| Abstract/Contents: | "A field study was conducted in 2003 to evaluate the efficacy of sulfosulfuron for controlling purple nutsedge (Cyperus rotundus) in a mixed stand of Tifway 419 bermudagrass (Cynodon dactylon x C. transvaalensis) and common bermudagrass (Cynodon dactylon). The experimental site was located at Pebble Creek Country Club, near College Station, Texas. The soil type was a Lufkin fine sandy loam containing less than 1% organic matter. All treatments were applied with a CO2 backpack sprayer calibrated to deliver 20 GPA. Treatments were replicated four times and arranged in a RCB design. Initial applications made on June 16, 2003, included sulfosulfuron at 0.66, 0.75, 1.0,1.33,1.5 and 2.0 oz./acre of herbicide product formulated as a 75% active WG. Manage (halosulfuron) was included as a standard, applied at 1.33 oz./acre. Sequential applications were made on August 27, 2003. These included sulfosulfuron applied at 0.66 and 1.33 oz./acre sequentially to the initial 0.66 and 1.33 oz./acre treatments, respectively. A sequential treatment of Manage was also applied at 1.33 oz./acre over an initial rate of 1.33 oz./acre. When evaluated 35 DAT, all treatments provided in excess of 95% purple nutsedge control. When evaluated 64 DAT, only the sulfosulfuron treatments equal to or above 1.33 oz./acre exceeded 88% control. At 104 DAT, only sulfosulfuron rates of 1.0 oz./acre and Manage at 1.33 oz./acre provided control ranging from 80-85%. When the sequential applications were evaluated 32 DAT, control ranged from 91-99 %. The mixed stand of turfgrass was adversely affected only by rates of sulfosulfuron equal to or greater than 1.33 oz./acre. Visual growth inhibition ranged from 18-25%, when evaluated 14 DAT. By 35 DAT, this inhibition decreased to less than 14 %. Both sequential applications of sulfosulfuron and the sequential Manage treatment caused growth inhibition ranging from 15-18%." |
