Abstract/Contents: | "The turfgrass area consisted primarily of annual bluegrass (40%), Kentucky bluegrass (40%), and perennial ryegrass (20%). Treatment plots were 9 x 6 ft, arranged in a RCB design, replicated 3 times. Liquid fomulations were applied with a CO₂ compressed air sprayer with four 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 water/1,000 ft². Granular treatments were applied with a fine grade top-dressing sand to facilitate product distribution. At treatment time (10 Jul) the following soil and environmental conditions existed: air temperature, 83°F; soil temperature at 1 inch depth, 88°F; soil temperature at 2 inch, 80°F; RH, 60%; amount of thatch, 0.375-0.5 inches; soil textural class, sandy loam; soil particle size analysis: 67.0% sand, 28.6% silt, 4.5% clay; organic matter, 22.0%; soil moisture (oven dry weight), 67.1; water pH, 7; soil pH, 6.4; application time, mid-afternoon; and overcast skies. Immediately after treatment the experimental area was irrigated with 0.175 inch of water and 0.1 inch irrigation 14 hr after treatment. Posttreatment counts were completed on 2 Oct. Three ft² sod samples were taken from each replicate, and the total number of viable Japanese beetle grubs/ft² was recorded. An average of 18.4 grubs/ft² was recorded on 22 Aug prior to the 1995 mid-summer application. Eight treatments provided significant control. No phytotoxicity was noted." |
