| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (50%), Kentucky bluegrass (25%), and perennial ryegrass (25%). Treatment plots were 9 X 6 ft, arranged in a RCB design, replicated 4 times. Two ft untreated barriers were placed between each treatment replicate. Liquid formulations were applied with a hand held sprinkling can in 2.2 gal water. At treatment time one (26 Aug) the following soil and environmental conditions existed: air temperature, 76°F; soil temperature at 1 inch depth, 74°F; soil temperature at 2 inch, 72°F; RH, 72%; amount of thatch, 0.25-0.5 inches; soil type, clay-loam; soil particle size analysis: 22.1% sand, 47.5% silt, 30.3% clay; organic matter, 6.7%; soil moisture (oven baked), 23.5%; water pH, 6-7; soil pH, 6.0; and partly-cloudy skies. Immediately after treatment the experimental area was irrigated with 0.35 inches of water. At treatment time two (16 Sep) the following soil and environmental conditions existed: air temperature, 78°F; soil temperature at 1 inch depth, 74°F; soil temperature at 2 inch, 72°F; RH, 75%; amount of thatch, 0.25-0.5 inches; soil type, clay-loam; soil particle size analysis: 22.1% sand, 47.5% silt, 30.3% clay; organic matter, 6.7%; soil moisture (oven baked), 33.6%; water pH, 6-7; soil pH, 6.0; and partly-cloudy skies. Immediately after treatment two the experimental area was irrigated wtih 0.25 inches of water. Posttreatment counts were made 42 DAT (7 Oct). Three ft² sod samples were randomly taken from each replicate, and the total number of Japanese beetle grubs/ft² was recorded. An average of 7.6 grubs/ft² was recorded on 18 Aug. One treatment provided significant control. No phytotoxicity was noted." |
