| Abstract/Contents: | "Grass clipping removal is a common practice in some turfgrass management systems. This study was primarily intended to investigate the impact of clipping removal overlaid with posttreatment irrigation and no irrigation on the efficacy imadacloprid and halofenozide applied for control of the JB prior to egg hatch. In addition, the influence of spray volume efficacy of a Beauveria bassiana formulation was evaluated. This field study was located on a lawn of the Ohio Agricultural Research and Development Center in Wooster, Ohio. Applications were made 23 and 29 Jun prior to egg laying, and 21 Jun after egg hatch to plots 3 x 5 ft arranged in a RCB, replicated three times. The 1 gal/1000 ft² spray volume treatments were applied with a CO₂ sprayer and TeeJet XR8006VS nozzles at 29 psi. For the 4 gal/1000 ft² spray treatments, TeeJet 8015 nozzles at 40 psi (2.81 kg/cm²) were used. The treated plots received 2.5 gal of water with a sprinkling can immediately after treatment. In order to prevent any post-treatment rainfall on the non-irrigated plots, they were covered with custom built polyproplyene tents whenever rainfall was imminent for a 7-day period. A combination bagging-mulching lawn mower was used for the clipping management two days after 23-Jun applications. Approximately one third of the grass clippings were either removed by bagging or returned to the plots by mulching. The site conditions were: 100% Kentucky bluegrass, 3 inch (7.6 cm) ht, dry, no thatch, and the ground was level. A caging technique was used to ensure JB oviposition into the plots. Three cylinders, 8 inch diam x a 6 inch ht, were inserted into the plots. Thirty JB adults, measured volumetrically, were placed and confined in each cylinder on 2 and 3 Jul (48% females) and on 9 Jul forty more adults (38% females) were caged. Caged adults were fed fresh apple slices coated with brewers yeast every 2 days. Cylinders were removed 14 days after the initial caging. The number of live larvae in three 8-inch diam samples centered on the cylinder-cage in each plot were recorded on 6 Oct. ANOVA was done on plot totals and means separated by LSD test at p = 0.1. All Mach-2 2SC (halfenozide) and Merit 75WP (imadacloprid) treatments gave more that 97 % control of JB larvae regardless of whether the clippings were removed or returned, and the plots were irrigated. It is notable that 2.55 inches of rainfall occurred within 7 days after the 23-Jun applications or the period when the non-irrigated plots were covered during these rains. The Naturalis T (Beauveria bassiana) treatment at 1 gal/1000 ft² spray significantly reduced the grub population, but an average of 10.8 per cylinder or 3.9/ft² survived 78 DAT. No phytotoxicity was observed." |
