Abstract/Contents:"This study was conducted in Lincoln, NE on a golf course fairway. The turf (50% Kenyucky bluegrass and 50% perennial rye) was maintained at a mowing height of 11/16 inches. Thatch accumulation (finger compressed) in the plot area was 0.375 to 0.50 inches. Field conditions at the study site were: soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6.7; water pH, 7.0. Environmental conditions at the time of application were as follows: soil moisture 21%; air temperature 78°F; soil temperature 83°F; relative humidity 64%; wind direction and velocity 31° at 6 mph. Plots were 40 inches x 15 ft and the experimental design was a RCB with 4 replications. Insecticide applications were applied on 9 Aug 1995 using either a Cushman prototype subsurface applicator designed to place insecticide granular treatments at the soil-thatch interface (avg depth 0.5 inches), or a CO₂ sprayer with an LF4 nozzle at 40 psi and delivering 3 gal/1000 ft². Following applications, plots were irrigated with 0.25 inches of water. Post-treatment precipition totaled 0.67 inches. Treatments were evaluated 28 DAT on 6 SEP by removing from each plot three, 8-inch diam turf-soil cores (1.05 ft² total area) to a depth of 3 inches and counting the number of surviving grubs. Pretreatment counts indicated 10-20 SMC/ft² with 18% eggs and 82% second instars in the test area. Turcam 76 WP at the 3.0 rate was the only product to significantly reduce the white grub numbers when compared to the untreated control. However, both Ru58753 10 WP at the 0.11 rate and Cruiser at the 600 million/ac rate achieved greater than 70% control regardless of the application method. No phytotoxicity was observed."
