| Abstract/Contents: | "Application of insecticides to turfgrass targeted for control of surface feeding herbivores could have an impact on subsequent white grub populations if and when they occur. In this study halfenozide formulations were applied at rates recommended and likely dates for control of surface pests. The treated checks were timed for white grub control. The study was located on a lawn of the Ohio Agricultural Research and Development Center at Wooster, Ohio. Applications were made on 17 Jun, 21 Jul, and 12 Aug to plots 3 x 5 ft arranged in a RCB replicated three times. Treatments were applied with a CO₂ sprayer and TeeJet XR8010VS nozzles at 30 psi pressure that delivered a volume of 2 gal/1000 ft². The treatments received no post-treatment irrigation. The site conditions were: 100% Kentucky bluegrass, no thatch, and the ground was level. Environmental conditions for the 17 Jun treatments were as follows: JB larvae-none present; turf-dry, 2.75 ht; soil-moist, 78°F at 1 inch and 76°F at 3 inch; weather-cloudy, 78°F, and 0-5 mph wind. Environmental conditions for the 21 Jul treatments were as follows: JB larvae -1st instars present; turf-dry, 3 inch ht; soil-moist, 77°F at 1 inch and 77°F at 3 inch; weather-cloudy, and 10-25 mph wind gusts. Environmental conditions for the 12 Aug treatments were as follows: JB larvae - 2nd instars presents; turf-dry, 2.75 inch ht; soil-moist, 75°F at 1 inch and 3 inch; weather-sunny, 76°F, and 3-8 mph wind. A caging technique was used to ensure JB ovipostition into the plots. Three cylinders, 8 inch diam x 6 inch ht each, were inserted into the plots. Thirty JB adults, measured volumetrically, were placed twice in each cylinder on 2 Jul (60% females) and on 7 Jul (52% females). Caged adults were fed fresh apple slices coated with brewers yeast every 2 days. Cylinders were removed 14 days after the intial caging. Efficacy data taken 7 Oct were based on the number of live larvae in three samples 8 inches in diam centered in the cage-cylinder locations of each plot. ANOVA was done on plot totals and means separated by LSD test at P = 0.1. All halofenzide formulations produced significant and acceptable reduction of the JB grubs at all treatment dates and split applications. The treated check Merit 75WP also gave significant excellent control when applied 17 Jun and 21 Aug. No phytotoxicity was observed." |
