| Abstract/Contents: | "False-green kyllinga (Kyllinga gracillima, FGK) infestations appear to be expanding in the mid-Atlantic states. In cool-season turfgrass, the most common herbicides available for weedy sedge control are sulfentrazone and halosulfuron. Both of these herbicides have been reported to control FGK inconsistently. Imazosulfuron is a new herbicide recently marketed for sedge control in cool-season turfgrass. More information is needed to develop strategies to deal with the rising incidence of FGK in cool-season turf. Studies were conducted at the Pete Dye River Course of Virginia Tech on a mixed tall fescue/KY bluegrass rough infested with 60 to 90 percent FGK. Treatments were initially applied on June 17, 2015 and repeat treatments, where applicable, were applied 6 weeks later. Herbicides were delivered in 280 L/ha spray solution using 11004 Turbo Teejet Induction nozzles to uniformly spray 1m X 2m plots. Halosulfuron (Sedgehammer Herbicide) was applied once or twice at 70 g/ha, sulfentrazone (Dismiss Turf Herbicide) was applied once at 280 g/ha, sulfentrazone + quinclorac + 2,4-D + dicamba (Q4 Plus Herbicide) was applied once at 1500 g/ha, imazosulfuron (Celero Herbicide) + MCPA + fluroxypyr + dicamba (Change Up Herbicide) was applied once at 420 and 2000 g/ha, respectively, and imazosulfuron (Celero Herbicide) + fenoxaprop + fluroxypyr + dicamba (Last Call Herbicide) was applied once at 420 and 368 g/ha, respectively. Nonionic surfactant (Induce) was mixed at 0.25 percent v/v with all halosulfuron- and imazosulfuron-containing treatments. Sulfentrazone controlled FGK 80 to 81 percent between 5 and 10 days after initial treatment (DAIT) but FGK recovered and was controlled only 53 percent and 28 percent at 21 and 40 DAIT, respectively. Unlike sulfentrazone, which exhibited maximum FGK control at 10 DAIT, halosulfuron and imazosulfuron exhibited peak FGK control at 21 and 63 DAIT, respectively. Halosulfuron controlled FGK 83 percent at 21 DAIT but not more than 31 percent at 63 DAIT and beyond. When applied twice at a 6-week interval, halosulfuron controlled FGK 99 percent at 63 DAIT and 80 percent at 91 DAIT. Imazosulfuron + fenoxaprop + fluoxypyr + dicamba controlled FGK 94 and 93 percent at 63 and 91 DAIT, respectively. The other 157 imazosulfuron-containing treatment controlled FGK 94 percent at 63 DAIT and 77 percent at 91 DAIT. These data suggest that imazosulfuron could be an important new product for FGK control and that sulfentrazone and halosulfuron will likely require repeat treatments for effective full-season control." |
