7 Best Granular Crabgrass Killers 2025 in the United States

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is designed to stop crabgrass and feed your lawn simultaneously. One of its primary strengths is its dual function as both a pre-emergent weed killer and a fertilizer, which helps in achieving a lush green lawn quickly after winter. It covers a substantial area of 15,000 sq. ft., making it suitable for large lawns. The product is effective against various weeds including crabgrass, barnyard grass, and chickweed.

Application is straightforward; it should be applied in early spring before the 3rd or 4th mowing and before temperatures consistently reach the 80s. Another significant advantage is its rainfastness, meaning rain, snow, or freezing conditions post-application will not diminish its effectiveness. However, it is crucial to note that this product is not suitable for lawns with Dichondra and Bentgrass. Weighing 40.05 lb., it might be a bit cumbersome for some users to handle.

Nevertheless, its ease of application and broad coverage area make it a convenient choice for most homeowners looking to prevent crabgrass and nourish their lawn simultaneously.

Scotts Halts Crabgrass & Grassy Weed Preventer is designed to prevent weed germination and is effective for a wide range of common lawn weeds such as crabgrass, foxtail, and chickweed. The product comes in a 20.12-pound bag and covers up to 10,000 square feet, making it suitable for both small and large lawns. Its granular form makes it easy to apply using a spreader.

Application can be done in early spring or fall, and the product is rainfast, meaning rain, snow, or freezing weather post-application will not affect its performance, making it quite versatile and convenient. However, it is not suitable for all grass types, specifically Dichondra or Bentgrass, which may limit its use for some users. The product is designed for pre-emergent weed control, meaning it prevents weed seeds from germinating but will not kill existing weeds. This requires timely and consistent application.

Scotts Halts is a reliable choice for those looking to maintain a weed-free lawn, provided they follow the specific application guidelines.

The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control is designed to prevent weed growth rather than eliminate existing weeds. It contains 0.48% prodiamine, a professional-grade herbicide, making it effective against a wide range of grassy and broadleaf weeds such as crabgrass, poa annua, goosegrass, and henbit. One of its notable strengths is its extensive coverage area, with an 18-pound bag treating up to 5,800 square feet, making it suitable for larger lawns or gardens.

Additionally, the DG Pro formulation ensures a higher particle density per square inch, which enhances its performance and distribution across the treated area. The product is ideally applied in early spring and fall, which aligns with the most effective timing for pre-emergent herbicides. However, a potential drawback is that it is not rainfast, meaning that rain shortly after application could diminish its effectiveness. Users may need to plan their application around dry weather conditions to ensure the product works optimally.

Considering ease of application, the granular form is user-friendly and can be spread using a standard lawn spreader. This product is best suited for users seeking to prevent future weed growth in large areas and who can manage the timing of their application to avoid rain.
