| Abstract/Contents: | "Three formulations of Mach-2 insecticide applied on 2 application dates (May and Jun) were evaluated for control of bluegrass billbugs in plots located at the University of Nebraska Agricultural Research and Development Center near Mead, Nebraska. The turf (100% Kentucky bluegrass) was maintained at a height of 3 inches. Thatch accumulation (finger compressed) in the plot area was 0.5 inch. Field conditions at the study site were: soil type, silty clay loam; solid organic matter, 3-5%; soil pH, 6-7; water pH, 7.0. Environmental conditions at the time of treatment were as follows: soil moisture 24% on both dates; air temp 63°F and 59°F, respectively; soil temperature 65°F and 62°F; relative humidity 63% and 75%; wind direction and velocity 339° at 16 mph and 43° at 7 mph. Plots were 6 x 10 ft and the experimental design was a RCB with 4 replications. Insecticide treatments were applied on 24 May and 16 Jun 1999 using a CO2 sprayer with a TeeJet® 8002 nozzle at 30 psi and delivering 87 gpa formulation. Post treatment irrigation was 0.125 inch. A total of 7.0 inches of rain accumulated during the post treatment period. Treatments were evaluated 45 and 22 DAT (8 Jul) by removing from each plot three, 8 inch diam turf-soil cores (2.10 ft2 total area) to depth of 3 inches and counting the number of surviving larvae. The pre-treatment estimate of insect activity was approximately 1 billbug adult per ft2. All treatments provided statistically significant reductions in the number of billbug larvae regardless of formulation and application timing when compared to the untreated check. Although not significant, there was a general trend toward better control with the 0.86FG formulation applied on 16 Jun. No phytotoxicity was observed." |
