| Abstract/Contents: | "The turfgrass area consisted primarily of fine leafed fescue. Treatment plots were 5 x 6 ft arranged in a randomized complete block design, 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 340 ml of water/30 ft² or delivering 2 gal (1000 ft²). At treatment time (2 Aug) the following soil and environmental conditions existed: air temperature, 79°F; soil temperature at 1 inch depth, 90°F; soil temperature at 2 inch depth, 82°F; RH, 70%; amount of thatch, 0.75-1.5 inches; soil textural class, loam; soil particle size analysis: 33.5% sand, 48.3% silt, 18.2% clay; soil moisture (oven dry weight), 9.5%; organic matter, 6.5%; water pH, 7.0; soil pH, 5.9; application time, late afternoon; and overcast skies. Immediately after treatment the experimental area was irrigated with 0.1 inch of water. Hairy chinch bugs were sampled by driving a 6 inch-diam stainless steel cylinder into the turf, filling it with water, and counting the number of chinch bug nymphs and adults floating to the surface during a 10 min period (sampling dates: 8, 17, 30 Aug). Three flotation samples were taken randomly from each replicate, and the total number of chingh bugs from each sample was recorded and converted to a ft² count. An average of 90.3 hairy chinch bug nymphs and adults/ft² was recorded 2 Aug before treatment., Posttreatment counts completed on all three sampling dates indicated that all treatments provided significant control. No phytotoxicity was noted." |
