Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate – 32 fl oz

Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate targets existing weeds and grasses while building a protective soil barrier to slow future growth. Designed for use on hardscapes and landscapes, it works in cracks and crevices in driveways, sidewalks, and patios, along fences, in mulched beds, or around the base of established desirable plants and trees, as well as on gravel areas. For best results, apply on warm, sunny days with temperatures above 60°F. Rain or watering within 30 minutes after application will not wash away effectiveness.

Visible results can begin quickly: treated weeds may yellow and wilt within hours, with complete kill typically in 1–2 weeks. The product covers up to 1,600 square feet when mixed at 6 fl oz per gallon and sprayed over the entire area you want to control. After application, ornamental bedding plants, trees, shrubs, sod, and seed can be planted again after a 4-month waiting period.

Usage guidance

Coverage and timing can help you plan outdoor maintenance with confidence: a single application covers up to 1,600 sq ft, giving you a broad-area option for driveways, sidewalks, patios, and landscaped borders. The 4-month preventer aspect provides a potential long-lasting barrier against new weed issues when applied correctly to the target area. Always follow product labeling for mixing and applying instructions to maximize effectiveness while respecting your outdoor spaces.
