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, Nebraska. The turf (100% Kentucky bluegrass) was maintained at a mowing height of 3 inches. Field condition 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 randomized complete block with 4 replications. Treatments were applied on 10 Jul 1994... 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. 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."
