| Abstract/Contents: | "The study was conducted in Lincoln, NE on a Kentucky bluegrass golf course fairway. The turf (100% Kentucky bluegrass) was maintained at a mowing height of 5/8 inches and thatch accumulation in the plot area was 0.75 inches (finger compressed, 0.5 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 40 inches x 15 ft and the experimental design was a RCB with 4 replications. Formulations were applied 24 Aug using a Cushman Prototype Subsurface Applicator configured to place liquid formulations at the soil-thatch interface (average depth, 0.75 inches). Immediately following the applications, plots were irrigated with 0.5 inches of water. A total of 5.41 inches of rain fell during the post-treatment period. 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 number of surviving grubs. Pretreatment counts indicated 20-80 SMC [southern masked chafer] grubs (1% eggs, 80% first-instar, 18% second-instar, 1% third-instar) per square foot. All treatments resulted in statistically significant reductions in white grub numbers even in the presence of 0.5 to 0.75 inches of thatch. Triumph provided greater than 95% control. No phtotoxicity was observed." |
