Abstract/Contents:"This experiment was conducted on a golf course fairway in Bedford County to assess the perofrmance of four formulations against a natural adult ABW population, while determining the effiacy of late applications of Mach 2 and Merit. The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%). Applications were made when flowering dogwood was in full bloom and adults were recorded from golf course greens. Treatment plots were 5 x 6 ft, arranged in a RCB design and replicated 3 times. Granular formulations were applied with a hand held shaker with top dressing sand added to provide optimum product distribution. At the first treatment time (10 May), the following soil and environmental conditions existed: air temp, 59°F; soil temp at 1 inch depth, 58°F; soil temp at 2 inch depth, 54°F; RH, 44%; amount of thatch, 0.0625-0.125 inch; water pH, 7; percent water content (percent by wt), 26.1%; application time, mid-morning; and clear sunny skies. Each replicate was irrigated immediately after treatment with 0.3 inch of water. At the second treatment time (26 May), the following soil and environmental conditions existed: air temp, 61°F; soil temp at 1 inch depth, 58°F; soil temp at 2 inch depth, 55°F; RH, 54%; amount of thatch, 0.0625-0.125 inch; water pH, 7; percent water content (percent by wt), 29.1%; application time, mid-morning; and clear sunny skies. Each replicate was irrigated immediately after treatment with 0.3 inch of water. General soil conditions observed at the experimental site were as follows: soil textural class, silt loam; soil particle analysis: 27.5% sand, 52.8% silt, 19.6% clay; percent organic matter, 7.3; and soil pH, 6.2. Post-treatment counts were made on 8 Jun. ABW control was evalutated by removing two 4-inch cup cutter sod samples from each replicate and recording the total no. of ABW life stages (larva, pupa) per sample. Totals were then converted to a ft² count. ABW adults were actively observed on golf course fairways, greens, and roughs before treatment. No treatments provided significant control and ABW populations collapsd in select untreated checks on 8 Jun. No phytotoxicity was noted."
