| Abstract/Contents: | "This study was conducted 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 2.5 inches. Thatch accumulation (finger compressed) in the plot area was 0.50 inches. Field conditions at the study site were: soil type, silty clay loam; soil organic matter, 3.5%; soil pH, 6.2-6.6; water pH, 7.0. Environmental conditions at the times of application, (13 May, 22 Jun, and 1 Jul) were as follows: soil moistures by wt 15%, 20%, and none, respectively; air temperatures 84°, 79°, and 81°F; soil temperatures 74°, 75°, and 86°F; relative humidities 52%, 64%, and 50%; wind directions and velocities 144° at 19 mph, 192° at 5 mph, and 85° at 4 mph. Plots were 6 ft x 10 ft and the experimental design was a RCB with four replications. Liquid insecticides were applied using a CO₂ sprayer with a TeeJet 8002 nozzle at 30 psi and delivering 87 gpa formulations. Plots were irrigated with 0.125 inch of water following application. Post-treatment precipitation totaled 11.21 inches. Treatments were evaluated 10 Jul (58, 18, and 9 DAT) by by removing three, 8-inch diam turf-soil cores (1.05 ft² total area) to a depth of 3 inches and visually examining the soil and thatch for surviving billbug larvae. All products, regardless of application date, provided statistically significant reductions in BB numbers when compared to the untreated control. Mach 2 applied early (May) and mid-season (June) provided numerically higher reductions in billbug larvae than the late season application. No phtotoxicity was observed." |
