| Abstract/Contents: | "Three field studies were conducted during 1987, 1988, 1989 to evaluate the effectiveness of a spray adjuvant, Frigate, when used with reduced rates of glyphosate for the selective control of johnsongrass on common bermudagrass roadsides. Glyphosate, was applied at rates of 0.25, 0.38, 0.5, and 0.75 lb.ai./A, alone, and in combination with frigate at 0.5% v/v and/or sulfometuron at 0.094 lb.ai./A in each of the studies. Treatments were applied in late May or early June to actively growing bermudagrass and 12 to 24 inch tall johnsongrass. Treatments were applied to 5 ft. by 10 ft. plots using a CO(2) - powered, hand-held boom sprayer calibrated to deliver 40 gallons per acre. The level of johnsongrass control was significantly increased by the addition of Frigate to a particular treatment when compared with the same treatment without it during 1987 and 1989 for 1, 2, and 3 month-after-treatment (MAT) evaluations. Current use rates of glyphosate plus sulfometuron combinations for johnsongrass control in Oklahoma are 0.75 plus 0.094 lb.ai./A respectively. Data indicates the addition of Frigate at 0.5% v/v to reduced rates of glyphosate (0.5 lb.ai./A) in combination with sulfometuron, will consistently maintain acceptable johnsongrass control. The addition of Frigate to a particular herbicide treatment significantly increased bermudagrass phytotoxicity 1 MAT at the 1987 and 1989 studies. This was not evident during the 1988 study. The level of phytotoxicity from all treatments at 1 MAT would be acceptable for a roadside situation, except for the highest rate of glyphosate (0.75 lb.ai./A) with Frigate and sulfometuron. At 2 MAT only the highest rates of glyphosate with Frigate were producing minimal phytotoxic effects on bermudagrass." |
