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.

Tenacity is a great herbicide option for homeowners looking to treat problem weeds that are difficult to get rid of in their lawns. This highly effective weed control is a popular option for homeowners looking to treat a variety of weeds including chickweedclovercrabgrassdandelionfoxtailhenbit and nutsedge
Tenacity Herbicide contains mesotrione, a chemical that prevents the weed from making carotenoid, which protects the chlorophyll from sunlight degradation. Once applied, the mesotrione penetrates the weed through foliar contact and inhibits the carotenoids from protecting the chlorophyll. Soon after, the weed turns white and dies due to chlorophyll loss. Though Tenacity starts to work on contact, it can take up to three weeks for the weed to die.
The active ingredient is Mesotrione 40%


Tenacity Herbicide contains a unique formula for targeting and controlling weeds in cool- and warm-season turfgrasses. It controls both pre- and postemergent broadleaf grasses and weeds and doesn’t harm newly seeded turf. Other target weeds include:

  • Thistle
  • Barnyard grass
  • Carpetweed
  • Dandelion
  • Nutsedge
  • Chickweed
  • Crabgrass
  • Foxtail
  • Goosegrass
  • Henbit
  • Clover
  • Purslane
  • Wild carrot

Tenacity herbicide also controls bentgrass in Kentucky bluegrass and tall fescue turf. It’s also safe to use at seeding to prevent weed germination. Tenacity does not provide effective results on common bermudagrass, seashore paspalum or zoysiagrass.
