| Abstract/Contents: | "This study was conducted to compare different formulations of chlorantraniliprole and imidacloprid for the preventive control of JB larvae in turfgrass. Testing was done in a turf plot maintained at the NYS Agricultural Experiment Station (Geneva, NY). The site had been renovated and reseeded to perennial ryegrass in May, and maintained at a mowing ht of 3.5-4 inches. Evaluation units were PVC arenas (diameter 12 inches, depth 4 inches) placed in the ground so that the upper lip was level with the soil surface. Arenas were arranged in a RCB design with eight repetitions of seven treatments. Infestations were made by enclosing 15 male and 15 female JB adults over each ring for 7 days of mating and oviposition. Treatment applications were made 22 Jul 2008 followed by infestations on 29 July 2008. Liquid formulations were applied with a pressurized CO2 sprayer coupled with a single nozzle spray wand and a Teejet 8002VS flat fan tip. Granular formulations were evenly applied using a shaker jar. Conditions at time of application were the following: skies partly sunny; wind negligible; air temp 74.0°F; soil temp at 2-inch depth 75.0°F. Until the study was rated, rainfall was supplemented with 0.25 inches irrigation if 5 consecutive days lapsed with <0.10 inches rain on any of those days. Mean daily precipitation was 0.14 inches; mean daily air temp (min/max) 50.5/70°F; and mean daily soil temp at 2-inch depth (min/max) 54.5/82.5°F. JB larval populations were evaluated on 2 Oct 2008 by destructively searching the soil in each arena. Data were transformed by log(x+0.5) before ANOVA, followed by LSMeans separation using Student's t. Artificial infestations produced a mean population of 7.3 JB larvae/ft2 in the untreated check. All insecticidal treatments significant suppressed JB larvae with respect to the untreated check. Although there were significant differences among insecticidal treatments, this only ranged from 81.5 to 96.3% control. There was no discernible rate response for low and high rates of Acelepryn 1.67SC or E2Y45-401. Under the conditions of this study, where application preceded infestation, products may have operated as oviposition deterrents as well as larval mortality agents." |
