| Abstract/Contents: | "Field experiments were conducted at Deer Trails Country Club in Commerce, GA during 2019 and 2020. Research was conducted on mature infestations of dallisgrass present within a bermudagrass (Cynodon spp.) fairway. Plots (1.5 x 1.5 m) were arranged in a randomized complete block (RCB) design with 4 replications. Herbicides were applied with a CO2 powered backpack sprayer calibrated to deliver either 407, 814, or 1,628 L ha-1 at 221 kPa. Herbicide treatments were initiated on October 10, 2019 with sequential applications made on November 1, 2019. Treatments consisted of Monument (trifloxysulfuron) at 28, 56, and 112 g ai ha-1; Celero (imazosulfuron) at 0.42, 0.82, and 1.64 kg ai ha-1; Revolver (foramsulfuron) at 29, 58, and 116 g ai ha-1; and Tribute Total (thiencarbazone-methyl + foramsulfuron + halosulfuron-methyl) at 0.14, 0.27, and 0.54 kg ai ha-1 all applied at 407, 814, and 1,628 L ha-1, respectively. Revolver was applied with a non-ionic surfactant at 0.25% v/v while all other treatments were applied with a methylated seed oil at 0.5% v/v. An untreated check was added for comparison. Visual ratings of % cover were converted to % dallisgrass control. Long-term control (35 WAIT) was greatest in response to Monument at 112 g ai ha-1, Celero at 1.64 kg ai ha-1, and Tribute Total at 0.54 kg ai ha-1 sprayed at a volume of 1,628 L ha-1 (61, 54, and 53%, respectively). All other treatments that were sprayed at volumes of 407 and 814 L ha-1 resulted in dallisgrass control = 49%, regardless of herbicide 35 WAIT. Control with Revolver 35 WAIT was = 10%, regardless of rate or carrier volume. Use of higher rates of Monument, Celero, and Tribute Total in combination with higher spray volumes may improve dallisgrass control." |
