| Abstract/Contents: | "Dallisgrass (Paspalum dilatatum ) is a perennial grass weed common in most turf situations. Dallisgrass is a clumping perennial that produces unsightly seedheads in the summer and disrupts the uniformity of the turf. The purpose of this research was to investigate the efficacy of various postemergence herbicides for dallisgrass control. In the summer of 2002 two studies were conducted at Clemson University investigating postemergence dallisgrass control. Plot size for each treatment measured 2.0 m by 2.0 m, replicated three times. Treatments were applied with a CO2 backpack sprayer calibrated at 20 GPA, at 30 p.s.i., using 8003 flat fan spray tips. Treatments for study one included: Flazasulfuron (25 DG) at 0.05 lb ai/A (0 fb 21 DAI); Flazasulfuron + MSMA (6.6 SC) at 0.05 lb ai/A + 2.0 lb ai/A (0 fb 21 DAI); MSMA at 2.0 lb ai/A (0 fb 7 fb 21 DAI); MSMA + Sencor (75 DF) at 2.0 lb ai/A + 0.25 lb ai/A (0 fb 7 fb 21 DAI); Revolver (35 WG) (AEF 130360) at 0.03 lb ai/A (0 fb 21 DAI); Revolver + MSMA at 0.03 lb ai/A + 2.0 lb ai/A (0 fb 21 DAI). Initial applications for study one were made on July 5, 2002. Treatments for study two included: MSMA at 2.0 lb ai/A (0 fb 7 DAI); MSMA + Sencor at 2.0 lb ai/A + 0.25 lb ai/A (0 fb 7 DAI); Turflon Ester (4.0 EC) at 1.0 lb ai/A (0 fb 14 DA I); Turflon Ester + MSMA at 1.0 lb ai/A + 2.0 lb ai/A (0 fb 14 DAI); Tuflon Es ter + MSMA + Sencor at 1.0 lb ai/A + 2.0 lb ai/A + 0.25 lb ai/A (0 fb 14 DAI). Initial applications for study two were made on August 21, 2002. All treatments received a non-ionic surfactant (Lesco) at 0.25 % V/V. Visual dallisgrass ratings for study one were taken 4 DAT, 26 DAT, and 56 DAT. Visual ratings for study two were taken 7 DAT, 14 DAT, 22 DAT , and 55 DAT. Ratings for 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. On the final visual rating date of study one, 56 DAT, excellent (>90%) dallisgrass control resulted from all treatments containing MSMA at 2.0 lbs ai/A. Bermudagrass injury was not acceptable with any treatment containing MSMA 26 DAT, but had recovered by 56 DAT. Flazasulfuron and Revolver did not provide acceptable dallisgrass control. In study two, excellent dallisgrass control, 55 DAT, resulted from all treatments containing MSMA, except for MSMA + Sencor, which provided 85% control. Turflon Ester alone provided 75% dallisgrass control 55 DAT." |
