Commonly known as Tenacity™ - 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. Meso is one of the few herbicides that controls weeds in cool season grasses during the seeding process and provides pre-emergence and some post-emergence control of many weeds.
