Abstract/Contents:"Twenty insecticide treatments were applied 4 Sep for control of Japanese beetle grubs. The fairway consisted of annual bluegrass (50%), Kentucky bluegrass (20%), and perennial ryegrass (30%). Treatment plots were 6 by 9ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied by using a compressed air sprayer with four 6504 Tee Jet nozzles mounted on a 6-ft boom, operating at 25 psi with a 3 gal/1,000 ft2 spray rate. Granular formulations were applied with a hand held shaker. After all treatments were completed, the entire area was irrigated for 20 min. At treatment time, the following soil and environmental conditions existed: air temp at 1-inch depth, 72 degrees F; soil temp at 2-inch depth, 68 degrees F; soil type; silt loam; soil pH, 7.2; % organic matte 5.0; soil condition, moist; amount of thatch , 0.90625 inches; and partly cloudy skies. Posttreatment counts were made 38 days later (Oct 11). Four ft2 sod samples were taken from the center of each replicate and the total number of surviving Japanese beetle grubs was recorded for each ft2 sample. An average of 30 grubs per ft2 was recorded 4 Sep before treatment. Posttreatment results showed that all formulations provided significant control except Dursban 4E and UC76721 25EC. No phytotoxicity was noted."
