| Abstract/Contents: | "Treatment plots were 5 X 6 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied 23 July by using a CO2 sprayer with four 8504 Tee Jet nozzles mounted on a 6-ft boom, operating at 35 psi with a 5 gal/1000 ft2 spray rate. Granular formulations were mixed with sand top-dressing to facilitate product distribution. Then they were applied with a hand held shaker. Immediately after treatment, each replicate was syringed with 1 gal of water. At treatment time, the following environmental conditions existed: air temp, 90 d F; soil temp at a 1-inch depth, 86 d F; soil type, loam; soil pH, 5.0; % organic matter, 2.5; soil condition, dry; % soil moisture, 5.8; amt thatch, 0.25-0.5 inches; water pH, slightly acidic; % RH, 85; and clear sunny skies. A total of 1.75 inches of rain was recorded over the posttreatment period. Posttreatment counts were made 7 days after the initial 23 July treatment date. Hairy chinch bugs were sampled by driving a 6 inch open ended stainless steel cylinder into the turf, filling with water, and counting the number of chinch bug nymphs and adults floating to the surface over a 10-minute period. Three floatation 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 66.1 hairy chinch bug nymphs and adults per ft2 was recorded 23 Aug before treatment date. Posttreatment counts completed on 29 Aug showed that all formulations provided significant control. No phytotoxicity was noted." |
