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 Ortho GroundClear Year Long Vegetation Killer2 Concentrate is a strong non-selective, post-emergent herbicide that quickly kills existing weeds and grasses, then prevents any plant regrowth for up to one year. This makes it ideal for areas where you want no plants at all, such as driveways, sidewalks, or gravel patches rather than on your centipede grass lawn. It works fast and becomes rainproof within an hour, which is handy if you expect wet weather shortly after application.

The concentrate mixes with water and is applied via a sprayer, covering up to 3,200 square feet from one 2-gallon container, offering good value for large areas. However, because it is non-selective, it will kill any vegetation it touches, including desirable grasses like centipede grass, so it’s not suitable if you're trying to protect or treat active lawn areas. Safety-wise, as with most strong herbicides, care is needed to avoid drift onto plants you want to keep and to follow label instructions closely.

In summary, this product is ideal for clearing and preventing unwanted vegetation on hard surfaces or bare soil but should be avoided on centipede grass if you want to maintain a healthy lawn.

The Roundup Weed & Grass Killer₄ Refill is a powerful herbicide that targets tough weeds and grasses by killing them down to the root, including common nuisances like dandelions, crabgrass, and poison ivy. It's designed for use around flower beds, trees, driveways, patios, and other outdoor areas, making it versatile for many garden and lawn spots. This product is non-selective, meaning it will kill most plants it touches, so care must be taken when applying it near your centipede grass or other desirable plants.

It acts quickly, becoming rainproof within 30 minutes and showing visible results within hours, which is helpful if you need fast weed control. The application comes as a liquid spray, which is easy to use, and the refill format is convenient if you already have the original sprayer. Because it is non-selective, it is not ideal if you want to protect specific lawn types like centipede grass without damage. Additionally, planting new plants can be done 1 to 30 days after use, following recommended guidelines.

Roundup contains active ingredients that require careful handling and following instructions to prevent unwanted harm to plants or people. This herbicide is most effective for spot treatments where you want to clear out unwanted weeds and grasses quickly and are prepared to avoid contact with your centipede grass or other valuable plants.
