| Abstract/Contents: | "An experiment was conducted during 1988 to evaluate several herbicides and herbicide combinations for their efficacy on smooth crabgrass (Digitaria ischaemum) (Schreb.) Michx. in a mixed stand of cool season turfgrasses. Control ratings of 85 percent or higher were considered to be commercially acceptable. Of the commercially available materials, the wettable and granular formulations of DCPA provided acceptable control, but the flowable formulation did not (80%). The granular formulation of oxadiazon provided acceptable control at 2.24 kg ai/ha, but comparable rates of the ME formulation did not. The wettable formulation of oxadiazon only provided acceptable control at the highest rate (2.24 kg ai/ha). Pendimethalin, formulated on fertilizer and as a water dispersed granule, provided excellent control, although control was somewhat better when sprayed. Granular benefin provided acceptable control at the recommended rate. An experimental dry flowable formulation also provided acceptable control, but the rate tested was 2.69 kg ai/ha (equivalent to a 1.2X rate). Excellent control was obtained from the benefin-trifluralin provided very good control. Of the experimental materials tested, prodiamine provided excellent control at both rates used. CGA-41065 at the low rate did not provide acceptable control, but at the high rate control was excellent (94%). Cinmethylin did not provide acceptable control at either rate tested. Both formulations of the MON experimental product provided excellent control at the higher rates tested. The granular formulation appeared to be more active at lower rates than when the compound was sprayed." |
