| Abstract/Contents: | "The turfgrass area consisted primarily of annual bluegrass (20%), Kentucky bluegrass (40%), and perennial ryegrass (40%). 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 applied in 1021 ml of water/54 ft² or delivering 5 gal/1,000 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 (25 Aug) the following soil and environmental conditions existed: air temperature, 81°F; soil temperature at 1 inch depth, 74°F; soil temperature at 2 inch, 72°F; RH, 76%; amount of thatch, 0.125-0.25 inches; soil textural class, loam; soil particle size analysis: 43.6% sand, 36.4% silt, 20.0% clay; organic matter, 7.6%; soil moisture (oven baked), 31.3; water pH, 6-7; soil pH, 6.6; and clear skies. Immediately after treatment the experimental area was irrigated with 0.2 inches of water. Three hours prior to treatment the area received 0.3 inches of natural rainfall. Posttreatment counts were completed on 28 Sep. Three ft² sod samples were taken from each replicate, and the total number of viable Japanese beetle grubs/ft² was recorded. An average of 12.1 grubs/ft² was recorded on 25 Aug prior to treatment. All treatments provided significant control. No phytotoxicity was noted." |
