| Abstract/Contents: | "A field experiment was conducted during 1995 and 1996 in Georgia to determine the influence of Dimension (dithiopyr) and MSMA applied as sequential and tank-mixed treatments on large crabgrass [Digitaria sanguinalis (L.) Scop.] control in common bermudagrass [Cynodon dactylon (L.) Pers.]. Large crabgrass control by late August was equal to or higher when Dimension and MSMA were applied in a single tank-mixed application after weeds emerged in early May than when Dimension was applied as preemergence late February followed by MSMA as postemergence early June. Full season control ranged from ≥73% for tank-mixes of Dimension plus MSMA at 0.14 + 1.1 kg/ha (0.12 + 1.0 lb/A) to ≥93% when applied at 0.28 + 2.2 kg/ha (0.25 + 2.0 lb/A). The injury to common bermudagrass was due to MSMA and not related to Dimension. MSMA applied in May caused only slight discoloration but injury in June ranged from ≤42% in 1995 and ≤25% in 1996. The higher injury in 1995 was related to higher air temperature following treatments. When injury was observed, recovery occurred within 2 to 3 weeks." |
