Abstract/Contents: | "Dallisgrass (Paspalum dilatatum) is a common perennial grass weed in turf. Dallisgrass is a clumping perennial that produces unsightly seedheads in summer and disrupts turf uniformity. The purpose of this research was to investigate potential postemergence dallisgrass control options with and without MSMA. In the fall of 2006 and 2007, studies were conduced at Clemson University investigating dallisgrass control with various postemergence herbicides. Plot size for the each treatment measure 2.0 m by 3.0 m, replicated three times. Treatments were applied using a CO2 backpack sprayer calibrated at 20 GPA, at 31 p.s.i., with 8003 flat fan spray tips. Initial treatments for Study 1 were applied on September 4, 2006 while, initial treatments for Study 2 were applied on September 20, 2007. Treatments for Study 1 included: MSMA (6.6L) at 1.5 lb ai/A (Int.) fb Revolver (0.19SC) at 0.06 lb ai/A (7 & 30 DAI); MSMA at 1.5 lb ai/A (Int.) fb Revolver + 21-0-0 at 0.06 lb ai/A + 0.85 lb ai/A (7 & 30 DAI); MSMA at 1.5 lb ai/A (Int.) fb Revolver + MSO at 0.06 lb ai/A + 1.0 % V/V (7 & 30 DAI); MSMA at 1.5 lb ai/A (Int.) fb Revolver + 21-0-0 + MSO at 0.06 lb ai/A + 0.85 lb ai/A + 1.0 %V/V (7 & 30 DAI). Treatments for Study 2 included: Revolver at 0.06 lb ai/A (Int. & 30 DAI); Revolver + Sencor (75DF) at 0.06 lb ai/A + 0.5 lb ai/A (Int. & 30 DAI); Dismiss (4L) at 0.25 lb ai/A (Int. & 30 DAI); Dismiss + Sencor at 0.25 lb ai/A + 0.5 lb ai/A (Int. & 30DAI); Certainty (75DF) at 0.06 lb ai/A (Int. & 30 DAI); Certainty + Sencor at 0.06 lb ai/A + 0.5 lb ai/A (Int. & 30 DAI). Visual control ratings were taken throughout the study. Ratings for dallisgrass control were based on a scale of 0 - 100% with 0% representing no control and 100% representing complete control. Common Bermudagrass turf injury was evaluated on a 0 - 100% scale with 0 % representing no turf injury and 100% representing dead turf Dallisgrass control for Study 1 on September 25, 2007 (386 Days after initial treatment, DAIT) all treatments containing MSMA at 1.5 lb ai/A followed by a Revolver application at 0.06 lb ai/A, 7 and 30 days after the initial treatment were providing greater than 95 percent control. With Study 2 treatments containing Revolver at 0.06 lb ai/A applied twice 30 days apart provided greater than 70 percent control on October 30, 2007 (40 DAIT). Study 2 will continue to be evaluated in 2008 for long-term residual dallisgrass control. Future Research at Clemson University will be to investigate new and existing herbicides for dallisgrass control, which include adjusting rates and timings of treatments. Repeat current studies and evaluate the long-term residual control of these treatments for dallisgrass control." |
