Your President, Ted Woehrle, CGCS VERDICT ON DDT When DDT first appeared in the U:S. in 1942, it seemed almost like a miracle drug. Cheap and efficient, it destroyed pests, reduced such insect- borne diseases as malaria, and brought bumper harvests. But over the years scientists found disturbing evidence, first publicized in Rachel Carson’ s Silent Spring, that DDT was harmful to animals too, and might threaten man as well. After 17 months of weighing the evidence pro and con, Environmental Protection Administrator William D. Ruckelshaus announced his verdict last week: “ DDT is an uncontrollable, durable chemical that persists in the aquatic and terrestrial environments.” Because it lasts so long, it can build up in fish and animals until it “ may have a serious effect” on human beings. With that, he imposed an almost total ban on the pesticide (exceptions: in cases of sudden epidemic, when DDT is the most effective means of combatting disease-carrying insects; shipment to countries where malaria is a problem; and usé on onions, green peppers and sweet potatoes in certain areas that are particularly vulnerable to pests). The ban will not go into effect until the end of the year, allow­ ing in using DDT’ s chief substitute, methyl para- thion, which is highly toxic but breaks down soon after being used. time to train farmers The ban was immediately chal­ lenged in suits filed by the manufac­ turer and processors of DDT. Another challenge came from the Environmental Defense Fund, which has been chiefly responsible for forcing the issue. It filed a court petition asking that the ban go into effect immediately and that it forbid all domestic applications of the one-time miracle.

Our host was Ron Abbott a new member of the Association. It was a first for most of us. Most of us are used to the Urban surroundings of our golf courses and the pleasant quiet surroundings were soothing to the nerves. The hills on the course were larger and steeper than most of us are used to. Ron had the course in excellent condition. I guess I’ m still a country boy at heart because I enjoyed the day completely. Our dinner consisted of Char- Broiled steak made outdoors with all the trimmings. to us The speaker of the evening was presented through Terminal Sales. Charlie Wilson of the Milwaukee Sewerage Commission spoke to us about the past winter and all of its related problems. His slide presenta­ tion is one of the finest in the world. Subjects covered were on: Poor drainage, plant breeding, grass muta­ tions caused by Gamma Radiation in the Laboratory. Some of the results from these programs, have produced smog proof Bermudagrass and salt tolerant highway grasses. Charlie mentioned that one of the is Sulfur. elements ignored most Sulfur deficiency often like Potash deficiency. Soil tests should be taken if in doubt. looks Grass clippings make excellent fertilizer - Don’ t waste them. Start a compost pile. The use of a tensiometer in measuring soil moisture is a great tool in turf management and we should consider buying one. A new weed and algae control on ponds has been quite successful in Florida and is now available. The product is called “ Aqua Shade” sold through Terminal Sales. It works as a coolerant in the water and kills plant life through obstructing sun light. It doesn’t harm irrigation ponds. Sounds great. One gallon treats one acre five feet deep. Another tip involved weed control in traps. Line traps with asphalt. Of course, you have to provide drainage. One of the last pictures showed a green that was basically dull brown except for a wide green stripe resulted when a newly sharpened mower was used. The remaining dull brown green resulted from a dull mower. A point worth remembering. Keep those mowers sharp! A caddy is a guy who stands behind a golfer and who didn’t see where it went either.

The first projects include any new construction or rebuilding done at least a year in advance. This would include tree removal and planting. Installation of utilities is next on list. This includes some 30,000 the feet of telephone lines and 10,000 feet of electrical cables all of which must be placed underground. Scoreboards, leader boards, tents, fence, TV camera towers and snow miles of roping and thousands of stakes used to hold the gallery roping are installed early. Decisions of toilet locations, trash pick up and mowing schedules come last. Regular turf maintenance continues through all of this.

R IE K E , Department of Crop & Soil Science, MSU Healthy, vigorous turfgrass leaves are about 80% water unless the plant is under moisture stress. At 60% it is badly wilted. The succulence of turf is due to the water content. This water is provided to the leaves by the root system, and most of the water is taken up by the tiny root hairs near the active growing tip of the roots. Sufficient water must be provided by the root system to satisfy transpira­ tion needs. When transpiration exceeds the rate that roots can supply water, the turf wilts. The amount of water used by the turf is a function of cli­ mate, water holding capacity of the soil, moisture level in the soil, and the management applied to the turf (1,2,3). In Michigan, Indiana, and Illinois the greatest difference between po­ tential water needs (évapotranspira­ tion) and precipitation occurs in July. Using average figures, about 4” of water will be the minimum needed during July in southern Michigan and northern Indiana. Unfortunately “ aver­ age weather” seldom occurs while the unusually wet or dry conditions are more typical. The summer of 1971 was unusually dry in central Michigan. For example, resulting in at least 6” of irrigated water as a minimum require­ ment in July. The water holding capacity of the soil is dependent on soil texture and rooting depth. Sands, of course, hold much less available water than soils higher in silt and clay. Rooting depth is also significant in that the plant can only obtain water from the soil to the effective rooting depth. Shallow in mi d- s umme r rooting of greens necessitates frequent irrigation since the available water is rapidly removed from the surface 2 to 3” of soil. careful and As water is removed, the remaining is held with greater tension water making it more difficult for the plant obtain sufficient water rapidly to enough. Wilting usually begins in mid-afternoon when the water use rate is is be-^ coming drier. the highest and the soil Water use rates are also affected by several management practices, such as mowing, wetting agents, cultivation, compaction, and by disease or insect attacks. Shallow rooting limits soil contact by the roots reducing the amount of water which can be taken up. For example, assume a bentgrass or Poa annua green has an effective rooting depth of 3” in July, and the soil is a fine sand which would hold 1.2” of available water per foot of soil. This would mean the turf can extract about 0.3” of water from the soil to that rooting depth. If the water use rate on a hot windy day is 0.25” per day, this shows the necessity of irrigating daily. On the other hand, if the water use rate is 0.1” per day, irrigation fre­ quency could be reduced. Factors which tend to cause short root systems on turf are heavy nitrogen fertilization, heavy irrigation, poor drainage, compaction, short mowing height, acid soil conditions, root injury due to pests or chemicals, or environmental conditions, which may tend to reduce root growth, such as high temperatures (1,2). or poor drainage, results Too much water due to over-irriga­ in tion, increased leaching of nutrients, in­ creased Poa annua invasion, increased water susceptibility, and generally reduced turf vigor and quality (1). A deficiency of water results in wilting, but ultimately leads to reduced Continued on Page 13 10 OUR GANG TO R O A u n iq u e m ow in g tra cto r, d e sig n e d to g ive m ore c u ttin g c a p a c ity to o n e m an and o ne m a c h in e .

The question then can be asked - How can the moisture content of the soil be determined in order to maintain optimum moisture in the soil? It would be well if we could “ Ask the plant.” In a sense this is done with some of the techniques practiced. For example, footprinting - when the grass will not spring back to its original position after walking on the turf - is an indica­ tion that the leaf is quite flaccid and wilt is imminent. if he An alternative One can also look for those tell­ tale spots which show the typical bluish-green color before wilt occurs. Such spots may be due to sandy soil or organism activity, or they may be areas which receive less irrigation. One must know his turf, soil, and irrigation system well is to depend on this approach. to “ Asking the plant” is to “ Ask the soil.” Visually examining a sample of the soil ob­ tained with a soil probe is one means of doing this. The ease with which a metal rod can be pushed into the soil, or some of the simple, inexpensive soil moisture sensors which can be pushed into the soil have been also used to estimate soil moisture. These are not particularly accurate, but with experi­ ence they may be helpful. The user must know the soil and turf conditions extremely well to use these techniques effectively. More sophisticated and expensive approaches utilize moisture blocks of tensiometers. Moisture blocks buried in the soil have wires to the surface which can be attached to a meter above the ground to make moisture measure­ ments. The moisture blocks operate most effectively in moisture ranges somewhat drier than the levels gener­ ally desired for putting green turf. A tensiometer may be defined as a water tension meter. A porous ceramic tip is attached to a plastic tube and buried in the rootzone of the turf. A gauge is connected to the top o f the tube which is sensitive to the tension 13 (or suction) on the water in the tube. Water moves freely through the ceramic tip, making this instrument sensitive to changes in water levels in the soil. As the soil becomes dry, some of the water moves out of the tube through the tip, causing a slight vacuum in the tube, raising the reading on the gauge. ceramic The tensiometer is probably the best measure of soil moisture tension from a root hair point of view. As soil becomes drier, the root hair cannot as easily obtain water from the soil, and this in higher readings on the tensiometer. The 15 to 25 centibar moisture tension reading is generally considered the best range for turf (3). is readily reflected The tensiometer is not presently used extensively by superintendents for determining moisture needs for turf, but it has proven a valuable research tool. This is illustrated in data ob­ tained at the University of California (4). Irrigation Program Applied Water used during year — inches 1. Same as nearby golf course..............43 2.

These data support the thesis that much turf is over-irrigated, especially on the higher quality turf found on many golf courses. A few turf managers are using tensiometers as a guide for irrigation in southern California, but there are some limitations in their use; location tensiometer with respect to of Next Page the variability in the soil or turf in a given turf area, depth of rooting, cost, problem with vandalism. The fact that the tensiometers must be removed from the soil each winter in the Midwest are important factors. Although there are limitations in the use of tensiometers under turfgrass conditions they are a valuable research tool. This research need not be re­ stricted to experiment stations, how­ ever. The inquisitive superintendent can use the tensiometer to learn more about the effectiveness of his own irrigation program. But, one must understand the capabilities and limita­ tions of the tensiometer before using the results to change the irrigation program. Finally, as root hairs absorb water, small localized drier areas occur. At reduced water tension, capillary water movement may equalize (say over night) but at medium and drier soil the water around root tips may be readily depleted. Thus, leaf wilt indicates root tip need. In response, two things normally occur - we repeatedly water to avoid possible stress. And we apply much more than just replacement water. The active root tip and its root hairs are the water crew for the entire plant. Keeping them supplied with (internal) energy, outside air (oxygen), plus available water, is the challenge.

I read it with great interest and am passing it on to you. — Ted Woehrle MATHEMATICAL CUP PLACEMENT Recently I was proudly showing a friend of mine who happens to be a high school mathematics teacher the system that I had devised for cup and tee place­ ments. In my system I had the cup and tee locations all written down on a set of score cards and one of these cards would be used each day to dictate where the cups should go on any given hole. I remarked to my calculating friend that my system worked pretty well but, that in order to determine whether the cups were being placed in the right spots I had to carry around a duplicate set of cards. And, as I explained fur­ ther, I seldomly remembered to take my set of cards with me and therefore had no way of checking on my employees cup changing procedures short of stop­ ping at each green and carefully in­ specting it to determine where the cup had been the day before. This problem intrigued my friend so much that he went home and worked into the wee hours of the morning de­ vising the following plan that I found taped to my front door the following morning. 15 CALL LAKESHORE COLLECT (216) 651-1600 FOR ALL YOUR TURFGRASS SUPPLIES - QUOTATIONS ON REQUEST - - CHECK OUR PRICES ■ LAKESHORE E Q U IP M E N T & S U P P L Y CO. 1 0 2 3 7 B E R E A R O A D C L E V E L A N D , O H I O 4 4 1 0 2 YOU’ RE E N TITLE D TO THE BEST golf course CHEMICALS (You’ll get it • and more!)

Next find the remainder upon divid­ (the date) ing the following sum by six (6): (the month) (the hole number) When dividing 0,1,2,3,4» or 5 by 6 use the idea that 6 goes into them zero times with a remainder of 0,1,2,3,4, or 5 (i.e. the number itself). Then place the cup in the region with that number. For example on June 6th the cup on the 14th green would be placed in position #2 because 6 (June is the 6th month) plus 6 (the 6th day) plus 14 (the number of the hole) equals 26 and 26 divided by 6 equals four with a remainder of 2. Therefore, the cup goes into the position labeled #2. to This would cause your pin place­ ments jump two positions when changing from a 30 day month to the next month. When changing from a 31 day month the cycle would continue undisturbed. Example 1. (using the 7th hole) June 30th (6+30+7) + 6 July 1 (7+1+7) + 6 position #1 position #3 Example 2. (using the 7th hole) position #3 position #4 July 31 (7+31+7) + 6 August 1 (8+1+7) + 6 When I first read through this method I thought my friend had blown a fuse in his master computer but, the more I think about it, the better it sounds. After all, when you are accosted by an irate golfer who wants to know if you are aware of where the %#$#%$ cup is placed on one of your greens wouldn’t it be nice to be able to make some quick calculations and tell him exactly where it’s at? And wouldn’t it also be nice to be able to glance at a green and be able to tell immediately if your cup changer has put the cup in the right location?

Almost all trees are showing feeding. Severe cases resemble mite damage with mottled and speckled leaves. On many trees new growth is severely damaged. Shaking of branches on small trees will detect the presence of these sucking insects. Several instars, from small pale green to the adult which is green with black wing covers, are on the trees now. CONTROL: Spray with 2T/gal. 50% w.p. Sevin. Thorough coverage of leaves and twigs is essential for good control. Don’t spray when temperature will be likely to rise above 80 degrees for 2 hours after application. Malathion or Diazinon also will control these insects. C o o le y Spruce G a ll A p h id This small insect causes conelike galls on the tips of the branches of Colorado Blue and Engelman spruce. The young are present at this time on the needles of both spruce and Douglas fir and are susceptible to insecticides. CONTROL: Galls may be picked from spruce and burned, later, while they are still green. Spraying is effective at this time against the young feeding on the needles on both blue spruce and Douglas fir. Spray with 2 t./gal. of either 25% Diazinon emulsion or 50% Malathion emulsion. Meta-Systox-R may also be used, following label directions for aphids.
