Root out the toughest weeds and grasses with Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer with Pump 'N Go. 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.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

Q: Is this product safe for use around animals?

2 years ago
2 Answers
  • Roundup Consumer Services
    A: Hello! Thanks for your question. When used according to the label directions Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer poses no unreasonable health risks. Pets such as cats and dogs should stay out of treated areas until it is thoroughly dry. If you are unsure that the product is dry, wait 24 hours. This is to minimize exposure to the product. Once the area has dried, rain/water will not dislodge the product or cause it to reactivate. Although these animals may eat a small amount of grass, they will not be able to get enough of the product to cause a health hazard.

Great product, but not much of it in this containe

2 months ago
RoundUp is the only surefire way to get rid of weeds in our little patch of ground. I was disappointed in this purchase since it only covered two applications. A little expensive. I bought a bottle of concentrate. I hope I’ll be able to open up this container and close it again securely so that it will work again

Quick Switch Refill

6 months ago
This is a quick and easy refill that simply needs the sprayer switched over from the original bottle. The original bottle is very long lasting that I have not even needed this backup product yet after treating my driveway and sidewalk.
