Abstract/Contents:"I am pleased to report that compounds such as DDT and Chlordane used for the control of grub populations in better turf in 1946 and 1947 respectively, would appear to be as efective in late summer 1951 as at the time the materials were applied to grub-infested fairways. Furthermore, compounds Aldrin, Dieldrin, Heptachlor and Methoxychlor are as effective in preventing the infestation by white grub populations such as Japanese beetle as during the seasons in which they were used, to wit: 1948, 1949 and 1950. Parathion, of course, loses it toxic properties very quickly, especially at lower dosages. Gamma Benzenehexachloride and Toxaphene applied to grub infested turf in 1947 have obviously lost some of their toxicity in preventing reestablishment of grubs in 1951. It is my pleasure to report that two new compounds are now being investigated for control of turf insects of both surface and sub-surface species. These compoundsare known only by code numbers - that is, 711 and 269. These two compounds have been developed by Julius Hyman Company, Denver, Colorado. They are reported by the manufacturer to be somewhat more toxic than Aldrin and Dieldrin and consequently may be used at lower levels than the latter two compounds. We have established research plots on one of the fairways at Wepawaug Country Club, Milford, Connecticut, using Compound 269 at the rate of 1/2, 1, 2, 10, 15 and 20 pounds of actual toxicant per acre; also compound 711 at the rate of 1/2, 1 and 2 pounds of actual toxicant per acre basis. Both materials have been applied to mixed grub populations, to wit: Japanese beetle and Asiastic Garden Beetle, together averaging about 5 to 6 grubs per square foot of fairway turf. We are, to say the least, enthusiastic about 711 and 269 for, as heretofore pointed out, the toxicants may be used, according to information available, at as little as one-half pound of actual chemical per acre to achieve fast action and long residual activity in control of turf inhabiting insects."
