| Abstract/Contents: | "This study was conducted in a Kentucky bluegrass plot in Fayette County, Ky. The established turf was on a Maury silt loam soil (fine-silty, mixed, mesic Typic Paleudalf) with pH 6.2 Thatch accumulation was < 0.25 inches. On 2 Sep. turf/soil cores (6 by 6 inches) were removed from the plot and set inside 6-inch-diam by 7-inch -long sections of plastic pipe; the bottoms of the soil cores were even with the bottom of the pipe. A piece of fiberglass window screen was placed over ends of pipe and the pipes and cores were replaced in the plot. The plot was then irrigated. Third-instar SMC grubs were collected from an untreated golf course rough on 5 Sep. Ten SMC were placed in each cylinder; those that did not burrow into the soil within 10 min were replaced. Treatments were arranged in a randomized complete block design with 5 replicates. Insecticede treatments were applied on 7 Sep. Granular insectidedes were mixed with dry sand and hand shaken into the cylinders. The liquid formulations were sprayed with 10 ml of water into the cylinders. The plot was then irrigated with 0.75 inches water. On 21 Sep, the cylinders were removed from the plot, the soil cores were broken apart, and surviving SMC grubs were counted. All treatments except RH 6808, RH 5849, and RH 1266 at the low rates, provided significant control. XRM-4902, Triumph, Sevinmol, and Sevin gave > 90% reduction relative to the untreated check. There was no apparent phytotoxicity from any treatment." |
