| Abstract/Contents: | "This test was conducted on mature low-maintenance Kentucky bluegrass turf at the University of Kentucky Spindletop Farm, near Lexington. The turf was on a Maury silt loam soil (pH = 6.2) with negligible thatch. Plots (5 x 6 ft) were arranged in a RCB with four replicates. Natural infestations were augmented by inoculating all plots with ≅ 150 field-collected adult JB on 14-15 Jul. Beetles were enclosed in an 8-inch PVC cylinder driven into the ground ≅2 inches and covered with pieces of window screen. Insecticide treatments were applied to whole plots on 17 May, 30 Jun, 12 Aug, and 28 Aug. Granular insecticides were preweighed, mixed with dry sand, and applied by gloved hand to the whole plot. Spray applications were made using a CO₂ sprayer equipped with 4 Spraying System 8004 Tee-Jet nozzles that deliver 2109 g pressure per cm². Conditions during application were 74,83,90, and 90°F respectively, with winds 5 mph or less. First post-treatment rainfall was on 18 May, 2 Jul, 24 Aug and 13 Sep when 0.09, 0.27, 0.52 and 0.12 inches fell for each application respectively. Plots were watered periodically to maintain the turf before and after applications due to severe drought. Plots were sampled on 23 Sep by cutting a 1.5 x 2 ft strip, about 3 inches deep with a motorized sod cutter. Sod strips were rolled back and examined for grubs. All grubs were collected and taken back to the lab for identification. At the time of sampling, total grub densities in untreated check plots averaged 13.5 per sample (4.5 per ft²). All treatments gave ≥ 72% reduction in total grub numbers. All treatments significantly reduced JB and total grub densities below untreated checks. There were no treatment effects on MC due to low numbers of grubs per sample. No phytotoxicity resulted from any treatment." |
