| Abstract/Contents: | "Two experiments were conducted to compare glyphosate formulations for winter and summer weed control. In the first experiment, treatments consisted of Roundup Pro, Roundup Pro Dry, Dupont Glyphosate, Glypro, Glypro Plus, or Touchdown Pro, which were applied at 0.5 or 1.0 lb ai/A on March 23, 2001. Dupont Glyphosate and Glypro were applied with and without the addition of Surf Aid, and 80/20 surfactant, at 0.25% v/v. Dupont Glyphosate or Glypro applied at 0.5 lb/A without additional surfactant provided 53 or 43% control of Italian Ryegrass (Lolium multiflorum Lam.), and when Surf aid was added at 0.25% v/v, control increased to 76 or 78% 54 DAT. All other treatments at the same rate provided 63 to 68% control of Italian ryegrass 54 DAT. Dupont Glyphosate or Glypro applied at 1.0 lb/A without additional surfactant provided 53 or 35% control of tall fescue (Festuca arundinacea Schreb.). When Surf Aid was added, control increased to 78 or 60%. Among all other treatments applied at 1.0 lb/A, control of tall fescue ranged from 75 to 80% 54 DAT. All treatments applied at 1.0 lb/A provided 78 to 88% control of Carolina geranium (Geranium carolinianum L.) 54 DAT. In the second experiment, treatments consisted of Roundup Pro, Roundup Pro Dry, Touchdown Pro, Dupont Glyphosate, Glypro, or MON 78754 which were applied at 0.33 or 0.66 lb ai/A on June 18, 2001. All herbicides in this experiment were applied with or without Timberland 90, a 90/10 surfactant, at 0.25% v/v. Glypro applied at 0.66 lb/A provided 73% control of johnsongrass (Sorghum halepense L.); When additional surfactant was added, control increased to 90% 33 DAT. All other treatments provided 80 to 90% control at the same rating interval. At 58 DAT, johnsongrass control ranged from 70 to 80% with all herbicides applied at 0.66 lb/A with additional surfactant. Slender aster (Aster exilis Ell.) was controlled 80 to 90% when glyphosate was applied at 0.66 lb/A with an additional surfactant." |
