Bonide KleenUP he Concentrate is a highly efficient, fast-acting, nonselective herbicide designed to kill over 200 types of weeds, brush, and grasses in one application. Starts working upon contact and kills down to the root so weeds won't grow back. This product is rainfast in just hours after application so it won’t be washed away. Treated areas can be reseeded four days after application. Best used outdoors especially around trees, gardens, sidewalks, and driveways. Use 3-8 oz. per gallon of water depending on your target weeds. One gallon of mixed solution treats 1000 sq. ft. See label for complete application instructions.
