Abstract/Contents:"The turfgrass, located in University Park, PA, consisted primarily of perennial ryegrass (100%). 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 4 8002VS TeeJet nozzles mounted on a 6-ft boom, operating at 28 psi, and applied in 727 ml of water/48 ft² or delivering 4 gal/1000 ft². Granular formulations were applied with a hand-held shaker and mixed with fine top-dressing sand to facilitate product distribution. Three white PBC cylinders (8-inch diam x 6-inch height) were placed in each replicate and secured in place. Twenty-five JB adults were placed within each chamber and maintained inside by covering individual cylinders with white shade cloth. The latter procedure allowed for oviposition by adult females. PBC cylinders were removed following death of adult beetles. At treatment time (8 Aug) the following soil and environmental conditions existed: air temperature, 68°F; soil temperature at 1-inch depth, 64°F; soil temperature at 2 inch 63°F; RH, 72%; amount of thatch, 0.0625-0.125 inch; soil textural class silty clay loam; soil particle size analysis: 16.4% sand, 55.0% silt, 28.6% clay; organic matter, 6.7%; soil percent water content (percent by weight), 22.3; water pH, 7.0; soil pH, 6.9; treatments were applied in mid-morning; and clear skies. The experimental area was irrigated with 0.1 inch of water after treatments had dried. The area received extensive pre-irrigation watering because of the extremely dry weather conditions with 4.5 inches applied from Jul 2 through Jul 17. Additional irrigation was applied on an as needed basis. Posttreatment counts were completed on 25 Sep. Three ft² sod samples were randomly taken from each replicate, and the total number of JB grubs/ft² was recorded. An average of 6.3 grubs/ft² was recorded on 25 Sep. Grubs sampled on 25 Sep were primarily 3rd instar. All treatments provided significant control. No phytotoxicity was recorded."
