Round Up® Ready to Use Weed & Grass Killer. FastAct technology. Weed & Grass Killer. Rainproof in 10 minutes. Visible results in 3 hours. Kills the roots guaranteed*. Net 1.25 gal (160 fl oz/4.73l) Product facts: Kills all types of weeds & grasses. Covers up to 375 sq. ft. Treats more than 1300 weeds. How it works. Glyphosate is absorbed by the weed's leaves. It moves through the weed to the root, stopping the function of an essential enzyme found in plants, but not humans or animals. Weeds die, root and tall - so they don't grow back. Kill only what you spray. Any product not absorbed by the plant breaks down without moving in or on the soil to untreated plants. Weeds begin to yellow and wilt within 3 hours with complete kill in 1 to 2 weeks. Where to use. In flower beds & vegetables gardens. Around shrubs & trees. On patios, walkways & driveways, gravel or much beds. Along fences & foundations. Edging around foundations and retaining walls. Visit Roundup website to learn more about the Roundup family products.
