| Abstract/Contents: | "The study was conducted on a buffalograss lawn in Lincoln, NE. The buffalograss was maintained at a mowing height of 10 cm and was mowed to 5 cm prior to insecticide applications. Thatch accumulation ranged from 0 to 0.64 cm. Conditions at the time of application were as follows: air temperature, 26 degrees C; soil temperature (10-cm depth), 26 C; soil type; silty clay loam; soil organic matter, 3-5%; soil pH, 6.0 to 7.0; water pH, 7.0; soil moisture, near field capacity. Insecticides were applied on 4 Jun to 1.2 X 1.2 m plots arranged in a RCB with 5 replications. Insecticides were appplied with a CO2 sprayer using a LF-4 nozzle at 165.5 KPa and delivering 18.9 liter spray/93 m2. Immediately following application, plots were syringed with 0.32 cm water. Product efficacy was evaluated 5 DAT (9 Jun) and 14 DAT (18 Jun) by removing from each plot three turf-soil cores to a depth of 2.54 cm with a 10.8 cm diam cup cutter (0.03 m2 total area per plot). Cores were returned to the laboratory and placed in Berlese funnels. Extracted chinch bugs were counted after 48 h. Pretreatment estimated indicated 80-100 chinch bugs per 0.03 m2 (84% first and 12% second instar, and 4% adults from the previous generation) in the test area. By 5 DAT, Dursban Turf, 43178F/17 at 0.25 kg (AI)/hectare, and WRC928-12356 at 0.07 kg (AI)/hectare had provided statistically significant reductions in chinch bug numbers when compared to the untreated check. After 14 days, Exhibit #25 at both the 1.0 and 0.5 billion/hectare rates and WRC9028-12356 at 0.023 kg (AI)/hectare had also provided significant chinch bug control. No phytotoxicity was observed." |
