Drexel Pin Dee 3.3 Herbicide is not labeled for use on watermelons. You may consider an alternative, such as Monterey Vegetable & Ornamental Weeder, which is labeled for use on watermelons, and is a pre-emergent herbicide that helps to control grasses and broadleaf weeds. The application rate is 3 oz. of product per 2 gal. of water per 1,000 sq. ft., spraying the solution directly onto the soil.
