| Abstract/Contents: | "Two turf insecticides were applied to golf course rough turf (maintained at 2.0 to 3.5 inches) on 30 May 2008 and sampled 8 Oct to determine the efficacy of the compounds against JB larvae. Compounds tested were: Acelypryn (chlorantraniliprole, a newly registered insecticide for use on turfgrass) and Merit (imidacloprid, a neonicotinoid long regarded as the industry standard for white grub control). E2Y45 is the code assigned to chlorantraniliprole by DuPont; three experimental formulations of E2Y45 were included in this trial. The test included four different formulations of chlorantraniliprole and three formulations of imidacloprid, and was conducted at Stockbridge Golf Club, Stockbridge, MA. The conditions at the time of application were as follows: air temp, 58° F ; soil temp, 53° F; water pH, 7.1; soil pH 7.3, buffered pH 7.2; CEC 16.7 Meq/100g; light overcast and calm. Treatment plots were 8 ft by 8 ft, replicated four times, and arranged in a CRB design. All sprayable formulations were applied with a watering can (3 qt water per plot). Granular products were applied by hand using jars with perforated lids. Plots were irrigated with 0.2 inch within 1 h after application. Product efficacy was evaluated on 8 Oct by inspecting (on site) five 4.25-inch diameter cores from near the center of each plot. Each core was recorded separately and all grubs were identified to species and stage of development on site. All counts were included in statistical analyses (Fisher's Protected LSD, 0.05). There were about 13 grubs per sq ft in the untreated plots, which is within the commonly accepted threshold population (10 to 15 larvae per sq ft). All treatments reduced insect populations significantly relative to the untreated check but the sprayable formulation of Merit failed to provide an agronomically acceptable level of control. (Turf managers normally aspire to achieve at least 70 to 80% control with turf insecticides.) Both of these active ingredients have demonstrated good control of white grubs when used preventively in previous trials, and this trial appears to provide further support of excellent preventive activity." |
