Roundup Weed & Grass Killer Concentrate, 32 oz

Root out the toughest weeds and grasses with Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate. This formula kills existing weeds and grass down to the root and prevents new weeds from growing for up to 4 months by creating an invisible barrier in the soil.

Apply only where you want to kill existing weeds and prevent future growth — cracks and crevices in driveways, sidewalks, and patios, along fences, in mulched beds, around the base of well-established plants, and on gravel areas. To prevent new weeds, spray the entire area you want to control, not just the emerged weeds. Rain or watering 30 minutes after application will not wash away effectiveness, and each 32 oz. container makes up to 4 gallons and covers up to 1,600 sq. ft.
