School’s back in session, fall is around the comer and to me it somehow feels that the annual cycle has begun again. Other people may feel like New Year’s Day or the first day of spring is the beginning of the new year, but I have al­ ways felt it was the beginning of fall (maybe it’s all those years I spent in school...). From my earliest memories, September was always the time when my sister and I got new clothes, set new goals, made new friends. It was a time for new beginnings, for taking stock of where you were and making plans to get where you wanted to be. To me each year culminates in the arrival of summer, the high point of any year: backyard barbeques, vacations, long days and warm nights. All rested and refreshed, we look to fall as the time to get back to the books and back to work. For me the summer ends with the fall harvest: a time of plenty, of reaping what you have sown, of preserving the harvest and preparing to begin the cycle anew. Recently, my local newspaper had a front page article in the Lifestyle section about home canning making a comeback. People cite all kinds of reasons for the resurgence: qual­ ity, cost, family time. They are all lessons I learned long ago. Raised a Jersey girl, I didn’t grow up canning and preserving food, but after marriage to a Pennsylvania farm boy that all changed. But more important than the taste of summer fresh com served alongside our Easter ham, it is in the fall harvest where I think some of life’s most profound messages reside. Sometimes the extra effort really is worth it. All of us lead complicated, overscheduled lives, but there are times when that little extra effort pays dividends many times over. Is it a lot of work to hull strawberries, prepare and package them for storage? Absolutely. But as anyone who’s ever put fresh strawberries in their freezer in June and pulled them out in January knows... Is it worth it? Absolutely. Planning ahead makes all the difference. In a world where our days are sometimes scheduled down to the minute, planning ahead is the only way to make it through. Pick­ ing apples, turning them into sauce and canning them for the coming year takes time. You need to plan for it. continued on pg 4 Table of Contents Clippings President's Message From the Executive Director 2008 NJTA Patrons Green Expo is Coming!

Everyone has something in their life that they never seem to have time for. Identify those things and plan ahead to make them happen. You’ll be glad you did. It’s not about the destination so much as it’s about the journey. I read that somewhere, but it’s true. Life is about the journey, not the destination. So enjoy the journey. Turning pounds of tomatoes into spaghetti sauce can be fun when you do it with family or friends. After you finish making the sauce, throw together a simple spaghetti dinner and enjoy your handiwork. Just because it’s work, doesn’t mean it can’t be fun. 2008 Patrons Clippings & Green World would like to THANK our Patrons for their continued support.

Buckley, Director Soil Testing and Plant Diagnos­ tic Services, Rutgers University Albrecht M. Koppenhofer, Turfgrass Entomologist, Rutgers University William T. Crow, Associate Professor of Nematology, University of Florida Applied Turfgrass Research from Rutgers, the State University, and the New Jersey Turfgrass Association Introduction: Nematodes, also called roundworms or eelworms, are the second largest group of animals next to the insects. There are estimates of upwards to 500,000 potential species. Fortunately most nematodes exist free of any parasitic relationship (“free-living”). Free-liv­ ing nematodes occupy all ecological niches and feed on decaying animal and plant matter, algae, and bacteria. Some of the free-living nematodes are predatory, attack­ ing small soil-borne animals including other nematodes. Unfortunately there are nematodes that parasitize animals and plants. In dogs, heartworm is a common nematode parasite. On the other hand, several species have even been implicated as disease agents of insect pests. These nematodes have been formulated as biorational pesticides and are used in insect control programs with some success. Finally, we have the plant parasites. Roughly 3,500 spe­ cies of nematodes are known to be obligate parasites of plants. Most of these nematodes live in the soil and feed on plant roots, but some can be found in the foliage of herbaceous ornamentals or in the stems of conifers. A total of 13 types of plant parasitic nematodes occur in New Jersey soils. Direct injury from high populations of these nematodes is rarely a problem in grass cut above 1/2”. Table 1.

Male and female adults of a typical plant-para­ sitic nematode. Morphology: Plant parasitic nematodes range in length from 1/64 to 1/8 inch (40-320 pm), but are very thin and cannot be seen without magnification. Their bodies are translucent, so the internal organs show through the cuticle. They are unsegmented, but might have some segment-like or other ornamentation on the body. In some nematode genera there is sexual dimorphism - the male and female have different body shapes. A plant parasitic nematode is essentially a feeding machine that is much like a straw with a pump. At the front end there is a heavily sclerotized piercing-sucking mouthpart called a ‘stylet’. The stylet is strongly muscled and moves in and out of the body to feed. The stylet connects to a pump-like esophageal chamber called the median bulb, which aids the nematode in the withdrawal of plant fluids and serves as the transition to the intestine and excretory chambers. continued on page 7 An Integrated Approach to Nematode Management in Turfgrass by Richard J. Buckley, Director Soil Testing and Plant Diag­ nostic Services, Rutgers University Albrecht M. Koppenhofer, Turfgrass Entomologist, Rutgers University William T. Crow, Associate Professor of Nematology, University of Florida Green World njta Life History: Most nematode life cycles have males and females and/or self-fertilizing hermaphrodites, but in some species only females may occur (parthenogenic). The fe­ males or hermaphrodites lay eggs (as many as 1000 eggs over a 2- week time span in some species). Each nematode has five growth stages and molts four times, the first of which occurs in the egg, in a gradual transition to the re­ productive adult. This process takes roughly 4 to 8 weeks. In many species warmer soil temperatures speed the life cycle. Conditions that favor nematodes: Nematodes prefer warm soils but will be active anytime the soil temperature is above 40°F. They are semiaquatic and need soil mois­ ture to avoid desiccation and to allow movement. Soils at field capacity are ideal. Nematodes prefer sandy soils with larger pore spaces. We typically assume that USGA recommended sand-based root zone mixes for golf greens are perfect environments for nematode survival. Recent research from Rhode Island reports; however, that greens construction does not appear to influence nematode popu­ lations. Their studies suggest that the older the green, the higher the nematode population. The drawback to this re­ search is that most sand-based construction is much newer than the older soil-based greens in the study that had higher nematode populations. Population dynamics: Plant parasitic nematodes depend on a living host in order to complete their life cycle. They overwinter in all life stages and begin to increase in pop­ ulation as the soil temperatures warm in the spring. By most accounts, nematode populations peak in late-spring to- early-summer, grow slower or crash into the summer, and resume expanding to a second peak in late-summer. Nematodes are not uniformly distributed in the soil. They are found in diffuse densities of various populations or in “hot spots” that are randomly spaced throughout the turf area. Therefore, different core samples taken from dif­ ferent locations in the same turf area will have different populations. In research conducted at the University of Massachusetts numerous 1x4 inch soil cores were taken from a single golf course putting green. Each core yielded populations of stunt nematodes that varied from 50 to- 350 per core. A composite sample of all of the cores yielded an average of 196 stunt nematodes for that green. They also found that the concentration of nematodes varied through­ out the soil profile. At the 2 inch depth there were twice as many stunt nematodes than there were at the 4 inch depth. The diffuse nature of nematode populations and random distributions in the soil profile make proper sampling im­ perative in estimating nematode populations. Single cup cutter sized plugs that are submitted for population esti­ mates often provide misleading results. Feeding behavior: There are two types of feeding behav­ ior in nematodes. Several genera feed on the outside of the roots (ectoparasites). Some ectoparasites migrate up and down the root and feed in many locations and others re­ main sedentary and continuously feed in roughly the same spot. Several other genera feed inside the roots (endopara­ sites). Again, there are migratory species that move up and down the roots between the cells and sedentary species that remain and feed in a single location. Obviously, the endoparasites that migrate cause a great deal of damage to the root system. Pathology of infected roots: Nematode feeding causes different types of injury to the roots. Most notable is the overall reduction in biomass. Nematodes destroy cells di­ rectly by enzymes injected through the stylet. When there are enough feeding sites and enough cells are destroyed, lesions may be present on the root. In some cases, the number of root hairs is reduced and apical growth is af­ fected, so the roots appear stubby or stunted. Some of the endoparasites cause knot-like galls that distort the roots. The feeding sites can also act as infection courts either by mass cell destruction or when the endoparasites force their way into the plant, thus creating an opening for other pathogens to enter. Symptoms: Plants respond to any root-dysfunction with symptoms related to deficiencies of nutrient or water. Yel­ lowing and thinning of the turf, reduced vigor, and pre­ mature wilt have all been attributed to nematode feeding. Turfgrass that is slow to recover from stress, or does not respond to fertilization, might indicate root damage from nematodes. Since the distribution of nematodes is uneven in the soil and high populations are clustered into “hot spots,” the symptoms on the turf population will be seen as non-uni- form, poorly performing turf areas that correspond to the nematode “hot spots” in the soil. Nematode damage rarely is uniform or ends abruptly. Affected plants lack vigor, and so, have a reduced ability to handle periods of environmental stress, or in the case of sports turf, the rigors of turf management. It is not un­ common for these plants to die outright under the stressful conditions, or to be attacked by weak pathogens, like Col- letotrichum cereale, the cause of anthracnose, or Curvu- laria spp., the cause of fading out. Diagnosing nematode damage: Do not depend on aboveground symptoms or root conditions alone to diag­ nose nematode problems. Analysis of soil samples by a competent laboratory is the best method for determining continued on pg 20 Rutgers Turfgrass Research Field Days Recap The 2008 Rutgers Field Days were once again traffic and disease progression, as well as cultural a great success.

Todd Raisch arranged to have the Hospitality Area lo­ cated within the Turf Care Facility, which was in the middle of the Championship Course at the Ridgewood Country Club. It was a place where Golf Course Su­ perintendents and dignitaries felt welcomed and where much appreciated Grounds Department Volunteers and Staff were treated special and thanked for the pride they took in their efforts to present the finest golf course con­ ditions for the 2008 Barclays Golf Tournament. We all take great pride in the history of the fine gentle­ men who have served Ridgewood Country Club as Golf Course Superintendents. Their professionalism, along with dedication of their hard working staffs, made us proud of the golf course management profession. The Hospitality Area gave everyone the opportunity to participate in the golf course management atmosphere and network with peers at a PGA Tour stop that was the first leg of the FedEx Cup. The support we received afforded us the opportunity to donate the profits from our endeavors to the Golf Course Superintendents Association of New Jersey Foundation, The Golf Course Superintendents Association of Ameri­ ca Environmental Institute for Golf, and the New Jersey Turfgrass Foundation, (see pictures on next page) We would like to extend our thanks to the Ridgewood Country Club, The Barclays/PGA Tour, and Hospi­ tality Area Sponsors and Patrons for their generous support which made this endeavor possible.

NJTA’S HALL OF FAME AWARD by Keith Kubik The New Jersey Turfgrass Association’s Hall of Fame Award is “presented annually to a person in recog­ nition of a continuing lifetime commitment of dedication, service, and achievements contributing to the advancement of the turfgrass industry of New Jersey.” This award was first given in 1974. As the NJTA nears our 40th anniversary in 2010, we felt it was appropriate to highlight the past winners of our highest award. The following is a reprint from the “New Jersey Turfgrass Association 10th Anniversary Commemorative Book (1980). Jack Ormond (1976) Life began for Jack Ormond in a Nova Scotia farm house in 1907. In 1920, he became a Royal Canadian Mounted Policeman. In 1926, Jack gave up the life of a “Mounty” to accept a job in the U.S. working for a land clearing company that was preparing the way for the “South” course at Canoe Brook Country Club. When construction was completed, Jack remained on to accept the position of assistant superintendent which led to Superintendent in 1941 in which capacity he served until retirement in 1967. Always an in­ novator, he was the first to renovate his fairways and pioneer in the development of a crabgrass control program for large acreages. His highly manicured thirty six-hole golf course was always maintained to the finest degree of excellence. A modest man who vigorously shunned the limelight, his great example continues to serve as a beacon to all of those who knew him. He was a Superintendent’s Superintendent.

Buckley, Director Soil Testing and Plant Diagnos­ tic Services, Rutgers University Albrecht M. Koppenhofer, Turfgrass Entomologist, Rutgers University William T. Crow, Associate Professor of Nematology, University of Florida Applied Turfgrass Research from Rutgers, the State University, and the New Jersey Turfgrass Association the types of nematodes present and the potential risks those nematodes pose for the turf. The availability of nematicides is limited. They are expensive and hazardous. Sampling is inexpensive when compared to the cost of unnecessary or poorly chosen nematicide applications. Soil sampling for nematode analysis is much like sampling for nutrient levels. A 1” (2.5 cm) diameter soil corer is used to systematically sample the affected area. Take at least 25 cores to 4” (10 cm) depth and mix in a bucket. Remove a 1-pint (0.5 Liter) subsample, place it in a plastic bag, and keep it out of direct sunlight and in a cool place until it is shipped to a nematode detection service. If turf damage ex­ ists, take the samples from throughout the affected area. If possible, sample a nearby healthy area for comparison. If there is no damage, sample the area in a systematic way. If the intention is to set baselines and monitor the popula­ tion over time, choose an area no larger than 500 square feet and return to the same area at a later date for additional samples. To get a clear picture of the nematode dynamics on your site, it may be prudent to sample repeatedly during the season and to repeat the process over several years. Rutgers nematode resources: FS757 ‘Proper Sampling of Soil and Plant Tissue for Detection of Plant Parasitic Nem­ atodes’ is available from Rutgers Cooperative Extension to assist in the selection of a proper sample. Nematode assay submission forms are available for Rutgers Nematode De­ tection Service by phone 732-932-9140, fax 732-932-1270, or on the web at www.njaes.rutgers.edu/services. Damage thresholds: Injury thresholds signify the poten­ tial of a nematode population to cause damage. A number of thresholds have been established for most of the com­ mon nematodes in turfgrass. Some of the reported thresh­ olds are research based, but others are simply related to a researcher’s or practitioner’s personal experience. In many cases there is a great divergence in the numbers from source to source. In general, lower population thresholds can be found in reports from the south whereas higher population limits are tolerated in the northeast. Accepted thresholds for bentgrass and tall fescue are listed in table 2. It is important to note that for most nematode species on many of the major warm- and cool-season turfgrasses there are no known thresholds, therefore, one should use caution when trying to extrapolate from one nematode-turfgrass combination to another. Furthermore, nematodes rarely occur as populations of single species. Most of the time several different species are found associated with the same turf stand. This makes damage thresholds difficult to use in a practical way. Because thresholds only provide a guideline it is important to consider all factors when mak­ ing a control decision. Nematode management: Most turfgrasses can withstand some feeding by most kinds of nematodes if given sensible care. Direct injury from high populations of nematodes in New Jersey soils on grass cut above 1/2 inch is rarely a problem. It is not uncommon to have the highest popula­ tions of nematodes on turf in the spring and fall, when the turf is actively growing. Populations of nematodes often increase in root biomass for food. Management practices that reduce plant stress and promote vigorous root growth will help the grass tolerate the feed­ ing of very high populations of nematodes. Mowing the grass at the proper cutting height for the species, regular aerification to prevent thatch and compaction, proper fer­ tilizer inputs - based on soil test results - and judicious use of irrigation may provide relief by producing a healthier plant overall. It is also important to monitor and control other diseases. Remember, it is often the cumulative effects of several stress factors, living and non-living, that cause the decline of the turf. Biorational control: The biorational products, Ditera® (dried fermentation solids and solubles of the fungus My- rothecium verrucaria), Neo-Trol® (ground sesame plants), and Safe-T-Green® (linear secondary alcohols reacted with ethylene oxide) are labeled for nematode control in turf. There are many other plant-derived products on the market that make various claims regarding nematode sup­ pression. Some of these products are derived from herbs like pepper, clove, thyme, and wintergreen, or from vari­ ous trees and shrubs. For most of these products there is no efficacy data provided from legitimate research. In some cases, the products show nematode suppression in the laboratory, but few have maintained that performance in the field. In fact, field trials from Florida, South Carolina and Massachusetts suggest that these biorational products do not consistently suppress populations of plant parasitic nematodes and perform poorly when compared to tradi­ tional nematicides and fumigant products. continued on page 21 An Integrated Approach to Nematode Management in Turfgrass by Richard J. Buckley, Director Soil Testing and Plant Diag­ nostic Services, Rutgers University Albrecht M. Koppenhofer, Turfgrass Entomologist, Rutgers University William T. Crow, Associate Professor of Nematology, University of Florida Green World njta Applied Turfgrass Research from Rutgers, the State University, and the New Jersey Turfgrass Association continued from page 20 Biostimulants and soil amendments: You might hear of certain microbial biostimulants, compost products, or other soil amendments that are supposed to affect nema­ todes in various ways. Most of these claims are unfound­ ed. Researchers at the University of Maryland found that the addition of activated sewage sludge and poultry waste actually increased lance nematode populations on a creep­ ing bentgrass putting green compared with other organic nitrogen sources, which is contrary to reports that organic soil amendments are capable of suppressing plant parasitic nematodes. As with many of the alternate therapies mar­ keted for nematode control, efficacy data from University- based sources is lacking. Natural enemies: Many microbes, including bacteria, fungi, and actinomycetes, are parasites of nematodes. The bacterium, Pasturia penetrans, produces spores that stick to the nematode. Once the spores germinate and penetrate the nematode body, they proliferate and produce more spores that are released when the nematode ultimately dies from the infection. Another microbe, the fungus Arthro- botrys oligospora, produces hyphal rings that trap and con­ strict the nematodes as they pass through and touch them. Although there is promise with Pasturia, there are no com­ mercially available forms of these biologicals at the pres­ ent time. Entomopathogenic nematodes: The beneficial nematode Steinemema riobrave (BioVector®) shows some promise as a nematode control at high application rates, but is cur­ rently not labeled for use in that manner. Research con­ ducted by Ohio State and Virginia Tech Universities found that the application of these beneficial nematodes reduced the numbers of plant parasitic nematodes on golf course putting greens. At the University of Florida; however, in ten field trials no benefit was recorded using entomopatho­ genic nematodes to suppress plant-parasitic nematodes. Chemical control: The decision to use nematicides must be carefully evaluated. The simple presence of plant para­ sitic nematodes does not warrant chemical applications. Furthermore, when high populations of nematodes occur in the absence of damage to the turf, it is difficult to justify the application. If nematode populations exceed reported damage thresholds, there is appreciable risk to the turf, and all other management issues and stress factors are consid­ ered, nematicide applications may be useful in reducing nematode populations and improving turf quality. NemacurR: In New Jersey, fenamiphos (Nemacur® 3EC and 10G) was labeled for use on golf courses and in com­ mercial sod and seed production. In fact, Nemacur® has been the most widely-used and consistently effective ne­ maticide used on turfgrasses in the United States for the past 30 years. One of the properties of Nemacur® that makes it particularly useful is that it is the only turfgrass nematicide with systemic activity. This means that the ma­ terial is taken up by the roots of the turf where it can affect endoparasitic nematodes in the roots, as well as affecting ectoparasites in the soil. Fenamiphos is in the class of pes­ ticides termed “organophosphates.” These pesticides act on the nervous system of the target pest. Unfortunately, exposure also can affect the nervous system of non-target animals such as fish, birds, and people. Because of the health and environmental risks from organophosphates many of them have been taken off the market in recent years. Nemacur® may no longer be purchased legally af­ ter 2008. The loss of Nemacur® has stimulated great in­ terest in the development of new nematode management options for turf. Fumigation: Dazomet (Basamid®) is a granular product that is gaining popularity for turf managers as a tool for turfgrass renovations. The product, when used at the right temperature and soil moisture levels, releases methyl iso- thiocynate, which is the same active ingredient in older general use fumigant products like Vapam®. This mate­ rial can control many kinds of soil-borne pests including nematodes, fungal disease agents, insects, and weeds. It is labeled for a number of turf and landscape uses. In turf ar­ eas with chronic nematode problems, the renovation of the existing stand, using a product containing dazomet might be prudent. Remember that fumigants have no lasting ef­ fect, so nematode populations will begin to recover once the material dissipates. Furthermore, with no competition from other soil microbes that were killed by the fumigant, nematode populations may recover quickly. Curfew® soil fumigant: This is a fumigant nematicide that is labeled for use in the coastal states of the south­ east, but not in New Jersey. Curfew® (1,3-dichloropro- pene) is slit-injected into established turf as a liquid that then moves through the soil as a gas. It is a very effective contact nematicide and kills nematodes in soil, but does not have systemic activity. Curfew® is custom applied by a few approved applicators and labeling is sought on a state-by state basis. Therefore, the estimated number of sales in a given state must be high enough to justify a reg­ istration being pursued. It is unlikely that the economics would justify Curfew® being registered beyond the eight states where it is currently labeled. continued on page 22 GREEN EXPO is COMING! continued from pg 5 - Business topics, too...

Accepted Damage Thresholds for Plant Parasitic Nema­ todes on Selected Cool- and Warm-Season Turf ...NEMATODE MANAGEMENT continued from pg 21 Problems with nematicide use: No nematicide is equally effective against all nematode species. The endoparasitic species are particularly hard to control. Furthermore, the application of a nematicide product does not guarantee 100% control. There are always survivors, so nematode populations will recover over time. Finally, there are reports of enhanced microbial degrada­ tion of fenamiphos on golf greens after repeated use of the product. Repeated use of any pesticide to the soil over a long period of time will encourage the buildup of bacteria and other microbes that can metabolize (eat) the particular chemical. The net effect is a reduction in the effectiveness of the material. In Florida, there are reports of Nemacur® degradation at a rate 20 times faster than normal. Enhanced microbial degradation has been reported for over 200 soil- applied pesticides, so it would not only be prudent to rotate all materials, but to keep their use to a minimum. New chemistries: There is currently a lot of effort going into the discovery and development of new nematicides. New pesticide classes are being developed that look to be effective and yet safer than organophospates to non-target organisms. Molecular biologists and nematologists now know what every gene in certain nematodes does. This has allowed for development of pesticides that target those genes that are only present in parasitic nematodes. Cur­ rently field trials with some of these new chemistries are underway with exciting results. One of the good things about turf from a pesticide development standpoint is that it is a non-food crop. That makes it easier to get labeling since residues in food are not a concern. Also, turf is a high-value crop so there is a commercial market. There­ fore, many companies are looking to get their initial label­ ing for new nematicides for golf course turf. Within a few years some effective new turfgrass nematicides should be on the market for your use. The only drawback is that none of these new chemistries currently being evaluated are sys­ temic. This means that they will probably be more consis­ tently effective against ectoparasites than endoparasites.
