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 weed growth for up to 4 months, such as cracks and crevices in driveways, sidewalks, and patios, along fences, in mulched beds or around the base of well-established desirable plants, shrubs, or trees, and on gravel areas. In order to prevent new weeds and grasses from growing, you must spray the entire area you want to control, not just the emerged weeds. For best results, apply during warm, sunny weather above 60°F. Rain or watering 30 minutes after application will NOT wash away effectiveness. After application, weeds will begin to yellow and wilt within hours with complete kill in 1 to 2 weeks. All ornamental bedding plants (annuals and perennials), trees, shrubs, sod and seed can be planted 4 months after application. Roundup® Dual Action covers up to 300 sq. ft. ## Features - Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer with Sure Shot Wand kills existing weeds and grass down to the root and prevents new weeds from growing for up to 4 months - This weed killer and preventer is rainproof in as fast as 30 minutes, and produces visible results in as fast as 6 hours - Apply this herbicide to hardscapes and landscapes - cracks and crevices in driveways, sidewalks, and patios, along fences, in mulched beds or around the base of well-established desirable plants, shrubs, or trees, and on gravel areas - All ornamental bedding plants, trees, shrubs, sod, and seed can be planted 4 months after application - The innovative protective shield of the Sure Shot Wand allows you to use Roundup Dual Action with confidence to target weeds in garden beds and landscaped areas ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BDSV2LHC | | Active Ingredients | Fluazifop-P-butyl, Triclopyr, Triethylamine Salt | | Best Sellers Rank | #29,301 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #235 in Weed Killers | | Brand Name | Roundup | | Coverage | 300 square feet | | Customer Reviews | 4.6 4.6 out of 5 stars (1,764) | | Global Trade Identification Number | 10070183000613 | | Included Components | Weed & Grass Killer | | Item Form | Spray | | Item Type Name | Miracle-Gro - 5378304 | | Item Weight | 0.5 Pounds | | Liquid Volume | 1 Gallons | | Manufacturer | Scotts MiracleGro | | Model Number | Miracle-Gro - 5378304 | | Part Number | 5378304 | | UPC | 070183537839 | | Unit Count | 128.0 Fluid Ounces | | Warranty Description | Warranty | ## Product Details - **Active Ingredients:** Fluazifop-P-butyl, Triclopyr, Triethylamine Salt - **Brand:** Roundup - **Item Form:** Spray - **Item Weight:** 0.5 Pounds - **Liquid Volume:** 1 Gallons ## Images ![Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer - Image 1](https://m.media-amazon.com/images/I/71GYNTeFgcL.jpg) ![Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer - Image 2](https://m.media-amazon.com/images/I/81phUnxpaaL.jpg) ![Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer - Image 3](https://m.media-amazon.com/images/I/71v1a8Gz5+L.jpg) ![Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer - Image 4](https://m.media-amazon.com/images/I/71KQDuiPCaL.jpg) ![Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer - Image 5](https://m.media-amazon.com/images/I/71dUdcDHZVL.jpg) ## Frequently Bought Together - Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer with Sure Shot Wand, 1 gal. - Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer Refill, Kills & Prevents for up to 1 Year, 1.25 gal. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/483503984-roundup-dual-action-weed-and-grass-killer-plus-4-month](https://www.desertcart.sg/products/483503984-roundup-dual-action-weed-and-grass-killer-plus-4-month) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-28*
