What Is Tenacity, And What Does It Do To Grasses And Plants?

Does Tenacity Kill Grass?

Tenacity is a herbicide that’s used to kill weeds. It works by penetrating the weed’s protective waxy cuticle, which allows it to enter the plant and disrupt its growth.

This eventually leads to the death of the weed. Tenacity can be used on both warm-season and cool-season grasses, as well as on other plants.

This highly effective systemic pre- and post-emergent herbicide are designed to selectively target over 46 broadleaf and grassy weed species in your turfgrass, making it an excellent choice for anyone who wants to maintain a beautiful, healthy lawn.

The active ingredient in Tenacity Herbicide, mesotrione 40%, works by targeting the weeds at the cellular level. It prevents photosynthesis in targeted weeds, effectively stopping them from growing.

And because the herbicide is systemic, it penetrates the leaves, stems, and roots of weeds to kill them from the inside out.

The truth is that there is no clear answer to this question. While high concentrations of Tenacity can negatively affect lawns, it all comes down to how much is being used. If used correctly and in moderation, Tenacity can improve the health and vitality of your lawn by providing nutrients and promoting the fast and vigorous growth of grass blades.

Overall, selective herbicides like Tenacity play an essential role in managing unwanted pests in the lawn without harming other plants or compromising the health of your grass.
