Abstract/Contents:"This study was located on the lawns of the Ohio Agricultural Research and Development Center at Wooster, Ohio. Applications were made 16 May, 19 Jun, and 18 Aug to plots 3 x 5 ft arranged in a RCB design replicated three times. Treatments were applied with a CO₂ sprayer and Teejet^D]T^D]M 8015 nozzles at 60 psi pressure that delivered a volume of 3 gal/1000 ft². The site conditions were: 100% Kentucky bluegrass, 0-1/4 inch loose thatch, level. Environmental conditions at the time of the 16 May treatment were as follows: JB larvae - none present; turf - dry, 2 1/4 inch ht; soil - moist, 52°F at 1 inch and 51°F at 3 inch; weather - mostly sunny, 51°F, 0-1 mph wind. Environmental conditions at time of the 19 Jun treatments were as follows: JB larvae - none present; turf - dry, 2 1/4 inch ht; soil - moist, 72°F at 1 inch and 70°F at 3 inch; weather - sunny, 51°F, 0-3 mph wind. Environmental conditions at time of the 18 Aug treatments were as follows: JB larvae - none present; turf - dry, 2 1/4 inch ht; soil - moist, 72°F at 1 inch and 70°F at 3 inch; weather - mostly cloudy, 78°F, no wind. A caging technique was used to ensure JB oviposition into the plots. Three cylinders (8 inch diam by 6 inch ht) were inserted into the plots. Thirty JB adults, measured volumetrically, were placed and confined in each cylinder twice on 9 Jul (50%) and 15 Jul 54%). Caged adults were fed fresh apple slices coated with brewers yeast every 2 days. Cylinders were removed after 14 days of caging. Efficacy of treatment was evaluated on 1 Oct by recording the number of live larvae in three samples, each being 8 inches in diam, at the cylinder locations of each plot. ANOVA was done on plot totals and means separated by LSD test at P = -.05. All treatments at all application dates produced significant and satisfactory reduction of the JB larvae resulting from the caging process. No phytotoxicity was observed."
