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 sprayer with 4 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and delivering 5 gal/1000 ft2. Granular formulations were applied with a hand-held shaker and mixed with a fine grade of top dressing sand to facilitate product distribution. At treatment time (30 Jul) the following soil and environmental conditions existed: air temperature, 70° F; soil temperature at 1 inch depth, 68° F; soil temperature at 2 inch depth, 68° F; RH, 30%; amount of thatch, 0.5 inches; soil type, silt-loam; soil particle size analysis: 18.0% sand, 67.0% silt, 15.0% clay; soil moisture (oven baked), 31.3%; organic matter, 3.5%, water pH, 7.0; soil pH, 5.6; and cloudy skies. Immediately after treatment the experimental area was irrigated with 0.25 inches 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 15 min period. Three 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 126.5 hairy chinch bug nymphs and adults/ft2 was recorded 30 Jul before treatment. Posttreatment counts completed on 6 Aug indicated that all treatments provided significant control. No phytotoxicity was noted."
