Sulfosulfuron showed the highest degree of nutsedge control after the first application among all of the treatments at 4 WAT. Nutsedge control began to decline at 6 WAT after a single application of sulfosulfuron. Halosulfuron, trifloxysulfuron, and penoxulam showed very good nutsedge control at 2 WAT after a second application was made. Trifloxysulfuron at 0.026 lb AI/A and penoxulam at 0.125 lb AI/A performed very similarly to halosulfuron at 0.047 and 0.062 lb AI/A. Halosulfuron and flazasulfuron were more effective at higher rates of application when a series of rates were compared. Halosulfuron at 0.047 and 0.062 lb AI/A were very similar at most rating dates and both rates gave acceptable nutsedge control of 86 to 88% control at the end of the season. The two highest rates of flazasulfuron at 0.023 and 0.047 lb AI/A gave almost acceptable control. Sulfentrazone was not effective in providing acceptable nutsedge control at the rate tested.
