According to the Hi-Yield 2, 4-D Selective Weed Killer product label: For Spot treatment in non-crop areas: Use 1 pint in 3 gallons of water or 4 oz. in 3/4 gallon in a hand sprayer. In pastures and range land: Use 3 to 4 oz. in 1 to 3 gallons of water per 1,000 sq. ft. On Ornamental Turf: Use 16 oz. in 1 to 8 gallons of water per 2,725 sq. ft. or 2 gallons in 15 to 50 gallons per acre. Please review the product label for complete usage instructions.
