Abstract/Contents: | "The turfgrass area, located in Carbon County, PA, consisted primarily of Kentucky bluegrass (40%), annual bluegrass (40%), and perennial ryegrass (20%). Treatment plots were 8 x 6 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied by using a CO₂ sprayer with a 4 8004VS TeeJet nozzles mounted on a 6-ft boom, operating at 28 psi, and applied in 500 ml of water/48 ft² or delivering 2.7 gal/1000 ft². Granular formulations were applied with a hand-held shaker and mixed with fine top-dressing sand to facilitiate product distribution. At treatment time (19 Aug), the following soil and environmental conditions existed: air temperature, 70°F; soil temperature at 1-inch depth, 69°F; soil temperature at 2 inch, 69°F; RH, 68%; amount of thatch, 0.5-0.625 inch; soil textural class, silt loam to loam; soil particle size analysis; sand, 39.4%; silt, 50.5%; clay, 10.1%; organic matter, 20.9%; soil percent water content (pecent by weight), 36.3; water pH, 7.0; soil pH, 6.8; application time, mid-morning; and skies cloudy. Immediately after treatment select treatments were irrigated in with 0.2 inch of water. Post-treatment counts were made on 7 Oct. Three ft² sod samples were randomly taken from each replicate, and the total number of Japanese beetle grubs/ft² was recorded. Japanese beetle grubs sampled on 7 Oct were primarily third instars. White grub populations were depressed as a result of extremely dry summer weather conditions. All treatments provided significant control. No phytotoxicity was noted." |
