| Abstract/Contents: | "Dallisgrass (Paspalum dilatatum) is one of the most difficult weeds to manage because it tolerates most selective herbicides. Standard herbicide treatments MSMA + Sencor and repeated applications of MSMA usually provide only moderate success. No single selective herbicide application has been able to control this troublesome perennial because of the enormous supply of carbohydrates in its short stubby rhizomes and extensive anchoring root system. Monument (trifloxysulfuron) is a new herbicide manufactured by Syngenta and released for use in bermudagrass and zoysiagrass for 2004. The herbicide provides excellent control of several sedge species, broadleaves, and grasses. Dallisgrass is listed as a suppressed species on the Monument label. A dallisgrass control experiment was conducted at Sugarland Country Club in Raceland, LA on a common bermudagrass fairway with a very heavy natural population of dallisgrass. The purpose of this experiment was to evaluate Monument applied in single and sequential applications, and tank-mixed with MSMA versus standard treatments for improved dallisgrass control. The study was initiated on May 26. Sequential MSMA applications occurred approximately 14 days after the initial application (DAI) and sequential Monument or Monument + MSMA was applied approximately 28 DAI. A third application of MSMA was applied to burn back dallisgrass regrowth approximately 20 days after 2nd application. Herbicide treatments were replicated 3 times in the fairway. Acceptable turfgrass injury was observed for all treatments of Monument, MSMA, or tank-mixes of the two herbicides. A single application of Monument at 0.50 oz/A or MSMA at 40 oz/A provided no greater than 33% dallisgrass control 80 days after initial treatment. A single application of Monument + MSMA tank-mix controlled approximately 30% of dallisgrass. However, three applications of MSMA or two applications of Monument + MSMA provided excellent control (95%) and were visually more effective than two sequential Monument applications (72%). A single application of Monument + MSMA controlled approximately 50% of dallisgrass. However, three applications of MSMA or two applications of Monument + MSMA provided excellent control (95%) and were visually more effective than two sequential Monument applications (77%) or two sequential applications of MSMA + Sencor (73%). Although two applications of Monument + MSMA provided excellent dallisgrass control, MSMA applied in three correctly timed applications provided an equivalent level of control and cost significantly less." |
