| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%). Treatment plots were 9 X 6 ft, arranged in a RCB design, replicated 3 times. Liquid formulations were applied with a CO₂ compressed air sprayer with 4 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and delivering 5 gal/1000 ft². Granular formulations were applied with a hand held shaker and mixed with a fine grade top-dressing sand to facilitate product distribution. At treatment time (6 Aug), the following soil and environmental conditions existed: air temeprature, 59°F; soil temperature at 1 inch depth, 60°F; soil temperature at 2 inch depth, 58°F; RH, 75%; amount of thatch, 0.125-0.25 inches; soil type, loam; soil particle size analysis: 39.2% sand, 46.1% silt, 14.6% clay; soil moisture (oven baked) 33.5%; organic matter, 10.4%; water pH, 6-7; soil pH, 6.2; and clear skies. Immediately after treatment, each replicate was irrigated with 0.2 inches of water. Posttreatment counts were made 34 DAT (9 Sep). Three ft² sod samples were randomly taken from each replicate, and the total number of Japanese beetle grubs ft² was recorded. The experimental area was heavily infested with white grubs in the spring. Two treatments provided significant control. No phytotoxicity was noted." |
