| Abstract/Contents: | "This study was conducted in Lincoln, NE on a golf course fairway. The turf (100% Kentucky bluegrass) was maintained at a mowing height of 5/8 inches. Thatch accumulation (finger compressed) in the plot area was 0.5 to 0.75 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. Soil moisture was maintained at approximately 16% by weight, throughout the study. Plots were 40 inches X 15 ft and the experimental design was a RCB with 3 replications. Insecticide treatments were applied on 24 Aug 1994 using a Cushman prototype subsurface applicator designed to place liquid insecticide treatments at the soil-thatch interface (avg depth 0.75 inches). Following applications, plots were irrigated with 0.5 inches of water. Post-treatment precipitation totaled 0.42 inches. Treatments were evaluated 21 DAT on 14 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 no. of surviving grubs. Pretreatment counts indicated 10-40 SMC/ft² with 80-90% in the third instar stage in the test area. Turcam 76WP, Triumph 4E, Saga 40WP at the 0.04 rate, Talstar 1EC at 0.22 rate, and two experimental formulations, RU 58753 ISO 89RJ 10WP at the 0.04 rate and RU 58753 ISO 89RI 10CS at the 0.08 rate, provided statistically significant reductions in white grub numbers when compared to the untreated check. Numerically, Talstar 1EC and RU 58753 ISO 89RI 10CS seemed to show a rate response. Bird predation reduced white grub numbers in some plots. No phytotoxicity was observed." |
