| Abstract/Contents: | "The turfgrass consisted primarily of annual bluegrass (50%) and creeping bentgrass (50%). 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 of top-dressing 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/1000ft2. At treatment time the following soil and environmental conditions existed: air temperature, 66 degrees F; soil temperature at 1 inch depth, 70 degrees F; soil temperature at 2 inch, 69 degrees F; RH, 85%; amount of thatch, 0.125 inches; soil type, loam; soil particle size analysis: 37.0% sand, 45.0% silt, 18.0% clay; organic matter, 5.0%; soil moisture (oven baked), 31.6; water, pH, 7.0; soil pH, 5.1; and overcast skies. Immediately after the treatment the experimental area was irrigated with 0.5 inches of water. Posttreatment counts were made 49 DAT (11 Oct). Japanese beetle grub control was evaluated by removing four 0.087 ft2 sod samples from each replicate, and the total number of grubs were recorded and converted to a ft2 count. Sod samples were removed with a 4 inch diam cup cutter. An average of 12.3 grubs/ft2 was recorded on 23 Aug. Four treatments provided significant control. No phytotoxicity was observed." |
