Tenacity is a product that can be used pre- and post-emergently for the control of 46 different weeds and grassy weeds, most notably some very difficult to control weeds such as crabgrass, yellow nutsedge, ground ivy and nimblewill. The active ingredient, mesotrione, is derived from a natural compound produced by the bottlebrush plant and inhibits photosynthesis in the targeted plants. This action leaves the affected plants looking bleached and white as they die off. Tenacity treats crabgrass pre-emergently and post-emergently up through the 4-tiller stage but has zero effect on grass seed and newly planted turf, making it the ideal product to use at the time of seeding, giving new grass its best chance to flourish. It is highly recommended a surfactant is used with Tenacity to achieve best results.
