| Abstract/Contents: | "Twenty insecticide treatments were applied 20 Aug for control of Japanese beetle grubs. The golf course turf consisted primarily of annual bluegrass (80%) and crabgrass (20%). Treatment plots were 6 X 9 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied 20 Aug 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 topdressing to facilitate distribution. Then they were applied with a hand held shaker. At treatment time, the following soil and environmental factors existed: air temp, 85 d F; soil temp at 1 inch, 73 d F; soil type, silt loam; soil pH, 5.8; % organic matter, 3.9; soil condition, dry; % soil moisture, 13.4; amt thatch, 0.25-1.00 inches; water pH, slightly acidic; %RH 70; and clear sunny skies. A total of 2.7 inches of rain was recorded over the posttreatment period. Immediately after treatment, each replicate was individually watered-in with 1/4 inch of water. Posttreatment counts were made 34 days later (23 Sept). Four ft2 sod samples were randomly taken from each replicate and the total number of Japanese beetle grubs per ft2 was recorded 23 Sept. An average of 18.2 Japanese beetle grubs per ft2 was recorded on 20 Aug before treatment. Posttreatment results indicate all treatments provided significant control. No phytotoxicity was noted." |
