Strong Feeding and Proven Grub Control — All-Season Performance in One Application.
Shaw's 21-0-4 50% SurfCote Merit 20 combines the trusted grub-control power of Imidacloprid (Merit) with a high 21% nitrogen analysis and 50% SurfCote controlled-release technology — delivering outstanding summer results from a single bag. While the 7-0-0 Merit targets customers who want grub control without extra nitrogen, Shaw's 21-0-4 Merit is built for programs that want strong, visible feeding results alongside comprehensive insect protection.
With half the nitrogen SurfCote-coated for extended release, this product provides both an immediate green-up and a long-term feeding window. Potassium at 4% supports root development, heat tolerance, and disease resistance. Imidacloprid moves systemically through the soil to reach grubs in the root zone before they can cause irreversible turf damage. It's a versatile, dual-purpose product ideal for spring-to-early-summer applications when both fertilizing and grub prevention are priorities.
