In zoysiagrass or tall fescue use Fusilade II (fluazifop) at 6 fluid ounces per acre plus Turflon Ester at 32 fluid ounces per acre to suppress bermudagrass. Begin around June 1 and repeat every four weeks unless the zoysiagrass has not recovered from the first application. In centipedegrass, Segment (sethoxydim) may be used at 24 fluid ounces per acre to suppress bermudagrass. Do not apply Segment sooner than three weeks after green-up and more than twice per season. Do not tank mix sethoxydim with other pesticides or fertilizers. Bermudagrass Preplant Control. Make three or four applications of 41% ai glyphosate or higher at 2 to 3 quarts per acre over the growing season (May, July and September). Wait for regrowth before making the next application. Using this method does not guarantee complete control. Tank mixing with 24 fluid ounces per acre of Fusilade II may improve control. Do not seed for 30 days after applying Fusilade II.
