10 Best Pre Emergents For Zoysia Grasses 2026 in the United States

The Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food offers a comprehensive solution for controlling weeds and fertilizing your lawn. One of its primary strengths is its dual function: it stops various weeds such as crabgrass, barnyard grass, and chickweed before they emerge, while also feeding the grass to promote a quick green-up after winter. This makes it particularly beneficial for those looking to maintain a healthy zoysia lawn.

The active ingredient is effective when applied early in the season, ideally before temperatures consistently reach the 80s, ensuring that it integrates well with the seasonal growth patterns of zoysia grass. The formulation is granular, which is easy to apply on a dry lawn, and the product claims to be resilient against varying weather conditions post-application, making it user-friendly for a broad audience.

A notable advantage is its extensive coverage area, with one 40.05 lb. bag treating up to 15,000 square feet, which is quite efficient for larger lawns. However, it should not be used on certain grass types like Dichondra and Bentgrass, limiting its versatility. The product's residual control feature is decent, ensuring prolonged weed prevention throughout the season. This product would be best suited for homeowners with zoysia grass seeking an all-in-one pre-emergent weed preventer and lawn food, keeping in mind its limitations on specific grass types.

Scotts Turf Builder Weed & Feed3 is a combination weed killer and lawn fertilizer suitable for various types of grass, including Zoysiagrass. It contains active ingredients 2,4-D and Mecoprop, which are effective in controlling over 50 types of listed weeds such as dandelions and clover. The product is in granule form and should be applied to a wet lawn when weeds are actively growing, with temperatures between 60°F and 90°F. This ensures the product is most effective in killing existing weeds and promoting a thicker lawn.

A single 14.29 lb. bag covers an area of 5,000 sq. ft., making it suitable for medium-sized lawns. One of the major strengths of this product is its dual action of feeding the lawn while also controlling weeds, which helps maintain a healthy and lush appearance.

However, it seems to lack specific pre-emergent action, meaning it may not prevent new weeds from sprouting. Additionally, the product is not available in Florida, which could be a limitation for users in that region. The need for specific application conditions (wet lawn and particular temperatures) might also be a constraint for some users. Despite these drawbacks, Scotts Turf Builder Weed & Feed3 is a solid choice for those looking to improve their lawn’s health and appearance by tackling existing weeds and fertilizing grass simultaneously.

Scotts Halts Crabgrass & Grassy Weed Preventer is a granular pre-emergent weed killer designed for use on all grass types (excluding Dichondra and Bentgrass). It is particularly effective in preventing the germination of a wide range of lawn weeds such as crabgrass, foxtail, spurge, and various others depending on the season. This product is most effective when applied in the early spring or fall, and its performance is not affected by subsequent rain, snow, or freezing temperatures.

The granule formulation makes it easy to apply, and one 20.12 lb. bag covers a substantial area of 10,000 sq. ft., making it an excellent choice for larger lawns. However, users should note that it is a preventive treatment rather than a solution for existing weeds, so timing is crucial for best results.

The product is made in the USA by The Scotts Company LLC and has been available since October 2020. This pre-emergent is particularly well-suited for people looking for a reliable, long-lasting solution to prevent weed germination in their lawns.
