NORTHEASTERN AGRONOMIST TAYLOR No. 1 April, 1957 "SOMETHING NEW" Your Turf letter has a new look; it is now the Eastern Turfletter, and is the result of a merger of the Mid-Atlantic and Northeastern Turfletters. We feel this merger will work out to the best interests of all concerned, as we will now have three Staff writers contributing to one publication, bringing you highlights of turf news from throughout the Region. Henceforth, the Eastern Turfletter will be mailed to all subscribers in the Mid-Atlantic and Northeastern areas in place of the individual Turfletters formerly published by these two offices. This is YOUR Turfletter, and your suggestions for improvement are always welcome. "SOMETHING OLD" Our "old friends" of the insect world were more in evidence last It seemed to us fall in parts of the Mid-Atlantic and Northeastern areas. that there was also a great deal of renewed interest in insecticides at several recent conferences and local meetings; therefore we feel that a review of some insect control practices are in order. There are many excellent insecticides presently on the market. A few of the more common ones used by turf men are lead arsenate, Milky Spore, DDT, Chlordane, Dieldrin, Aldrin, and Heptachlor. The first three mentioned were the first to be used in combating Japanese beetles and other beetle grubs in the earlier days of severe infestation; the latter-mentioned chemicals are of the newer, and quicker acting class of chlorinated hydrocarbons developed in recent years. There are many commercial formulaters, and several different formulations of insecticides presently used. consider carefully the strength of the material purchased, and to use it at the rate recommended for the specified insect in question. It is important therefore to Insecticides recommended for turf use are generally compatible with fertilizers, and it is sometimes possible to have a mixture made up to your specifications by some fertilizer concerns. Chlordane is not compatible .with lime, but Aldrin, Dieldrin, and Heptachlor can be used safely mixed with lime.

The dye material clearly paints the pattern of each individual nozzle that you can expect in applying insecticides (or any other spray treatment). The importance of uniformity cannot be overemphasized, for obvious reasons. The calibration of the spray equipment is also vitally important. An easy method suggested by Dr. R. J. Aldrieh and Dr. D. A. Schallock of Rutgers University is as follows! (1) Divide the width of the boom into 1*3,560 (square feet per acre.) (2) Measure off the distance (answer) obtained in step (1). (3) Fill the spray tank with water and spray the measured distance with tractor speed and sprayer set exactly as they will be when applying the chemical. (k) Measure the anount of water needed to refill the spray tank upon completion of step (3), and this is the number of gallons that are required to cover an acre with your equipment. These gentlemen also caution that if more than 20 gallons are applied to the acre, the spray pattern should be checked for uniform coverage. At higher gallonages, the capacity of the pump and the size of the fittings and boom may be inadequate, causing a pronounced drop in pressure between the pump and boom. If a drop in pressure is suspected, it is suggested than an additional pressure guage be placed in the system as near as possible to the boom. We Hear From Our Readers Some of our readers felt that the statement contained in the February, ,fThe prime consideration in pur chasing 1957 issue of the Northeastern Turf letter, fertilizer is the price per pound of nutrient" needed elaboration. We agree and add: In purchasing fertilisers, it is important to figure the cost of each nutrient, and compare prices of the various fertilizer analyses. Organic nitrogen generally is more costly than inorganic nitrogen. In turf culture, nitrogen Is the key nutrient to consider normally, as nitrogen plays the leading role in the fine turf field.
