Anderson's Starter Fertilizer with Mesotrione (Tenacity)

Give New Grass Every Advantage.

The first few weeks after seeding determine whether a new lawn reaches its full potential.

During this critical establishment period, young grass seedlings are competing against aggressive weeds for sunlight, water, and nutrients. Anderson’s Starter Fertilizer with Mesotrione combines a premium starter fertilizer with the proven weed control of Mesotrione—the same active ingredient found in Tenacity® herbicide—to provide both the nutrition and early-season weed suppression needed for successful lawn establishment.

Instead of making separate fertilizer and herbicide applications, you can feed your new lawn while suppressing crabgrass and many broadleaf weeds in a single pass.

Why Lawn Professionals Choose Anderson’s Starter Fertilizer with Mesotrione

• Fertilizes and protects at the same time. Apply immediately after seeding to provide essential nutrients while suppressing susceptible weeds during establishment.

• Controls many broadleaf weeds.Helps suppress many common broadleaf weeds before they become established, reducing competition during the most important stage of growth.
• Premium starter fertilizer analysis (21-22-4). High phosphorus levels encourage rapid root development, while methylene urea provides extended nitrogen release for steady growth.
• Uniform SGN 135 homogeneous granules. Every granule contains the complete fertilizer analysis, promoting even nutrient distribution and consistent results across the entire lawn.
• Professional-quality results. Ideal for complete lawn renovations, overseeding projects, and establishing premium cool-season turf.

Important Use Restrictions

For best results, do not use this product when seeding fine fescue varieties if they make up more than 20% of the seed mixture, including the SS6000 mixture, as temporary turf injury may occur.

Do not apply when establishing bermudagrass, bahiagrass, centipedegrass, St. Augustinegrass, or other warm-season turf species, as Mesotrione is intended primarily for use on cool-season turf.

Because this product is designed for cool-season lawn establishment, it is not recommended for use in Florida, where warm-season grasses dominate residential lawns.

Application Rate

Apply immediately after seeding as the final step in your lawn renovation.

Application Rate: 4.3 pounds per 1,000 square feet

One 40-pound bag covers approximately 9,300 square feet.

For the most uniform weed suppression and fertilizer coverage, apply in two perpendicular directions whenever practical.

About Mesotrione

Mesotrione is the active ingredient found in Tenacity® herbicide and is one of the few selective herbicides labeled for application at the time of seeding on most cool-season turfgrasses. It works by suppressing susceptible weeds while allowing desirable turf to establish, reducing early competition and giving new seedlings the best opportunity to develop into a dense, healthy lawn.

Some temporary whitening of susceptible grasses, particularly fine fescue, may occur following application. This cosmetic effect is normal and typically disappears as the turf matures.
