Abstract/Contents:"The study was conducted on a golf course fairway of Columbia Hills Country Club at Columbia Station in Lorain Co., OH. Insecticides were applied the evening of 30 Jul to plots 6 X 20 ft (1.8 X 6.1m) arranged in a RCB replicated four times. Treatments were applied with a CO² sprayer and Teejet™ XR8006VS nozzles at 29 psi (2.04 kg/cm₂) pressure that delivered a volume of 1 gal/1000 ft₂ (407 liter/ha). The experimental area received no post-treatment irrigation between applications and data acquisition. Emvironmental conditions at time of treatment were as follows: BCW - approximately 6/yd₂, various instars; turf - level, dry, ½ inch (13mm) ht, 100% creeping bentgrass, ¼ inch (6mm) thatch depth; soil - moist, 78°F at 1 inch (2.5 cm) and 79°F at 3 inch (7.6 cm); weather - mostly cloudy, 80°F, 0-10 mph (0-16 km/h). Counts of the BCW carcasses present on surface of each plot were recorded the morning following treatment approximately 12 hours after treatment. Evaluation was done on the morning of Aug 1, approximately 36 hours after treatment, by recording the number of BCW live larvae rlushed to the surface using a soap irritant drench of 30 ml Joy dishwashing detergent per 2 gal (7.6 liter) water in two 1 yd₂ (0.9 X 0.9m) areas in each plot. The number of cutworm carcasses the morning following treatment of the Tempo 20WP and Dursban Pro was significantly greater than in the other treatments. Dursban Pro plots had significantly more larvae than the Tempo 20WP plots. Efficacy of all treatments was significant 36 hours after treatment. No phytotoxicity was observed."
