  • Provides post-emergent control of tough-to-control weeds

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.
