9
7.4/10 our score
Features
- 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
- 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.
- For use in Kentucky Bluegrass, Centipede grass, Buffalo grass, Tall Fescue, Perennial Ryegrass, Fine Fescue, St. Augustine Grass (grown for sod only). DO NOT apply this product on Bentgrass, Poa annua, kikuyugrass, zoysiagrass, seashore paspalum, or bermudagrass. Mesotrione can only be used on bermudagrass that is still dormant when trying to remove weeds or target grasses from it. If the bermuda is only semi dormant you will see whitening and damage to the bermuda.
- 4 - 8 oz. per 30 gallons of water per acre, use a Surfactant to Increase Effectiveness and be sure to read label for full instructions
- 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.
