10 Best Pre Emergent For Bermuda Grass 2026 in the United States

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is a solid choice for anyone aiming to maintain a healthy Bermuda grass lawn while keeping unwanted weeds at bay. One of its main strengths is its dual function; it acts not only as a pre-emergent weed killer but also provides fertilizer, helping to promote a quick green-up after winter. The active ingredients effectively target common weeds like crabgrass and others, ensuring a cleaner lawn come spring.

Application is straightforward; it’s suggested to be used in early spring before the grass has been mowed a few times, which is crucial for its effectiveness. It can be applied during various weather conditions, including rain or snow, without losing its potency, adding to its convenience. The coverage area is impressive too, with one bag treating up to 15,000 square feet, making it a cost-effective option for larger lawns.

However, it comes with a few drawbacks. For starters, it cannot be used on certain grass types, specifically Dichondra and Bentgrass, which may limit some users. Additionally, timing your application is critical; if you miss the early spring window, you might not get the desired results. While it's designed for a wide variety of weeds, some users might find it less effective on tougher weeds that may require additional treatments.

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.

Prodiamine 65 WDG, a generic form of Barricade, is a solid choice for those looking to control weeds in Bermuda grass and other established turf. Its active ingredient, prodiamine, is effective against a wide range of grassy and broadleaf weeds, including common offenders like crabgrass and chickweed. This makes it particularly beneficial for homeowners and landscapers managing lawns, sod nurseries, and ornamental gardens, as it can help maintain a clean and healthy appearance throughout the growing season.

One of the key strengths of Prodiamine 65 WDG is its residual effect, which provides ongoing protection against weeds after application. With proper timing—ideally applied before weed seeds germinate—users can expect reduced weed pressure for several months. The product also boasts a practical coverage area, allowing users to treat larger spaces efficiently, making it a cost-effective option.

However, there are a few considerations to keep in mind. While Prodiamine is effective, it has a limit on where it can be applied; it should not be used on golf course putting greens, which may restrict its use for some landscapers. Additionally, the granule form requires proper application techniques to ensure even distribution, which might be a bit challenging for those unfamiliar with herbicide application. Another potential drawback is the need to follow the manufacturer's storage instructions closely. Although it has a shelf life of up to three years, improper storage could reduce its effectiveness over time.
