| Abstract/Contents: | "Conventional insecticides and entomopathogenic nematodes were evaluated for control of bluegrass billbug larvae on a Kentucky bluegrass lawn at the University of Nebraska Agricultural Research and Development Center near Mead, NE. The turf (100% Kentucky bluegrass) was maintained at a mowing height of 3 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 adequate throughout the study. Plots were 6 X 6 ft and the experimental design was a RCB with 4 replications. Treatments were applied on 10 Jul 1994. Granular insecticides were applied with a pre-calibrated 24H12 Gandy spreader. Liquid insecticides and nematodes were applied using a CO₂ sprayer with an Lf-4 nozzle at 30 psi and delivering 5 gal finished spray/1000 ft². Following applications, plots were irrigated with 0.5 inches of water. A total of 0.76 inches of rain fell during the post treatment period. Treatments were evaluated 15 DAT (25 Jul) by removing from each plot five, 6-inch diam turf-soil cores (0.98 ft² total area) to a depth of 3 inches and counting the number of surviving billbug larvae and pupae. Estimate of life stages at the time of application were mid to late instar with 30% pupae. Sevin 80WSP and Triumph 4E were the only treatments to provide statistically significant reductions of billbugs when compared to the untreated check. However, both rates of Fipronil, and the Biosafe nematodes provided numerical reductions in billbug numbers. No phytotoxicity was observed." |
