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 bottom of the soil cores were even with the bottom of the pipe. A piece of fiberglass window screen was placed over each hole 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 6 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 6 replicas. Insecticide treatments were applied 9 Sep. Granular insecticides were mixed with dry sand and handshaken into the cylinders. The liquid formulations were sprayed with 10 ml water into the cylinders. The plot was then irrigated with 0.75 inches water. On 23 Sep, the cylinders were removed from the plot, the soil cores were broken apart, and the surviving SMC brubs were counted. All treatments provided significant control; Triumph and Oftanol gave >90% reduction relative to the untreated check. There was no apparent phytotoxicity from any treatment."
