7 Best Granular Crabgrass Killers 2026 in the United States

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.

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.

Spectracide Weed Stop for Lawns + Crabgrass Killer is a liquid concentrate designed to kill crabgrass and over 470 other types of weeds without harming your lawn when used as directed. Its active ingredients are effective against both broadleaf and grassy weeds, making it a versatile choice for general lawn weed control. The product comes in a 32-ounce bottle with a hose-end sprayer, which makes application straightforward and convenient – just attach it to your garden hose and flip the switch to spray. This feature is great for covering larger areas without the mess of granular products.

It is recommended to apply right when you first notice crabgrass for the best results. Once applied, the formula becomes rainproof in about 3 hours, so light rain won’t wash it away, adding to its reliability. Since it is a liquid concentrate rather than granular, coverage depends on careful spraying to avoid missing spots or overapplication. Users may need to estimate the amount needed for their lawn based on experience, as the coverage area per bottle is not explicitly defined. This product suits those seeking an easy-to-use, effective crabgrass killer that also controls many other weeds, with timely application and proper spraying technique enhancing its performance.
