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, 21 degrees C; soil temperature (10-cm depth), 21 degrees 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 17 Jun to 1.2 X 1.2 m plots arranged in a RCB design with 5 replications. Liquid insecticides were applied with a CO2 sprayer using a LF-4 nozzle at 165.5 KPa and delivering 18.9 liter spray/93 m2. Granular formulations were applied with a calibrated Grandy 24H12 spreader. Immediately following application plots were syringed with 0.32 cm of water. Product efficacy was evaluated 5 DAT (22 Jun) by removing from each three turf-soil cores to a depth of 1.3 cm with a 10.8 cm diam cup (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 estimates indicated 50-100 chinch bugs per 0.03 m2 (26% first, 28% second, 31% third, 12% fourth, 3% fifth instar) in the test area. All treatments resulted in statistically significant reduction in chinch bug numbers. High level reductions in chinch bug numbers. High level of control was likely achieved by treating early instars. 035711 2G, Dursban Turf at 0.45 kg, and 0.34 kg, FN-5354 4E at 0.23 kg, Pageant DF, and Dursban Turf 2.32G provided 98% or better chinch bug control. No phytotoxicity was observed." |
