    How Tenacity Herbicide Works

    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.

     

    Tenacity Herbicide Target Weeds

    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

    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.

    Tenacity Herbicide Provides Effective Weed Control

    Use Tenacity herbicide to control selective weeds on turfgrass at home, on the golf course or throughout athletic fields. It starts to work on contact, disrupting photosynthesis and preventing the weed from developing. For postemergence applications, combine Tenacity with a nonionic surfactant to increase the herbicide's effectiveness. When weeds pop up in your lawn or on the golf course, remove the unsightly problem with Tenacity selective herbicide.
