For typical winter broadleaf weeds that are not affected by freezing temperatures, Cool Power Selective Herbicide is applied based on the area being treated rather than the sprayer size. The labeled turf rate is approximately 0.91 to 1.29 fluid ounces per 1,000 square feet, mixed in enough water to provide even coverage. Most 2-gallon hand pump sprayers apply about 2,000 square feet, so you would typically mix about 2.0 to 2.6 fluid ounces of product in 2 gallons of water. If you are treating tougher winter weeds or spraying fully dormant warm-season turf, using the higher end of the range is appropriate. Apply when temperatures are above roughly 50-65 °F and weeds are actively growing, as coverage and plant activity are key to good results.
