| Abstract/Contents: | "Winter weeds in dormant bermudagrass can have a significant effect on spring weed control programs, turf aesthesis, and bermudagrass green-up. Moreover, controlling winter weeds can be a problem in the southeastern US due to mild winters. Prodiamine, rimsulfuron, and isoxaben tank mixtures were measured for efficacy against annual bluegrass (Poa annua), common dandelion (Taraxacum officinale), common chickweed (Stellaria media), persian speedwell (Veronica persica), and parsley-piert (Alchemilla microcorpa). Two trials were initiated on October 28, 2010 in dormant bermudagrass in Blacksburg, VA. Prodiamine, rimsulfuron, and isoxaben were applied in varying tank mixtures at 1120g ai ha-1, 17.5g ai ha-1, and 840g ai ha-1, respectively. An additional simazine treatment at 1120 g ai ha-1 was also included as a comparison. All herbicide treatments were compared with a nontreated check. Weed cover and control were visually estimated. Weed counts were conducted with a 98 point grid on each plot. Bermudagrass green leaves were counted to assess the rate of postdormant bermudagrass growth ("greenup)" in spring. In March at 151 DAT, any mixture that contained rimsulfuron plus isoxaben or rimsulfuron plus prodiamine controlled all species 75 to 95% on Patriot bermudagrass and 83 to 99% on Riviera bermudagrass. Bermudagrass green leaf counts were negatively correlated to weed cover at both sites, suggesting treatments that controlled weeds increased bermudagrass spring greenup. Prodiamine alone and isoxaben alone both reduced cover of all weeds except common dandelion and annual bluegrass. Both common dandelion and annual bluegrass were already present when treatments were initiated. Rimsulfuron seemed to help control emerged weeds that prodiamine and isoxaben did not control, making the tank mixture more effective than either herbicide alone. These results suggest that the addition of rimsulfuron to prodiamine and isoxaben tank mixtures may increase winter weed control and contribute to faster bermudagrass green-up." |
