| 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 6ft) were blocked by irrigation treatment with four replicates. Natural infestations were augmented by inoculating each plot with ≅ 150 field-collected, adult JB on 13 Jul then again on 28 Jul. Beetles were enclosed in a 8-inch PVC cylinder driven into the ground approximately 2 inches and covered with pieces of window screen. Insecticide treatments were applied on 17 Jun. Granular treatments were pre-weighed, mixed with dry sand and applied by gloved hand. Liquid applications were applied using a CO₂ sprayer equipped with four Spraying System 8004 Tee-Jet nozzles that deliver 2109 g pressure per cm². Conditions during treatment were 82 °F with winds at 5 mph. Five post-treatment irrigation levels were used: 0-1 h, 6-9 h, 24 h, 72 h, and no irrigation. After the insecticide applications, all plots except the 0-1 h post-treatment irrigation and control plots were covered with a plastic tarp then the whole site received 0.5 inch or irrigation. The tarp was removed from the plots immediately after irrigation. Subsequent irrigation treatments were applied at 6, 24, and 72 h later in the same manner as the earlier treatment. The first post-treatment rainfall was 0.24 inch on 19 Jun. Plots were sampled on 10 Sep by cutting a 2 x 1.5 ft strip, about 3 inches deep, from each plot using a motorized sod cutter. Sample strips were taken adjacent to the center to avoid the inoculation area. 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 the untreated checks averaged 38.0 per sample (12.7 per ft²). All treatments significantly reduced grub densities below untreated checks. There was no evidence of phytotoxicity from any treatment." |
