10 Best Lawn Pre Emergents 2026 in the United States

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is designed to stop crabgrass and several other common weeds like barnyard grass, foxtail, and chickweed before they grow. It comes in granule form, which is easy to spread across your lawn, covering up to 14,000 square feet with one bag. The product works best when applied in early spring on a dry lawn, before the grass is mowed 3 or 4 times and before temperatures regularly hit 80 degrees. This timing helps prevent weeds from sprouting while feeding your grass for a quicker green-up after winter.

It is effective even if there’s rain, snow, or freezing weather shortly after application, so you don’t need to worry about weather ruining the treatment. While it controls a good list of weeds, it is primarily targeted at crabgrass prevention. Because it contains fertilizer, it supports lawn health but should be used with care if you have delicate or newly seeded areas to avoid harming those plants.

Some users may find the weight and size of the bag a bit large for small yards, but for bigger lawns, it offers solid coverage and combines weed control with feeding in one convenient product. The product performs reliably for most home lawns looking to prevent crabgrass and maintain healthy grass growth.

The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control is designed specifically for preventing weeds rather than eliminating existing ones. It is effective against a variety of grassy and broadleaf weeds, including crabgrass, poa annua, goosegrass, and henbit, making it versatile for maintaining a clean lawn. The product contains 0.48% prodiamine, a powerful herbicide, and is meant to be applied in early spring and fall, giving you a seasonal approach to weed prevention. Each 40-pound bag covers up to 12,880 square feet, offering extensive coverage for larger lawns or multiple applications.

The DG Pro formulation enhances the product's performance by providing more particles per square inch, ensuring better coverage and effectiveness. Additionally, being made in the USA adds a level of trust and quality assurance to the product. However, it is important to note that this product won't help with existing weeds, so you might need a separate solution for those. Furthermore, care should be taken to apply it correctly to avoid affecting desired plants.

The granular form makes it easy to spread, but handling a 40-pound bag might be cumbersome for some users. This pre-emergent is a robust and effective solution for those looking to prevent a wide range of weeds in their lawn.

Scotts Turf Builder Bonus S Southern Weed & Feed2 is a combination weed killer and lawn fertilizer, designed for southern lawns. It effectively targets a variety of common weeds like dollarweed, clover, and dandelion while also feeding the grass to promote strong root development.

This product is formulated specifically for use on grasses such as St. Augustinegrass, Centipedegrass, Zoysiagrass, and Carpetgrass, ensuring safety for these types of desired plants. With a coverage of 10,000 sq. ft., its 34.48 lb. bag can treat large lawn areas. It's crucial to apply this product to a dry lawn when both grass and weeds are actively growing, followed by immediate watering to activate its ingredients.

Users should be cautious as it is only suitable for specific grass types and may not be effective or safe for use on other varieties. Its powder form might not be as convenient for everyone, and care must be taken to follow application instructions properly to avoid damaging the lawn.
