Manufactured by Syngenta, 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. It is absorbed by plants through the roots, shoots and leaves and distributed throughout the plant by both xylem and phloem translocation.
KEY FEATURES: Weeds controlled include crabgrass, ground ivy, yellow foxtail, yellow nutsedge and nimblewill. It also controls unwanted bentgrass. Provides post-emergent control of tough-to-control weeds. Controls weeds at seeding reducing weed competition.
KEY BENEFITS: Prevents and controls crabgrass pre or post up to four tillers. Eliminates weeds at seeding so new grass can flourish.
Tenacity is a systemic pre-emergence and post-emergence herbicide for the selective contact and residual control of weeds in turfgrasses.
When applied as a pre-emergent, weeds absorb Tenacity during emergence from the soil.
Target pests: Barnyardgrass, Carpetweed, Chickweed, Clover, Crabgrass (large & smooth), Dandelion, Foxtail, Goosegrass, Henbit, Yellow Nutsedge, Purslane, Thistle, Wild Carrot and others
