Tenacity herbicide can be used for pre- and post-emergence control of more than 46 broadleaf weed and grass species. Its active ingredient, mesotrione, is based on a naturally occurring compound produced by the bottlebrush plant (Callistemon citrinus) that inhibits photosynthesis in susceptible plant species. It is absorbed by plants through the roots, shoots and leaves and distributed throughout the plant by both xylem and phloem translocation.
Weeds controlled include crabgrass, ground ivy, yellow foxtail, yellow nutsedge and nimblewill. It also controls unwanted bentgrass.
Provides post-emergent control of tough-to-control weeds
Controls weeds at seeding reducing weed competition
Prevents and controls crabgrass pre or post up to four tillers
Eliminates weeds at seeding so new grass can flourish.
Rate: For pre-emergent and post-emergent applications, apply 4 to 8 ounces of Tenacity per acre in at least 30 gallons of water per acre. For spot treatments, mix 0.33 ounces (0.5 teaspoon) of Tenacity Herbicide in 1 gallon of water to treat 1,000 square feet. For more specific application rates please refer to label.
Tenacity Herbicide may be applied when soil temperatures are around 55 degrees or higher. Do not apply when air temperature exceeds 85 degrees. Your target temperature range will depend on whether you are using Tenacity for pre-emergent or post-emergent applications. This is typically between 65-85 degrees.
