10 Best Herbicide For Centipede Grass 2026 in the United States

Roundup Weed and Grass Killer₄ is a powerful non-selective post-emergent herbicide designed to kill many tough weeds and grasses down to the root, including dandelion, crabgrass, and poison ivy. Its non-selective nature means it will kill most plants it contacts, so it’s not specifically selective for centipede grass and should be used carefully around desirable plants. The product comes with a Comfort Wand that offers easy, continuous spray application, making it convenient for targeting weeds in flower beds, around trees, patios, driveways, and other hardscape areas. It becomes rainproof in as fast as 30 minutes, which is helpful if the weather is uncertain.

Since it kills all plants it touches, it’s not ideal if you want to keep your centipede grass healthy—this herbicide is more for spot treatments on unwanted weeds or bare areas rather than widespread lawn use. Planting new plants is possible 1 to 30 days after application, depending on the area treated, which provides some flexibility. The product is effective and highly rated, but users should handle it carefully and avoid spraying on grass or other plants they wish to keep.

This product suits homeowners who want to quickly eliminate broadleaf weeds and grasses in specific spots rather than treating an entire centipede grass lawn without damage.

The Spectracide Weed And Grass Killer Concentrate is a non-selective, post-emergent herbicide designed to kill a broad range of weeds and grasses on hard surfaces like patios, driveways, and walkways. Because it is non-selective, it will kill any plant it touches, including desirable grasses like centipede grass, so it should be used carefully in areas where you want to keep your lawn intact. The product is a liquid concentrate that you mix and apply with a tank sprayer, allowing you to cover weeds thoroughly. One standout feature is its fast-acting formula, showing visible results in as little as three hours, which is convenient if you want quick control. It is also rainfast within 15 minutes, meaning light rain or watering won’t reduce its effectiveness shortly after application.

Since this is not a selective herbicide formulated specifically for centipede grass, using it directly on your lawn risks damaging or killing the grass itself. This product is better suited for killing weeds on non-grass areas or for spot treatments where no grass is present. Users looking for herbicides safe for centipede grass may want to consider selective options to avoid harming their lawn. Safety-wise, as with all herbicides, following label instructions carefully is important to protect surrounding plants and the environment.

The Spectracide Weed And Grass Killer Concentrate is designed to kill a wide range of weeds and grasses, making it a non-selective herbicide. This means it will kill most plants it touches, which is important to know if you want to protect centipede grass, as this product can harm it too. It works as a post-emergent herbicide, so it kills weeds and grasses after they have grown rather than preventing them from sprouting. Its fast action shows results in as little as three hours, and it kills the roots, which helps stop weeds from coming back quickly. You apply it by mixing the concentrate with water in a tank sprayer and thoroughly spraying the target plants. It’s rainfast within 15 minutes, so light rain or watering won’t wash it away soon after application.

The product is meant for use on hard surfaces like patios, driveways, and walkways, and around fences or flower beds, which suggests it's best used where you want to clear all vegetation rather than selectively treat your lawn. Because it is non-selective, it’s not the best choice if you want to treat centipede grass specifically without damaging it. If you need to clear areas completely free of any plants, this product works well and covers a large area (over 2,000 square feet per bottle).

Extra caution is needed during application to avoid contact with the centipede grass you want to keep. Safety instructions should be followed closely to protect desirable plants and avoid accidental damage. The product is strong and fast-acting for removing unwanted weeds and grasses on hardscape or non-lawn areas but isn’t tailored for selective weed control in centipede grass lawns.
