| Abstract/Contents: | "Dallisgrass (Paspalum dilatatum) is a clumping perennial grass weed common in turf areas. Dallisgrass produces unsightly seedheads in the summer and disrupts the uniformity of the turf. The purpose of this research was to investigate summer versus fall application timings of Revolver (foramsulfuron) and MSMA for postemergence dallisgrass control in bermudagrass turf. In the summer and fall of 2004 and 2005, four studies were conducted by Clemson University on bermudagrass golf course rough in Sunset, SC, investigating postemergence dallisgrass control. Treatments were applied with a CO2 backpack sprayer calibrated at 40 GPA, at 31 PSI, using 8003 flat fan spray tips. Plot sizes measured 2.0 m by 3.0 m. Treatments were replicated three times. Treatments were identical for all four studies. Treatments included: Revolver (foramsulfuron, 0.19 SC) at 0.09 lb ai/A (0 fb 7 DAI); Revolver at 0.09 lb ai/A (0 fb 14 DAI); Revolver at 0.09 lb ai/A (0 fb 21 DAI); MSMA (6.0 SC) at 1.5 lb ai/A (0 fb 7 DAI); MSMA at 1.5 lb ai/A fb Revolver at 0.09 lb ai/A (7 + 28 DAI); Revolver + MSMA at 0.09 lb ai/A + 1.5 lb ai/A (0 fb 7 DAI) fb Revolver at 0.09 lb ai/A (28 DAI); and Revolver + MSMA at 0.09 lb ai/A + 1.5 lb ai/A (0 fb 7 DAI). Initial applications were made on July 6, 2004; September 21, 2004; July 19, 2005 and September 7, 2005. All treatments received non-ionic surfactant at 0.25% V/V. Visual ratings for summer 2004 applications were taken 7, 14, 21, 42, 63, 84, 105 and 126 DAI. Visual ratings for fall 2004 applications were taken 7, 28, 49 and 63 DAI. Visual ratings for summer 2005 applications were taken 14, 21, 28, 49, 56, 63, 70, 84 and 112 DAI. Visual ratings for fall 2005 applications were taken 7, 14, 21, 35 and 63 DAI. Ratings for dallisgrass control were based on a scale of 0-100%, with 0% representing no control and 100% representing complete control. Ratings for bermudagrass injury were based on a scale of 0-100%, with 0% representing no damage and 100% representing dead turf. MSMA applied initially, followed by Revolver at 7 and 28 DAI, provided continuous excellent (>90%) Dallisgrass control 21 - 84 DAI in summer and 35 - 63 DAI in fall. A previous study showed Revolver applied initially, followed by MSMA at 7 DAI, provided only minimal control early (45 % at 21 DAI) and very poor long-term control (8% at 49 DAI). All treatments including both Revolver and MSMA provided excellent (>90%) Dallisgrass control at 63 DAI in summer and fall. Bermudagrass injury was acceptable (< 30%) with all treatments, during the entire rating period, for all 4 studies. Future research will continue screening new and experimental herbicides, applied with and without MSMA, for dallisgrass activity. Research with herbicides in this study will continue to evaluate additional combinations and timings. Future research will examine staggered treatment timings with MSMA followed by various sulfonylurea herbicides." |
