| Abstract/Contents: | "The study was conducted in Lincoln, NE on a Kentucky bluegrass golf course rough. The turf (100% Kentucky bluegrass) was maintained at a mowing height of 1.5 inches and thatch accumulation in the plot area was 0.5 inches (finger compressed, 0.25 inches). Field conditions at the time of application were: soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6-7; water pH, 7.0; soil moisture, near field capacity. Plots were 6 x 6 ft and the experimental design was a RCB with 4 replications. Insecticide treatments were applied 24 Aug using a CO2 sprayer with an LF-4 tip at 24 psi and delivering 5 gal finished spray/1000 ft2. Immediately following applications, the test area was irrigated with approximately 0.5 inches of water. A total of 4.61 inches of rain fell during the post-treatment period. Product efficacy was evaluated 14 Sep (21 DAT) by removing from each plot three 8-inch diam turf-soil cores (1.02 ft2 total area) to a depth of 3 inches and counting the number of surviving grubs. Pretreatment counts indicated 100-125 SMC [southern masked chafer] grubs (5% eggs, 85% first-instar, 10% second-instar, 15% third-instar) per square foot. All treatments provided statistically significant reductions in white grub numbers when compared to the untreated check. An addition of the wetting agent HM8902 did not seem to enhance white grub control. This may have been due in part to the 4.6 inches of rain that fell during the post-treatment period. No phytotoxicity was observed." |
