Abstract/Contents:Briefly summarizes the results of a study evaluating four herbicides for crabgrass control. Dimension (dithiopyr), Acclaim (fenoxaprop), Impact (quinclorac), and MSMA, alone and in tank mixes, were evaluated for control of 1-tiller smooth crabgrass. "Acclaim controlled crabgrass at 0.08 lab/A, reaching 85% control within 3 weeks. Dithiopyr required 0.38 lb/A for similar control. At higher rates (0.12 lb/A), Acclaim provided ≥ 95% control within 3 weeks, whereas dithiopyr required 4 to 6 weeks to provide similar control. Impact did not provide complete control and showed no rate response between 0.5 and 0.75 lb/A. A second applicaiton appears to be necessary to obtain control equal to that obtained with Acclaim. Two applications of MSMA at 1 lb/A applied 21 days apart, provided complete control of smooth crabgrass....Tank mixing Acclaim with pendimethalin or Dimension provided complete, season-long control. Tank mixes of Acclaim with Impact were antagonistic and provided less control than either product alone. Tank mixing MSMA with Dimension provided a more rapid 'knock-down' compared to Dimension alone and slightly improved levels of control at lower rates."
