| Abstract/Contents: | "On 17 Aug, 9 insecticides were applied to 4 X 6 ft Kentucky bluegrass plots located in a golf course rough at Lincoln, Nebraska. Topography in the treated area ranged from level to a gentle slope, and the predominant grass species was Kentucky bluegrass (95%). Thatch accumulation (finger compressed) ranged from 0.25 to 0.5 inches. Field conditions at the time of application were as follows: air temperature, 74oF; soil temperature (4-inch depth), 74oF; soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6.7; water pH, 7.0; soil moisture was well below field capacity. Granular formulations were applied with a precalibrated Gandy 24H12 spreader. Liquid formulations were applied with a C02 sprayer using a LF-4 nozzle at 24 psi and a 3 gal/1000 ft2 spray rate. The experiment was replicated 4 times using a randomized complete block design. Immediately following insecticide applications, the test area was irrigated with approximately 0.50 inch of water. An additional 0.4 inch of irrigated water was applied, and 13.3 inches of rain fell during the post-treatment period. Product efficacy was evaluated 28 DAT (14 Sep) by removing two 1 ft2 sections of sod, ca 2 inches deep, from each plot and counting the number of suviving grubs. All treatments resulted in statistically significant reductions in white grub numbers. All products except Dylox 80 SP provided greater than 85% reduction. No phytotoxicity was observed." |
