Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate, 32 fl. oz. Simplified title: Roundup Dual Action Weed & Grass Killer Concentrate, 32 fl. oz.

Roundup® Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate is a powerful solution designed to tackle the toughest weeds and grasses. This formula kills existing weeds and grass down to the root, while also preventing new weeds from growing for up to 4 months by creating an invisible barrier in the soil.

To use this product effectively, apply it only to the areas where you want to kill existing weeds and prevent future weed growth for up to 4 months. These areas can include 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. It's important to spray the entire area you want to control, not just the emerged weeds, in order to prevent new weeds and grasses from growing.

For best results, apply Roundup® Dual Action Concentrate during warm, sunny weather when temperatures are above 60°F. The product is rainproof in as fast as 30 minutes, and you'll see visible results within as little as 6 hours. Rain or watering 30 minutes after application will not wash away the product's effectiveness.

After application, weeds will begin to yellow and wilt within hours, with complete kill in 1 to 2 weeks. This means you can enjoy a weed-free landscape for up to 4 months. During this time, all ornamental bedding plants (annuals and perennials), trees, shrubs, sod, and seed can be planted without any issues.

To apply, simply add 6 fl. oz. of Roundup Dual Action Concentrate per gallon of water into a tank sprayer, mix thoroughly, and spray the desired areas. This concentrated formula covers up to 1,600 sq. ft., making it a cost-effective solution for your weed control needs.

In summary, Roundup® Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate is a powerful and versatile product that can help you effectively tackle existing weeds and prevent new ones from growing for up to 4 months. Its rain-resistant formula and fast-acting results make it a reliable choice for maintaining a healthy, weed-free landscape.
