| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (50%) and creeping bentgrass (50%). Treatment plots were 9 x 6 ft, arranged in a randomized complete block design and replicated 3 times. Liquid formulations were applied by using 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/1000 ft². Granular treatments were applied with a fine grade top-dressing sand to facilitate product distribution. At treatment time (6 Jun), the following soil and environmental conditions existed: air temperature, 77°F; soil temperature at 1 inch depth, 80°F; soil temperature at 2 inch depth, 78°F; RH, 74%; amount of thatch, 0.25-0.5 inches; soil textural class, silt-loam; soil particle size analysis: 32.1% sand, 53.8% silt, 14.2% clay; soil moisture (oven dried), 31.1%; organic matter, 8.3%; water pH, 6.5; soil pH, 5.2; application time, late-morning; and cloudy skies. Immediately after treatment the experimental area was irrigated with 0.3 inch of water. Posttreatment counts were made on 6 Sep. The total number of new freshly constructed green June beetle burrows was recorded from each replicate (54 ft²) as well as the total number of green June beetle larvae flushed to the surface following an application of Sevin 80WSP over a 24 hr observation interval. One treatment significantly reduced burrow damage but no treatments significantly reduced the avg number of grubs flushed to the surface. No phytotoxicity was noted." |
