Abstract/Contents:"Fifteen insecticide treatments were applied 26 Aug for control of Japanese beetle grubs. The driving range consisted of annual bluegrass (25%) and Kentucky bluegrass (75%). Treatment plots were 6 X 9 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied with a CO2 sprayer with four 8504 Tee Jet nozzles mounted on a 6-ft boom, operating at 35 psi with a 4 gal/1000 ft2 spray rate. Granular formulations were mixed with sand top-dressing to facilitate product distribution. Then they were applied with a hand-held shaker. At treatment time, the following soil and environmental conditions existed: air temp, 76 d F; soil temp at 1 inch depth, 75 d F; soil type, loam; soil pH, 4.8; % organic matter, 4.7; soil condition, dry; % soil moisture, 20.7; amt thatch, 0.25-0.75 inches; water pH, slightly acidic; % RH, 55; and clear sunny skies. A total of 0.8 inches of rain was recorded over the posttreatment period. Immediately after treatment, the entire plot was irrigated with 1/4 inch of water. Posttreatment counts were made 35 days later (30 Sept). Three ft2 sod samples were randomly taken from each replicate and the total number of surviving Japanese beetle grubs per ft2 was recorded 30 Sept. An average of 18.2 Japanese beetle grubs per ft2 was recorded 26 Aug before treatment. Posttreatment results showed that all formulations provided significant control. No phytotoxicity was noted."
