| Abstract/Contents: | "The turfgrass area consisted primarily of fine leafed fescue in Somerset, PA. Treatment plots were 4 x 6 ft arranged in a RCB design and replicated 3 times. Liquid formulations were applied by using a CO₂ compressed air sprayer with 4 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and applied in 182 ml of water/24 ft² or delivering 2 gal/1000 ft². At treatment time (31 Jul) the following soil and environmental conditions existed: air temperature, 74°F; soil temperature at 1 inch depth, 70°F; soil temperature aat 2 inch depth, 69°F; RH, 73%; amount of thatch, 0.75 inch; soil textural class, loam; soil particle size analysis: 34.4% sand, 48.7% silt, 16.9% clay, soil moisture (oven dry weight), 24.1%; organic matter, 5.5%; water pH, 7.0; soil pH, 5.2; application time, late morning; and overcast skies. Hairy chinch bugs were sampled by driving a 6-inch diam stainless steel cylinder into the turf, fiilling it with water, and counting the number of chinch but nymphs and adults floating to the surface during a 10 min period 6 DAT (6 Aug) and 14 DAT (14 Aug). Two flotation samples were taken randomly from each replicate, and the total number of chinch bugs from each sample was recorded and converted to a ft² count. An average of 73 hairy chinch bug nymphs and adults/ft² was recorded 31 Jul before treatment. Post-treatment counts on both sampling dates indicated that all treatments provided significant control. No phytotozicity was noted." |
