| Abstract/Contents: | "This study was conducted at the University of Nebraska Agricultural Research and Development Center near Mead, Nebraska. The turf (100% creeping bentgrass) was maintained at a mowing height of 0.625 inch., Thatch accumulation (finger compressed) in the plot area was 0.50 inch. Field conditions at the study site were: soil type, silty clay loam; soil organic matter, 3.5%; soil pH, 6.5; water pH, 7.0. Environmental conditions at the time of application, (09 Jul) were as follows: soil moisture 20% by wt; air temperature 82°F; soil temperature 82°F; relative humidity 82%; wind direction and velocity 123° at 8 mph. Each 1 x 8 ft plot contained three 8-inch-dia. artificial infestation pots and the experimental design was a RCB with 4 replications. Plot area was treated with Sevin to two weeks prior to cutworm introduction to reduce potential predators. Bentgrass sod was installed one week prior to cutworm inoculation to promote turf establishment. Twenty 0.5- to 0.75-inch-long cutworms were placed into each infestation plot 1 d before insecticide application. Liquid insecticides were applied using a CO₂ sprayer with a TeeJet® 8002 nozzle at 30 psi and delivering 87 gpa. Plots were not irrigated for 24 h. Post-treatment precipitation totaled 0.24 inches. Treatments were evaluated 1, 3, and 7 days after application. Dursban Pro consistently provided statistically significant reductions of BCW numbers at all evaluations dates as compared with the untreated check. At 1 DAT, the lower rates of NAF 313 and NAF 379 and all high rates of the NAF products except NAF 379 provided significant BCW reductions. All products provided statistically significant reductions of BCW at 3 DAT with high rates providing a greater percent control. By the end of the study at 7 DAT, all products except NAF 381 and NAF 380 attained 100% control. No phytotoxicity was observed." |
