Best Southern Ag Weed Killers in 2026

Liquid Harvest Mesotrione is a very useful herbicide as it prevents crabgrass seed germination and kills broadleaf weeds (dandelion and clover among others) on contact, while allowing certain cool season turfgrass to grow in a weed-free environment.

Liquid Harvest Mesotrione has a 40% active ingredient that inhibits photosynthesis in susceptible plant species. It is distributed throughout the plant after being absorbed by the plants through roots, shoots and leaves.

Liquid Harvest Mesotrione targets 46 broadleaf species of weed and grass. It can combat Barnyard grass, Carpetweed, Chickweed, Clover, Crabgrass (large & smooth), Dandelion, Foxtail, Goosegrass, Henbit, Yellow Nutsedge, Purslane, Thistle, Wild Carrot, and others.

Not your typical weed killer! Mesotrione prevents photosynthesis in plants. It will absorb and start working immediately, however, it can take up to 2-3 weeks before full death occurs on your weeds

Mesotrione must be activated by water. If rainfall hasn’t occurred within 10 days of application, water the area with 0.15 inches of water
