| Abstract/Contents: | "The study was conducted on the Ohio State University Agricultural and Techincal Institute fron lawn at Wooster, OH. Insecticides and a biological control agent were applied on 2 Jul to plots 4 X 6 ft arranged in a RCB design, replicated 4 times with the replicates separated by 3 ft. Spray treatments were applied using a CO₂ sprayer with TeeJet^D]T^D]M 8004VS nozzles at 25 psi pressure that delivered a volume of 3.1 gal/1000 ft². Granular treatments were applied using a shaker jar. Entomopathogenic nematodes were applied by placing the desired amount of infected juveniles per plot into a sprinkling can with 2.0 gal of water. All treatments were irrigated after application with 3/8-inch of water immediately after application. Environmental conditions at the time of treatment were as follows: Turf: slight slope, moderately dense, 3-inch height, surface dry, 80% Kentucky bluegrass and 20% perennial ryegrass. Thatch: none. Soil: dry, 85°F at 1.0 inch, 83°F at 3.0 inch, clay loam. Weather: partly cloudy, 83°F, 5-15 mph wind. Evaluation was done on 16 Aug (14DAT) by counting the number of BGB larvae and pupae extracted from four 4.25-inch diam turf and soil cores pulled from each plot. Each core was pulled from a spot where a BGB frass-filled turf stem was detected. All the treatments, except Astro 3.2EC (0.8 lb[AI]/acre) and Bifenthrin 0.5G, were equally effective in reducing the BGB larval and pupal population density below that in the untreated check." |
