Abstract/Contents: | "The lawn consisted primarily of fine leafed fescue. Treatment plots were 5 X 6 ft, arranged in a randomized complete block design and 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 sq ft. 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, the following soil and environmental conditions existed: air temperature, 88F; soil temperature, 82F; RH, 60%; amount of thatch, 0.5 inches; soil type, silt loam; soil size characterization, 23.2% sand, 60.6% silt, 16.2% clay; soil moisture, 24.6%; soil pH 5.3; organic matter, 3.9%; water pH, slightly acidic; 0.8 inches of rainfall was recorded over the posttreatment period. Posttreatment counts were made 28 Jul, 7 days after the initial treatment. 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. Three floatation samples were randomly taken from each replicate, and the total number of chinch bugs from each sample was recorded and converted to a sq-ft count. An average of 62 hairy chinch bug nymphs and adults/sq ft was recorded 21 Jul before treatment. Posttreatment counts completed on 28 Jul showed that all products provided significant control. No phytotoxicity was recorded." |
