| 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 (pH = 6.4) with negligible thatch. Plots (6 X 6 ft) were arranged in a RCB design with 4 replicates. The turf was treated on 29 Aug, when soil populations consisted of primarily 2nd instars, with some 3rd instars. Conditions during application were 84°F with winds < 10 mph. The whole site received ½ inch irrigation as soon as the last treatment was applied. There was no additional water on the site until 7 Sep, when it rained 0.82 inch. Granular formulations were preweighed, mixed with dry sand, and applied by gloved hand. Plots were sampled on 17 Sep by cutting a 3 X 1.5 foot strip, about 3 inches deep, from the center of each plot with a motorized sod cutter. Sod was rolled back, broken apart, and examined for grubs which were counted and identified. The data presented are based on three replicates because no grubs were present in one whole block. At time of sampling, densities in control plots averaged about 22 grubs per sample (4.9 per ft₂). Grub densities were low throughout Kentucky this year. All the treatments resulted in significantly lower grub densities than that in the untreated check. But, there were no significant differences between different treatments of halofenozide with one another and with the imidicloprid. There was no evidence of phytotoxicity in any treatment." |
