Abstract/Contents: | "Research was conducted at the University of Florida West Florida Research and Education Center during 2001 and 2002 to evaluate flazasulfuron, a sulfonylurea herbicide, for tolerance in turfgrass. Eight turfgrass species common in the Southern U.S. were selected for study (Sea Isle 1 and Sea Isle 2000 Seashore Paspalum; Tifeagle, Tifdwarf, and Floradwarf bermudagrass; Common centipedegrass; Raleigh St. Augustinegrass; and Emerald Zoysiagrass). Four rates of herbicide (0.023 lbs a.i./A, 0.035 lbs a.i./A, 0.047 lbs a.i./A, 0.093 lbs a.i./A) were applied to the various species of turfgrass. All applications included a non-ionic surfactant at 0.25% v/v. Sea Isle 1 seashore paspalum showed significant injury early, but recovered quickly indicating moderate tolerance to flazasulfuron. Sea Isle 2000 seashore paspalum showed no injury at the .023 lbs a.i./A level, and showed little injury at other rates suggesting good tolerance. Tifeagle and Tifdwarf bermudagrass had significant damage early, but recovered well over time. Both varieties had moderate to good tolerance. The Floradwarf bermudagrass showed little injury early, but had significant damage over time indicating moderate to low tolerance. Common centipedegrass showed significant injury early with little recovery over time. Raleigh St. Augustinegrass showed little injury early, but had severe damage over time and appears to not tolerate flazasulfuron. Emerald zoysiagrass showed little injury throughout the study and had good tolerance to this herbicide." |
