10 Best Pre-Emergent Herbicides 2025 in the United States

The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control is designed to stop weeds before they start, covering up to 5,800 square feet with one 18-pound bag. It uses 0.48% prodiamine, a strong active ingredient effective against common grassy and broadleaf weeds like crabgrass and henbit. This product is best applied in early spring or fall, aligning well with typical pre-emergent timing to prevent weed seeds from sprouting.

Its granular form with a DG Pro formulation means you get many small particles per square inch, which helps with even coverage and reliable performance. Made in the USA, it’s suitable for a variety of soil types, but you should always check local guidelines to ensure it fits your specific lawn or garden conditions. One important note is that this product won’t remove existing weeds — it only stops new ones from growing, so it’s not a solution if you already have a weed problem.

When seeking a pre-emergent herbicide that covers a large area with professional-grade effectiveness and does not require addressing existing weeds, this product represents a solid choice. As with any herbicide, use caution to avoid harming nearby plants and follow safety instructions carefully.

Scotts Halts Crabgrass & Grassy Weed Preventer is a solid choice for those looking to maintain a weed-free lawn. One of its key strengths is its ability to prevent the germination of various common weeds such as crabgrass, foxtail, and spurge.

The product is easy to apply, either in early spring or fall, and is effective regardless of weather changes after application, which adds to its convenience for users.

However, there are some considerations to keep in mind. While it is compatible with most grass types, it cannot be used on Dichondra or Bentgrass, which may limit its use for some homeowners. Additionally, it’s important to note that while the product is designed to be safe for lawns, users should still follow the application instructions carefully to minimize any potential environmental impact.

In terms of safety, generally, users report that the product is safe when used as directed, but there may be specific guidelines to follow, especially in areas with unique ecological concerns. The formulation is granulated, which is user-friendly, but requires proper distribution for optimal effectiveness.

It’s best suited for homeowners with common grass types who want an effective solution to keep their lawns looking pristine without the hassle of constant weeding.

However, it is not suitable for use on flower seeds, lawns, vegetable gardens, or any food-producing plants, which limits its application areas.

The 10-pound bag covers a substantial area of 1,630 square feet, making it efficient for larger garden spaces.
