| Abstract/Contents: | "The home lawn consisted primarily of perennial ryegrass (100%). Treatment plots were 9 X 6 ft, arranged in a RCB design and replicated 3 times. Granular formulations were applied with a hand-held shaker and mixed with a fine grade topdressing sand to facilitate product distribution. 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. At treatment time one (30 Aug), the following soil and environmental conditions existed: air temperature, 74°F; soil temperature at 1 inch depth, 76°F; soil temperature at 2 inch, 74°F; RH, 68%; amount of thatch, 0.125-.25 inches; soil type, silt-clay-loam; soil particle size analysis: 12.2% sand, 48.8% silt, 39.0% clay; organic matter, 4.5%; soil moisture (oven baked) 19.0%; water pH, 6-7; soil pH, 6.7; and partly cloudy skies. Immediately after treatment time one the experimental area was irrigated with 0.35 inches of water. At treatment time two (13 Sep) the following soil and environmental conditions existed: air temperature, 83°F; soil temperature at 1 inch depth, 84°F; soil temperature at 2 inch, 80°F; RH, 55%; amount of thatch, 0.125-0.25 inches; soil type, silt-clay-loam; soil particle size analysis: 12.2% sand, 48.8% silt, 39.0% clay; organic matter, 4.5%; soil moisture (oven baked), 14.6%; water pH, 6-7; soil pH 6.7; and partly cloudy skies. Immediately after treatment time two the experimental area was irrigated with 0.4 inches of water. Posttreatment counts were made 31 DAT (30 Sep). Three ft² sod samples were randomly taken from each replicate, and the total number of Japanese beetle grubs ft² was recorded. An average of 18.3 grubs/ft² were recorded at the time of treatment (30 Aug). All treatments provided significant control. No phytotoxicity was noted." |
