10 Best Pre Emergent For Bermuda Grass 2025 in the United States

Scotts Halts Crabgrass & Grassy Weed Preventer is a granular pre-emergent weed control product designed to cover up to 10,000 square feet, making it suitable for large lawns. One of its main strengths is its long-lasting effect, with a single application in spring preventing crabgrass and other problem weeds throughout the season. This is particularly convenient for users who want a low-maintenance solution to weed control.

Its versatility shines through as it can also be applied in the fall to prevent winter weeds like poa annua, henbit, and chickweed, and even moss. This dual-season application is highly beneficial for year-round lawn care. Another advantage is its resilience to weather conditions; rain, snow, or freezing temperatures won't diminish its effectiveness, adding to its reliability.

The granular formulation is easy to apply but may not be as precise or customizable as liquid formulations for spot treatments. The product's weight and packaging size (20.12 pounds) also mean it may be cumbersome to handle for some users. This product is well-suited for homeowners with large Bermuda grass lawns looking for a straightforward, long-lasting weed control solution.

It is important to note that this herbicide is not suitable for a range of grasses including Bermuda grass, unless applied to dormant Bermuda grass.

It may take 2-3 weeks to see full results, so patience is required.

The herbicide is manufactured by Sanco Industries and is available in a compact, easy-to-handle packaging. Users must also be mindful of its specific application requirements to achieve the best results.
