Liquid Harvest Mesotrione - 8oz - Mesotrione Concentrate (Compare to Tenacity) - Pre and Post-Emergent Weed Killer for Lawn and Turf Grasses

Mesotrione, a potent herbicide, immediately absorbs and starts working upon application, yet it may take 2-3 weeks for full weed death. Activation requires water; if no rainfall occurs within 10 days, apply 0.15 inches of water.
Targeting 46 broadleaf species and grasses, including Barnyard grass, Carpetweed, Chickweed, Clover, Crabgrass, and Dandelion, Mesotrione is versatile.
Suitable for Kentucky Bluegrass, Centipede grass, Buffalo grass, Tall Fescue, Perennial Ryegrass, Fine Fescue, and St. Augustine Grass (sod only). Avoid Bentgrass, Poa annua, kikuyugrass, zoysiagrass, seashore paspalum, and bermudagrass. Apply Mesotrione on dormant bermudagrass to eliminate weeds.
Mesotrione inhibits photosynthesis in susceptible plants, distributing throughout the plant via roots and leaves. It's an effective herbicide preventing crabgrass seed germination and eliminating broadleaf weeds on contact, encouraging the growth of certain cool-season turfgrass in a weed-free environment.
