10 Best Pre Emergents For Zoysia Grasses 2025 in the United States

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 Turf Builder Triple Action1 is designed for those looking to maintain a thick, green lawn while controlling weeds and preventing crabgrass. It features a combination formula that not only kills existing weeds like dandelion and clover but also prevents crabgrass for up to 4 months. This product is versatile as it can be used on various grass types, including Zoysiagrass, making it suitable for diverse lawn care needs.

One of its strongest points is the coverage area, as a single 33.94 lb. bag can treat up to 12,000 sq. ft., which is beneficial for large lawns. Additionally, the application process is relatively straightforward: apply to a wet lawn with a Scotts spreader and water after 24 hours, ideally in early spring when weeds are actively growing. The active ingredients, Pendimethalin, 2,4-D, and Dicamba, are effective for weed control and prevention.

However, some drawbacks include its inability to kill existing crabgrass and the need for precise application timing to achieve the best results. Moreover, since it requires a spreader for application, it might not be the best option for those without this equipment. Those with smaller lawns might find the large coverage area unnecessary. Despite these minor issues, Scotts Turf Builder Triple Action1 is a comprehensive solution for those looking to enhance their lawn's health while combating common weed problems.
