Abstract The driving range consisted of annual bluegrass (60%) and crabgrass (40%). Treatment plots were 6 × 9 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied 20 Aug with a CO2 sprayer with four 8504 Tee Jet nozzles mounted on 6-ft boom, operating at 35 psi with a 4 gal/1,000 ft2 spray rate. Granular formulations were mixed with sand top-dressing to facilitate product distribution. Then they were applied with a hand held shaker. At treatment time, the following soil and environmental conditions existed: air temp, 85°F; soil temp at 1-inch depth, 73°F; soil type, silt loam; soil pH, 5.8; % organic matter, 3.9; soil condition, dry; % soil moisture, 13.4; amt thatch 0.25-1.0 inches; water pH, slightly acidic; % RH, 70; and clear sunny skies. A total of 2.7 inches of rain was recorded over the posttreatment period.
