| Abstract/Contents: | "The lawn consisted of perennial ryegrass (10%) and fine leafed fescue (90%). Treatment plots were 5 by 6 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied 10 Aug by using a compressed air sprayer with four 6504 Tee Jet nozzles mounted on a 6-ft boom, operating at 25 psi with a 3 gal/1,000 ft2 spray rate. Granular formulations were applied with a hand held shaker. At treatment time, the following soil and environmental conditions existed: air temp, 85 degrees F; soil temp at 1 inch, 79 degrees F; soil temp at 2 inch depth, 79 degrees F, 75 degrees F; soil type, silt loam, soil pH, 6.8; % organic matter, 2.4; soil condition, dry; amount of thatch, 0.5 inches; and partly cloudly skies. After all treatments were completed, the entire area was lightly syringed with water. Posttreatment counts were made 7 days later (17 Aug). Hairy chinch bugs were sampled by driving a 6-inch diam open ended steel cylinder into the turf, filling with water, an counting the number of chinch bug nymphs and adults floating to the surface over a 10-minute period. Three flotation samples were randomly taken from within each replicate, and the total number of chinch bugs from each sample was recorded and converted to a ft2 count. An average of 156 hairy chinch bug nymphs and adults per ft2 was recorded 10 Aug before treatment. Posttreatment counts completed on 17 Aug showed that all formulations provided significant control. No phytotoxicity was noted." |
