APPLICATION RECOMMENDATIONS

Cool season grasses: Apply this product at the rate of 2.5 to 3.87 pints in 20 to 240 gallons of spray solution per acre (0.9 to 1.5 fluid ounces in 0.5 to 4 gallons of water per 1,000 square feet) to control (or kill) weeds growing in ornamental lawn turf planted to Kentucky bluegrass, perennial ryegrass, tall fescue or fine fescue. 

Warm season grasses: Apply this product at the rate of 2 to 3 pints in 20 to 240 gallons of spray solution per acre (0.7 to 1.1 fluid ounces in 0.5 to 4 gallons of water per 1,000 square feet) to control weeds growing in Bermudagrass or Zoysiagrass. Application to other grass species including Bahiagrass, Kikuyugrass, Centipedegrass, Carpetgrass, or St. Augustinegrass should be avoided unless injury can be tolerated. Avoid applications to warm season grasses emerging from winter dormancy unless a slight delay in spring green-up can be tolerated. 

Bentgrass Turf (Other than golf course greens and tees): On closely mowed Bentgrass, apply this product at a maximum rate of 2.5 pints per acre (0.9 fluid ounces in 3 gallons of water per 1,000 square feet) in May or mid-August through September when weeds are actively growing. Exercise care when applying to avoid overdosing Bentgrass, or turf injury may result. Slight turf yellowing should disappear after about one week. 

Bentgrass Turf (putting and bowling greens): On closely mowed Bentgrass, apply this product at a maximum rate of 1 fluid ounce in 5 gallons of water per 1,500 square feet, preferably in May or mid-August through September. Slight turf yellowing will disappear after about one week.
