Abstract/Contents:Fifteen commercially available and experimental herbicides were evaluated for preemergent control of smooth crabgrass at Spindletop Farm, Kentucky in 1987. An established Kentucky bluegrass turf was seeded with crabgrass in October 1986 and in early April 1987. Vertical mowing exposed some surface soil. Initial treatments were applied on April 20. Treatments with repeat applications were re-sprayed June 24. Replications (3) of treatments (40) were applied on 6x10 ft. plots. The turf was maintained at 1.5 inch height. Irrigation as needed prevented dormancy. Crabgrass was first observed on June 8. Percent crabgrass control is presented on 3 dates (June 16, July 10, Aug. 25) as are herbicidal effects on Kentucky bluegrass color (1-9 scale) and percent control of spurge, dallis, and foxtail. Three experimental herbicides on fertilizer are included in the study. MON 15126 3el at 1.5 lb ai/A was rated highest having 100% control on all three evaluation dates. Dallisgrass populations tend to increase with the control of smooth crabgrass.
