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.

The Preen Garden Weed Preventer is a granule-based product and comes in a 22 lb. bag that can cover up to 3,520 sq. ft., which is quite extensive. One of its major strengths is its ability to prevent new weeds from sprouting for up to 3 months, saving effort on hand-weeding and making it suitable for busy gardeners.

It is also versatile in terms of application as it can be used in spring, summer, or fall, and is safe around over 200 different types of established plants including flowers, vegetables, trees, and shrubs. This flexibility can be particularly beneficial for those with varied garden types and schedules. The product is easy to apply and can serve as a refill for a flip-top applicator, which adds to its convenience.

However, there are some drawbacks. The product is not intended for use on lawns, meaning it is not suitable for those looking specifically for a pre-emergent for Bermuda grass on their lawns. Additionally, its specificity to garden beds rather than lawns limits its use if your main concern is Bermuda grass lawns. The residual effect lasts up to 3 months, which is decent but may require reapplication for year-round protection. Considering these points, the Preen Garden Weed Preventer is ideal for gardeners looking to maintain weed-free garden beds and plant areas, but not the best choice for those needing a solution for Bermuda grass lawns.

Liquid Harvest Mesotrione is a potent herbicide known for its active ingredient, Mesotrione, which is effective against a variety of broadleaf weeds and grasses. It works by inhibiting photosynthesis in susceptible plants and can be used both as a pre-emergent and post-emergent weed killer. The product is especially useful in preventing crabgrass seed germination and eliminating broadleaf weeds, ensuring a weed-free lawn environment.

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. Thus, careful consideration is needed when applying to avoid damaging the desirable grass types. The liquid formulation requires activation with water, and in the absence of rainfall, users need to manually apply water within 10 days for the product to be effective. It may take 2-3 weeks to see full results, so patience is required.

This product covers a broad range of weed species and is suitable for various types of turf grasses such as Kentucky Bluegrass and Tall Fescue. The product is well-formulated for ease of use, and one 32oz bottle can cover a significant area, making it cost-effective. However, due to its limitations on certain grass types, it may not be the best choice for everyone, particularly those with Bermuda grass lawns. 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.
