| Abstract/Contents: | "Experiments were conducted in 1989 to evaluate preemergence applications (Mid-March) of three formulations of prodiamine for crabgrass (mixed stand of smooth [Digitaria ischaemum (Schreb. ex Schweig.)Schreb. ex Muhl.] and southern [Digitaria ciliaris (Retz.)Koel.] control. Formulations were a 65% WD sprayable and a 0.5% clay (ABD) or gypsum (AGS) granule. In general, crabgrass control with these formulations was equivalent at 0.56, 0.84, or 1.12 kg ai/ha prodiamine. The AGS formulation at 560 kg/ha provided slightly less crabgrass control than the ABD or WD formulations, but this difference was usually not significant. Rates of 8.96, 1.0, and 0.7 kg/ha of pendimethalin, dithiopyr and prodiamine, respectively, were require to maintain 80% crabgrass control through mid-September. Following resumption of growth reduced canopy of common bermudagrass [Cynodon dactylon (L.)Pers.] was noted 1, but not 2, month after mid-March application of dithiopyr and prodiamine. Goosegrass [Eleusine indica (L.)Graetrn.] control in alow maintenance golf fairway (no fertilizer applied) was =<73% with 0.56, 0.84, or 1.12 kg/ha of the WD, ABD, or AGS formulations of prodiamine or 3.36 kg/ha pendimethalin 6 moths after treatment. No consistent pattern of goosegrass control was attributable to prodiamine formulation. At 6 months after treatment 0.84 kg/ha dithiopyr (granular formulation) had maintained >80% goosegrass control when visually estimated. When goosegrass control was calculated based on plant counts, 0.42 kg/ha dithiopyr provided >80% reduction of goosegrass plants. In the no-fertilizer situation, all rate => 0.42 kg/ha dithiopyr significantly reduced common bermudagrass density through the September (6 months after treatment) evaluation." |
