| Abstract/Contents: | "This study was conducted in summer 2008 to evaluate preventative and curative applications of Arena (clothianidin) for control of white grubs in bermudagrass turf. Treatments were applied to a bermudagrass fairway located at a demonstration golf course at the Oklahoma State University Oklahoma City campus. Plots were 6 ft by 8 ft (48 ft2) and mowed at 0.5 inch and irrigated as needed. Treatments consisted of both preventative (early) and curative (late) applications of Arena 50WG and Arena 0.25G (four treatments). Preventative applications of Merit 0.25G, Merit 0.5G, Hi-Yield Grub Free Zone, and Allectus GC SC were also included as standard white grub treatments. All treatments were compared against a non-treated control group and replicated 4 times in a randomized complete block design. Treatments were made at mid-morning on Jun 3, 2008 (early treatments) and Jul 18, 2008 (late treatments). Granular treatments were applied by hand evenly across plots and liquid treatments were applied with a CO2 pressurized (18 psi) wheelbarrow sprayer equipped with four TX8008 flat fan nozzles and calibrated to deliver 2.0 gal/1000 ft2. All plots were irrigated with approximately 0.25 inch of water following insecticide application. Grub populations were determined on Oct 9, 2008 by sampling 9 ft2 lengthwise at the center of each plot using a mechanical sod cutter measuring 1.5 ft wide and set at a depth of 2.0 inches. The turf and soil from each plot were examined to determine the number of white grubs. All data were log(x+1) transformed and analyzed using ANOVA (SAS 9.1, PROC GLM). White grub densities were quite variable among plots. Non-treated control plots had the highest variability in white grub densities, ranging from 0.0 to 8.3 grubs per ft2. A large no. of plots did not have grubs, especially among the Arena treatments. Thus, the data were not normally distributed even after transformation and could not be analyzed with parametric statistics. Nevertheless, a clear numerical trend was evident based on the mean no. of white grubs per ft2 (Table 1). On avg, control was successful for all treatments with white grub densities remaining below established treatment thresholds for phyllophaga spp. and Cyclocephala lurida. The non-treated control plots had the highest white grub densities on average, though these densities were also below treatment thresholds. All four Arena treatments led to large reductions in white grub densities with preventative or curative applications of Arena 0.25G performing better than those of Arena 50WG. Plots treated with granular imidacloprid products had greater than 65% reduction in white grub populations compared to the non-treated control plots. Allectus GC SC, which contains both imidacloprid and bifenthrin, only reduced white grub populations by approximately 40%. Phytotoxicity was not observed during the growing season for all treatments." |
