CARE INDUSTRY apologizes for the error. Below are the photos which appeared in the April issue, along with the correct captions. The accom-panying chart spells out when the most troublesome diseases are likely to appear on home lawns. Leaf spot, B i p o I a r i s sorokiniana, appears most often during the cool, moist weather of spring and fall, but it can also develop throughout the summer. It is characterized by brown or tan spots on the turfgrass' leaves and stems. As the disease spreads, it produces large brown patches of of dead turf. Turfgrass infected by brown patch, Rhizoctonia solani, is at first purplish-green in color, but turns to light brown as the dis-ease develops. This disease is prevalent from July through Sep-tember. Dollar spot, Sclerotinia homocarpa, generally occurs in the spring and fall, but also can appear throughout the summer. It is characterized by brown or bleached patches and leaf spots with hourglass-shaped lesions. Stripe smut, Ust i I ago striformis, is easily recognized by the black, sooty spores which appear on the turf plant. It is most prevalent during cool periods from September through October and April through July. Red thread, Cortecium fuciforme, is identified by the red, threadlike structures which appear on the grass leaves. It is most likely to occur in the early spring or late fall. Pythium blight, Pythium aphanidermatum, generally begins as a dark, greasy area on water-soaked areas of turf. It is also characterized by fluffy whtie mycelium in the early morning. Pythium blight occurs in the summer from July through August. Predictably, snow molds occur between October and April, throughout the winter months. However, snow cover need not be present for some types of snow mold to develop on home lawns. Powdery mildew, Erysiphe graminis, occurs during cool tem-peratures in the spring and fall. It is characterized by a grayish color coating which appears on the upper leaf surface in a pow-dery form. This disease is com-mon shaded areas. Fusarium blight, Fusarium spp., is most often characterized by a circular area of reddish brown grass with green grass in the center. This is called the "frog eye" symptom. Fusarium blight appears on home lawns from July through August. Melting out, like leaf spot, also appears in the spring and fall of the year. > ? n > 70 m z a c CO TO 2 > Fusarium blight Stripe smut Cold temperature brown patch Grey leaf spot foliar symptoms Powdery mildew Spring dead spot Ilelminthosporium melting-out Š by Dan Moreland, assistant editor < S oc H c/D D Q Z w a: < u z £ < _3 Customer education: Do the benefits justify the cost? Lawn care businessmen depend on customers to properly care for the lawns in between service calls. Therefore, it's in the businessman's best interest to educate his clients in lawn care basics. It is generally agreed that in order to succeed in the lawn care industry proper employe train-ing is essential. Therefore, most lawn care companies conduct educational programs for their technicians, whether it be a one-week accelerated training course or eight hours of "hands-on" field work. Yet, many lawn care businessmen neglect to educate the single most important individual associated with their company, the client. In virtually no other industry is the owner of a business more de-pendent upon his client for the ultimate success or failure of his program than in the lawn care in-dustry. The customer who pur-chases a rug cleaning service does not criticize the cleaners for a poor job if his children dirty the carpet soon after the cleaner leaves the premises. Yet, the same customer will blame his yellow lawn on a lawn care operator even if he is the in- dividual directly responsible for the problem, (i.e. The customer scalped the turf with a dull mower blade or failed to water the lawn properly.)

"If you're forced to visit a customer every time he has a question, you're increasing costs," Ober said, "but if you can answer those questions without a visit from a service rep, you're saving money." Ł Fact sheets: Lawn care com-panies have also developed fact sheets to help the homeowner cope with more serious lawn care problems like disease and insect encroachment. Fact sheets are generally more extravagant than data sheets and, not surprisingly, more ex-pensive to produce. Typically, they consist of editorial material, along with four-color photo-graphs of the problem in ques-tion. They also contain a brief description of the problem, how it is identified, and how it is go- ing to be treated by the lawn care professional. Cost is five to seven cents per unit. Ł Newsletters: Some of the bet-ter established lawn care com-panies also provide newsletters to their customers on a regular basis. The newsletter format allows for a more in-depth study of various lawn care problems, but is generally too expensive to produce for small to medium-sized lawn care companies. Cost is 20 to 30 cents per unit. "By providing a newsletter you're trying to get the customers you already have to feel a closeness with your company," Ober said, "so they don't go shopping for somebody else. You can do this by stressing the special consulting services you provide and by showing your customers pictures of your lab-oratories and technical people." Ł Telephone spots: Some com-panies have even gone so far as to prepare weekly lawn care tips on a recording device which customers can listen to merely by dialing a special phone number. These lawn care "hotlines" serve as a quick reference tool for many clients. Further, because the phone service is a novelty item, many customers remember the tips longer and make it a practice to call the lawn care company every week. Prior to selecting any of the aforementioned educational tools to enlighten customers about proper lawn care, it is nec-essary to be aware of the metamorphisis of today's lawn care client. "When we started out in 1973 we were dealing with a different type of client," Faulring said. "They were generally older peo-ple, living in more mature neigh- borhoods who had a 'do-it-yourself' background. "Then there was a transition period in 1975-76 when we began serving a much younger client. They were more scrutinizing and wanted to know specifics about everything we did. "But now that volume lawn care is established," he added, "the customer is not so con- cerned about results and price. They like to have this back-ground information, but it might not be as valuable to them as it was five years ago." Ober, like Faulring, is well aware of the changes in con-sumer attitudes during the past decade. "I think people are definitely more knowledgeable about lawn care," he said. "You can see it in the way they shop for a service and their knowledge of different pro-grams. "But you could probably argue the other side of the coin too; that because people used to take care of their lawns themselves, they were more involved, and there-fore knew more about it. "I guess you could be torn both ways," he added, "but I think that as the customer becomes less interested in doing it him-self, it becomes that much more important for us to let them know just exactly what we are doing. So I think this (educational material) is important." Besides its obvious advantages as an educational tool, Faulring also views printed material as beneficial to promotion. "Those printed items are the biggest sales tool we can develop," he said. "We would like to inter-view each customer, but time and scheduling doesn't permit us to do that. "We may get 20 leads, but only be able to contact five people when we visit their homes. We can usually sell those five con-tacts, but what about the 15 we don't see? In those cases, the literature we leave at the home will do a big part of the selling for us." Ober also stressed the impor-tance of customer-technician contact when the field person-nel visit the home lawns. "Too often technicians visit a job site, spray the lawn and leave the site unnoticed." But educational material serves to keep the lines of com-munication open between a com- pany and a homeowner through-out the year. Further, it answers many of the customer's ques-tions, thereby reducing service calls and bothersome phone calls. "It's almost like the squeaky wheel situation," he said. "You only hear about it when it's not doing the job for you." In short, printed material serves as both a sales tool and an educational aid. Is it effective in both these roles? Perhaps, but it is difficult to be sure because no hard data is available on the sub-ject. However, Hydro Lawn's Faulring is convinced of the merits of educating the homeowner through printed means. "It's just like when you go out to buy a new car," he said. "You like to take the brochure home and thoroughly read it.

Many firms in the liquid lawn care industry have numerous materials handling problems associated with buying dry prod-ucts in bags for making solutions in the spray truck. Some of these problems can be solved by buy- ing liquid fertilizer solutions. Some dry handling problems are: Ł Storage problems include the facts that it must be kept dry, un- der a roof and unbroken. Ł Time and/or equipment is needed for unloading a delivery truck. Ł Loading the spray truck re-quires time, effort, accuracy and bag handling. This can cause morale problems. Solution fertilizers can solve problems: Ł Tank and fill station can be outside. Ł No labor or fork lift needed to unload. Ł The job of filling spray trucks becomes a matter of pushing but-tons and watching the meter. This system is easy to operate and also very accurate. > different companies receive fer-tilizer deliveries. Some com-panies keep their applicators in to unload by hand a truckload of bags; the loss time can easily amount to half a day for five ap-plicators if the delivery is late. With a liquid system, the transport driver could put the fertilizer in your tank and your secretary can sign the papers. This requires no labor or equip-ment. When equipped with a good meter, the liquid fill system is extremely accurate and easy to operate. All these factors can contrib-ute to a more efficient, more ac-curate and more productive lawn care business. LESCO BLEND See for yourself what CBS LESCO Blend can do.

Breeding programs at Rutgers and Pennsylvania State University have produced new medium textured perennial rye-grasses which have significantly expanded the capability of pro-fessional turfgrass managers. However, it is extremely impor-tant that the lawn care operator be aware of this turfgrass' capabilities and limitations. Some of the strengths of the perennial ryegrasses are they ex-hibit good traffic bearing charac-teristics, germinate and establish quickly, have the ability to with-stand low mowing heights, and they blend well with Kentucky smoother transition back to bermudagrass than has been possible with annual ryegrass. Some weaknesses, as observed in Virginia, include disease susceptibility, non-uniform up-right growth habit, lack of mow-ing quality, slow lateral growth habit and a lack of seedling winter-hardiness. The perennial ryegrasses ap-pear to be extremely susceptible to Pytbium spp. and Rhizoctonia so 1 an i activity during hot weather. Unpublished data by Virginia Tech's Dr. H.B. Couch indicates there is a range of varietal resistance to these organisms. As a group of grasses, the traditional perennial rye-grasses appear to exhibit less resistance to these hot weather diseases in the field than the improved varieties. The ryegrasses are also sus-ceptible to Helmintbosporium sativum and Corticium fuci-formo (Red thread. Disease sus-ceptibility is currently the major drawback in the use of the im-proved perennial ryegrasses. Another disadvantage is in early spring and late fall the rye-grasses exhibit rapid and relatively upright leaf elongation rates which necessitate more mowing in bluegrass-ryegrass mixtures, than in straight blue-grass stands. Mowing quality is also considered poor on the perennial ryegrasses. Citation and Diplomat have shown the best season-long mowing quality. However, the majority of the commercially available peren-nial ryegrasses do exhibit poor mowing quality at one time or another during the year. Perennial ryegrasses germinate quickly, 1)lend well with Ken-tucky bluegrass, with-stand low mowing heights and exhibit good traffic-bearing characteristics. bluegrass. Further, perennial ryegrasses grow four to five weeks longer in the fall and green-up four to five weeks earlier in the spring as compared to Kentucky bluegrasses. This can be either an advantage or a disadvantage. In situations where the exteded growing season is needed, it certainly is an advantage to have this extra growing period. However, in situations where this simply means eight to ten more mowings a year, it is an added cost. The improved perennial rye-grasses have also exhibited good short term drought color. During 20 to 40 day periods with limited water availability, they have maintained good green color in situations where Kentucky blue-grass has gone dormant. It is likely that they have less ability to withstand long term drought than Kentucky bluegrass. The vigor of the improved perennial ryegrasses has been an extreme advantage to the lawn maintenance industry in that it has made possible the successful overseeding of semi-thatchy areas. In the past, the limited seedling vigor of Kentucky blue-grass made it difficult, if not impossible, to successfully intro- duce new turf varieties into lawns where thatch depth ex- ceeded one quarter of an inch. Perennial ryegrasses have also been excellent for overseeding bermudagrass on home lawns. Their quick germination and desirable texture and color have provided excellent winter quality, and their ability to per-sist into the summer provides a In view of the fact that peren-nial ryegrasses are exhibiting ex-treme summer disease suscep-tibility in transition-zone climates, it is of major concern that they have shown a tendency to be extremely aggressive in certain situations when mixed with Kentucky bluegrass. The degree of aggressiveness is, of course, dependent on several factors including what variety of ryegrass is mixed with what variety of bluegrass. However, in studies seeded at Virginia Tech in April of 1972 containing 87.5 percent Merion Kentucky bluegrass and 12.5 per-cent Manhattan perennial rye-grass (bluegrass: ryegrass seed ration of 69 to 1), the ryegrass made up 58 percent of the ground cover by April of 1977. This does not appear to be a serious prob-lem where ryegrass is not ex-posed to hot weather disease. However, this could be a serious problem in areas where high Control 15 major lawn pests with versatile SEVIN carbaryl insecticide. They nip, munch, burrow and bite.

And residents can resume using the grounds or yard as soon as the spray dries. There's a choice of ä temperatures and excessive moisture and humidity are pres-ent. This aggressiveness would significantly increase the prob-ability of losing the ryegrass-dominated turf to summer dis-ease. Perennial ryegrasses also do not exhibit good long-term shade tolerance. However, their ex-tremely fast germination and es-tablishment rate does allow development of a turf in heavily shaded areas which will last 100 to 150 days. This certainly is an advantage over what we have been able to do with the existing slow-establishing Kentucky blue-grass. In summary, as one considers using the perennial ryegrasses in a turfgrass management pro-gram, it is important to be aware of their strengths and weak-nesses. Their disease suscep-tibility is a serious concern and is more serious in areas where hot weather disease activitv is ex-Table 1.

In areas where summer disease pressure is heavy, the perennial ryegrasses are going to be extremely limited in their abil ity to provide quality turf-grass over an entire growing season. At this point in time, the improved perennial ryegrasses are not, in my opinion, capable of providing the level of season-long quality we associate with a good Kentucky bluegrass mix-ture. The perennial ryegrasses should be used primarily as a support or specialty grass in areas where summer disease potential is high. In these areas, they should be utilized with the realization that they will require a fungicide program and may re-quire annual reseeding to thicken the turf. When one compares Kentucky bluegrasses as a group of grasses with perennial ryegrasses as a group of grasses (Table 1), it is obvious that the perennial rye-grasses have provided us with improvements in establishment rate, spring green-up, low mow-ing tolerance, short term drought color and better root-soil bond. They have also made a signifi-cant contribution to our ability to produce quality turf in the climatic transition zone. Hope-fully, the breeding programs un-derway at several universities and companies will provide us with stronger perennial rye-grasses to use in our attempts to produce quality turf. DISEASE Powdery mildew attacks plants, turf Powdery mildew, a fungal dis-ease that attacks turfgrass and a wide variety of ornamental plants from April through July, is easily identified by a white pow-der on plant leaves. "Affected leaves are often dis-torted and fail to develop prop-erly," explained Dr. Wendell Home, plant pathologist with the Texas Agricultural Extension Service, Texas A&M University System. "If not controlled the fungus may cause leaves to turn yellow and drop, thus weakening plants that fail to fruit or flower properly." Powdery mildew thrives in cool, dry conditions as opposed to warm, moist conditions for most leaf-spotting fungi. It also seems to develop most rapidly in areas of poor air movement. "Roses and crape myrtles are commonly affected plants," Home said. "Depending on weather conditions, they may es-cape damage one year and be af-fected seriously the next." The plant pathologist suggests that lawn maintenance profes-sionals check plants closely for powdery mildew and to take con- trol measures if necessary. Fungicides that prevent powdery mildew include Benlate, Ac- tidione PM, Karathane, Phaltan and sulfur. Use sulfur only dur- ing cooler parts of the growing season since it may cause leaf bronzing when temperatures are high. Two to three applications of fungicide may be required to control the fungus. Powdery mildew that attacks euonymous is the most difficult to control, Home added. Gar-dens with this problem may want to replace euonymous with plants resistant to the disease. Wax leaf ligustrum, for example, mjght be acceptable. "The key to controlling pow-dery mildew is to recognize it early and to apply a fungicide before serious damage is done," Home said. "This will help to in-sure an attractive landscape." > ? z o > 50 W z a c 03 H Ł< > four formulationsŠ sprayable, wettable powder, flowablesand SEVIMOl! 4, a liquid blend of SEVIN and molasses.

THATCH from page 18 For instance, burrowing of the large earthworms in the spring can disrupt a pre-emergent her-bicide barrier and bring buried weed seeds to the soil surface where they may germinate. Also, following a heavy rain or irriga-tion, earthworms may leave their burrows and move onto sidewalks and driveways where they are stepped on or run over by human and vehicular traffic. This is often times objectionable. Earthworms are not a panacea for all lawn problems including thatch development, but just one of the many important compo-nents of the turfgrass environ-ment. In summary, there is much to be learned about earthworm behavior under various turf com-munities and different manage-ment programs.

However, before a turf manager attempts this, it would be wise to ascertain the factors responsible for their absence or decreased activity. If a problem such as improper pH, poor drainage, or use of a certain pes-ticide is not resolved, the in-troduction of worms into the soil will serve little purpose. Furthermore, even if these problems are resolved but a pesticide with a long residual such as chlordane, bandane or calcium arsenate is present in the soil, it may be years before their residues decrease to a level where worms can be introduced. Finally, not all species of earthworms will produce the same effect on all soils and plants. The fact remains that no one species of earthworm is responsible for all the beneficial contributions mentioned above, but a combination of several different species typically found under natural field conditions. UP 15 PERCENT Fertilizer use ahead of last year's levels In most respects the pace during February for U.S. fertilizer pro-ducers was much like that of previous months during the current fertilizer year, according to a report released last month by The Fertilizer Institute. "Production continued to run ahead of last year's level for the July-February period with an eight percent increase, while domestic disappearance showed an increase of 15 percent," said Edwin M. Wheeler, president of the Institute. "Among the basic materials," he added, "an- hydrous ammonia production continued to increase its lead this year over the past fertilizer year." HHHHHHHHHHHI Fertilizer produc-tion continued to run ahead of last year's level for the July-Feb-ruary period, with an eight percent increase. ŁŁŁŁŁŁŁŁ¡¡ŁŁŁŁŁŁI Increases in domestic dis-apperance for the July-February period were applicable to each of the nitrogen, phosphate and potash groups, he said. Potash products led other nutrient groups in terms of percentage, with an increase of 23 percent over a year ago for the eight-month period. Nitrogen product disappearance increased 15 per-cent and that of phosphates, 10 percent. Referring to export/import trade during the July-February period, Wheeler said that im- ports increased 22 percent, led by muriate of potash and am-monia. Exports, however, decreased six percent during the period with largest decreased oc-curing with phosphates. February ending inventories for nearly all products were well below last year's levels, he said. COMPANIES 3m expands distribution of its plant growth regulator Embark brand plant growth regulator, developed by 3M and released for limited distribution in 1978, will be available in a larger number of regional areas this year, according to the manu-facturers. The growth regulator can be applied to a variety of popular turf species including Kentucky bluegrass, tall fescue, common bermudagrass and several native California grasses and broad-leaves. It reduces lawn mowing by temporarily inhibiting the growth of these plants for up to eight weeks. It also suppresses seedhead formation. Because Embark plant growth regulator results in less frequent mowing and trimming activities, it can cut mowing costs, allow reallocation of labor and materials and help reduce mow-ing accidents and equipment damage. Further, proper spring application can extend suppres-sion until normal turf growth slow-up in mid-summer. Applicaton of the growth regulator is made to healthy, ac-tively growing grass with stan-dard spraying equipment and calibrated nozzles that can apply 15 to 150 gallons of finished spray per acre. Distributors of the prod-uct are located primarily in the northern half of the United States. However, 3M will also sell directly to interested con-sumers in other parts of the country.

As with the introduction of microorganisms, the use of plant hormones to stimulate existing thatch and soil microbes is unlikely to result in increased thatch decomposition. Research has shown that plant hormones may be inhibitory to some microorganisms and stimulating to others. Likewise, the application of various thatch degrading enzymes is also unlikely to result in any significant thatch breakdown since the enzymes themselves would serve as a carbon source for many microorganisms found in the thatch and soil. Turfgrass species and/or cultivars, management practices, the underlying soil and climatic conditions all can have a profound affect on the nature of thatch. In terms of using any one of the currently available dethatching products, the lawn care professional would be wise to request unbiased, fully replicated and scientifically conducted research results to support the manufacturer's claims. tr > ?

EARNINGS LOWER BASF Wyandotte 1979 sales increase BASF Wyandotte Corp., Parsippany, N.J., an American member of the BASF group, has reported 1979 sales of $1.1 billion and net earnings after taxes of $9.7 million. Edwin L. Stenzel, president, said that compared to 1978, sales increased 28 percent, reflecting growth in the company's overall business, particularly in agricul-tural chemicals, including the turf herbicide Basagran. Net earnings were 12 percent lower than in 1978 due in part to start-up costs for new plants, one-time shut-down costs, and accelerated depreciation on ob-solete facilities. HERBICIDES bensulide, preparations of seven percent and 12.5 percent appear to give nearly as good crabgrass control as the bulkier, less con-centrated forms. Of herbicides available for use in water, ben-sulide is an effective spray treat-ment, being almost as effective in a spray as in its granular form, he said. "Proper timing of the treat-ment is essential for good results," Dr. Engel said. "Generally, most preemergemce herbicides are applied just prior to crabgrass germination because earlier application shortens the effective period of activity. It is difficult to time preemergence application by presence or lack of crabgrass seedlings, but timing the treat-ment with spring flowering of forsythia bloom may be a helpful guide. Since bensulide has com-parative long-term effectiveness, its date of application is often more flexible." Actor, state official receive Daisy awards Academy Award winning actor Cliff Robertson (second from right) and California Secretary of State March Fong Eu (far right) were honored for their contributions to the California environment and the state's landscape industry with Daisy Awards presented by the California Landscape Contractors Association (CLCA). With the two award winners are CLCA president Don Napolitano and his wife Nancy. Robertson, a native of California, was cited for his interest in preserving the California coastline and beaches. Eu was acclaimed for lending her prestige to the beautification of California. 31 > ? Z n > 70 m Z a c CD 70 2 > Second application sometimes needed for control of crabgrass Crabgrass germinates from April to mid-summer, making a residual action over the entire period a must. If other weeds, such as goosegrass, are present, then the herbicide needs to remain active even longer. Herbicides available on the market today differ in length of control. Herbicides for control of crabgrass include Tupersan, marketed by Du Pont Co., Wilmington, Del.; Balan, marketed by Elanco Products Co., Indianapolis; Dacthal, marketed by Diamond Shamrock Corp., Cleveland; and Betasan, marketed by Stauffer Chemical Co., Westport, Conn. Betasan is available also under other trade names. According to Dr. Ralph Engle, turfgrass specialist at Rutgers University, one of the top performers in controlling crab-grass over a period of years is bensulide (Betasan). "Sometimes a second preemerge application is made midway in the germination season in an attempt to better cover late germination of crab-grass or other weeds, but this does not control crabgrass that escaped the first application," Dr. Engel said. "The effec- tiveness of a second treatment depends on time of application and the amount of subsequent germination. However, ben-sulide has far less need of a second application than some other products due to its long residual action." Although bensulide remains active longer, if reseeding becomes necessary, it can be successfully inactivated by char-coal, Dr. Engel said. Because of a shorter residual, some herbi-cides, such as Tupersan, are of-ten used when reseeding is nec-essary, according to other ex- perts. Generally, low-analysis granular forms of preemergence herbicides are considered more effective than more concentrated preparations.

Write 206 on free information card Immaculate weed-free turf is the key to profit for the Lawn Care Operator Read how Trimec s> Turf Herbicide can help you improve the bottom line As a lawn care operator, you live in a glass house, and this has a direct bearing on your profits. Some busi-nesses can hide their mistakes, or shift the blame, or postpone the con-sequences, thus buying time to make corrections later when they're not so busy. But not you! If a few ugly weeds appear out of nowhere in one of your lawns, or if some trees and ornamentals show signs of damage, the finger points to you; you've got to do something right now or you may lose a customer as well as your chances for new custom-ers in the block. Fortunately, there's another side to the coin. If one of your lawns is as immaculate as a country club fairway, everyone in the block sees it and be-comes a prospect for you. The point is, you've got to do the job right the first time. You absolutely can't tolerate the emergence of stray weeds or damaged ornamentals. STRAY WEEDS: The weeds that plague lawn care operators are not dandelions or chickweed or other common sensitive weeds. To the con-trary, they invariably are a hard-to-kill variety usually thought to be rare Š until they showed up in your custom-er's lawn! Where did they come from? They're the natural consequence of using a narrow-spectrum herbicide in an area being fertilized and watered. The hardy weeds (those not con-trolled by the narrow-spectrum herbi-cide) are nourished by the fertilizer and water, and fight with the grass to fill the vacancy left by the demise of the sensitive weeds. Some of them win, and weeds that once were ob-scure become prominent. There's really only one efficient way to cope with the problem, and that is the Trimec way. Trimec is the one turf herbicide with a broad enough spectrum to get those hard-to-kill weeds along with Only Trimec gives you all these benefits Controls the widest range of broadleaf weeds Gets hard-to-kill species with one treat-ment. Wide safety margin for lawn grasses Minimum hazard from root absorption No vapor action after application Effective weed control In a wide temper-ature range Unique formula overcomes water hard-ness problems Treated areas may be reseeded within two weeks Non-flammable and non-corrosive In use Product stable several years above 32° F. Biodegradeable; friendly to the environ-Ł Bentgrass formula is also available the common, sensitive ones. How many broadleaf weed species will Trimec control? We're still looking for the troublesome broadleaf weed that Trimec will not control when applied at the right times and rate. If we do find such a weed, we'll be very much surprised. No other selective herbi-cide matches the broad spectrum of Trimec. ORNAMENTAL DAMAGE: Any broadleaf herbicide can damage trees and ornamentals if used indiscrimi-nately. But, for Trimec to cause such damage as a result of translocation, it would have to be applied at more than ten times the label recommendation. We estimate that more than 2 million lawns were sprayed with Trimec in 1979; there is not a single report of damage to trees or ornamentals. The reason why Trimec is so friendly to the environment, yet so powerful, is because no ingredient in Trimec is at a phytotoxic level. CUSTOMER RELATIONS: Be-cause most customer complaints and resulting service call- backs are caused by a genuine lack of informa-tion, we have designed an instructive Trimec door-hanger in response to the problem. It ex-plains Trimec's slow, thorough action and the time required to kill a weed, root and all, using the world's most efficient herbicide. Experience has shown this door-hanger to be highly effective in reduc-ing the number of complaints and call-backs because it tells customers what to expect Š in advance. A generous supply of Trimec door-hangers is available with your Trimec purchase. THE BOTTOM LINE: You can buy a narrow-spectrum herbicide that costs less per gallon than Trimec. But, on the bottom line, Trimec costs less than its less-effective contem- poraries. That's because it requires less chemical per acre for maximum weed control; and because it saves la-bor by doing the job right the first time.

First the bad news, and boy, is it a wowser. Last month we ran a feature on turf dis-ease identification and control by Dr. Joe Vargas of Michigan State University ("Dis- ease Management Will Be the Next Growth Area in the Lawn Care Industry", page 28). Along with the excellent copy, Dr. Vargas put together a quick-reference turf disease guide for our readers, and provided top-notch photos for identification of some troublesome lawn diseases. But somewhere between when we last saw the page that carried the identification photos and when it went to the printer, the gremlins that plague all trade magazine editors somehow switched around just about all of the identifying captions. We have re-run the photos with the correct cap-tions on page 21 of this issue, and thank all of you who noticed the colossal goof for calling us. Now the good news. In the April 7 issue of Advertising Age, the bible of the adver-tising industry, the lawn care industry received some substantial recognition right on page three. In a story titled "Green Grass Field Growing," associate editor Jen-nifer Alter zeroed in on the increasingly in-tense competition among major companies in the chemical lawn care industry. She quoted Toro president Jack Cantu (whose company last year acquired Barefoot Grass Lawn Service), Lawn Doctor president Tony Giordano, and Lawn-A-Mat's Stan Weber, in addition to myself. She used examples of Barefoot's literature and also that of ChemLawn Corp. to illustrate the piece. Some facts from the story: ChemLawn mails out 10 million per-sonalized self-mailers a year; Barefoot ex-pects a 50 percent sales increase this year, with marketing concentrated in the Midwest (they expect sales of $30 million to $50 million by 1985); and Giordano is look-ing for sales of $23 million this year from his 270 dealers. Alter pegged the industry at $200 million, quoting me, but I feel the market is closer to $900 million. However, it was an excellent article. If you didn't see it, drop me a line, and I'll send you a copy.
