10 Best Chemical Crabgrass Killers 2025 in the United States

The Scotts Turf Builder Triple Action1 offers a comprehensive solution for anyone seeking to maintain a healthy, weed-free lawn. This product stands out with its three-in-one formula that not only kills common weeds like dandelions and clover but also prevents crabgrass for up to 4 months while simultaneously fertilizing the lawn. This combination can be very efficient for maintaining a lush, green yard without the need for multiple separate treatments.

The product is designed for use on a variety of common lawn grasses, including Bahiagrass, Centipedegrass, and Kentucky Bluegrass, making it quite versatile. It comes in granular form, which is easy to apply using a Scotts spreader, and requires watering in after 24 hours for best results. Timing the application in spring when dandelions are actively growing is crucial for effectiveness. However, it's important to note that this product won't kill existing crabgrass, which may require additional treatments if already present.

Additionally, it's not available for purchase in several regions, including AK, HI, PR, GU, and VI. Environmentally, the impact of such chemical treatments should be considered, especially regarding potential effects on non-target plants and soil health. Users should also consider the ease of use and follow the application instructions carefully to avoid potential misapplication. The Scotts Turf Builder Triple Action1 is a strong contender for those who want a multipurpose product that handles weeds, crabgrass prevention, and lawn feeding in one package.

The BASF Drive XLR8 Crabgrass Killer is a liquid concentrate herbicide with quinclorac as its active ingredient, known for targeting both grassy and broadleaf weeds effectively. It features a unique water-based formulation that promotes quick absorption into plants, delivering visible results in a short time. One key benefit is its extended control, offering up to 30 days of protection after application, which reduces the need for frequent treatments and helps maintain a weed-free lawn for longer periods.

This herbicide is effective on various turf types, including cool-season and warm-season grasses, making it suitable for a range of lawn settings such as residential yards, golf courses, and commercial turf areas. It targets a broad spectrum of weeds, including crabgrass and common broadleaf weeds like clover and dandelion. The product becomes rainfast within an hour, enhancing ease of use by minimizing concerns about rain washing it away shortly after application.

Users need to follow proper safety precautions when using this herbicide, including wearing protective clothing and gloves. Some state restrictions apply—for example, in New York, it is only permitted for spot treatments. Adhering carefully to label instructions is important to avoid environmental harm and ensure safety. Customer feedback indicates satisfaction with its effectiveness and versatility, though some users may find the handling and application guidelines somewhat demanding. This product suits lawn owners seeking a powerful, long-lasting solution for crabgrass and other weeds, provided they are comfortable with the necessary safety measures.

The Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is designed to serve a dual purpose: preventing crabgrass and other listed weeds while fertilizing your lawn for a fast green-up after winter. It is most effective when applied early in the spring to a dry lawn before the temperature regularly hits the 80s. One of its standout features is its extensive coverage, capable of treating up to 15,000 sq. ft., making it suitable for larger lawns.

However, it's important to note that it should not be used on Dichondra and Bentgrass lawns as it may harm these types of grass. The product's formulation ensures that adverse weather conditions like rain or snow won't impact its effectiveness, which adds to its ease of use. While it is efficient in preventing a wide range of weeds, users should be aware of the environmental impact of using chemical treatments on lawns.

This product offers convenience and reliability for those looking to both nourish their lawn and keep crabgrass at bay, provided it is applied at the correct time and on compatible lawn types.
