Pasture Weed Control Database
Glyphosate must be applied in January or February while the Rattail Fescue is small to achieve effective control in dormant bermudagrass. A good rule of thumb is waiting for the high to reach 50 degrees three days in a row. Glyphosate works very slowly in cold weather. Use1.5 quarts per acre of 41% active ingredient glyphosate. Another important factor in control is adequate spray coverage. Our research herbicides are applied with a boom sprayer at 15 gal/A using 8002 flat fan nozzles on 20-inch spacing.
