Kills Crabgrass, Yellow Foxtail, Yellow Nutsedge, Bentgrass, Clover, Dandelion, Chickweed, Nimbleweed, and many more tough weeds in turf grass. Mesotrione 40% Herbicide 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 Mesotrione 40% during emergence from the soil. Dry conditions following application may reduce the pre-emergence activity. If rainfall (0.15 inches) has not occurred within 10 days after a pre-emergence application, activate with 0.15 inches of irrigation.When used as a post-emergent, Meso 4SC weed killer is absorbed by susceptible weeds through foliar contact and soil absorption. Foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application is required after two to three weeks for improved post-emergence weed control. What is the mode of action of Mesotrione 40% herbicide? Mesotrione 40% inhibits a plant enzyme called HPPD that is essential to photosynthesis and prevents the formation of carotenoids in susceptible plant species. Without carotenoids, light energy and by-products of photosynthesis will destroy chlorophyll and cell membranes.
This results in bleaching of leaves followed by necrosis and death of the plant. How quickly does Mesotrione 40% work?
Once absorbed, Mesotrione 40% quickly translocates throughout the plant. Weed growth is suppressed soon after application, as photosynthesis is disrupted.The death of the plant usually occurs within two to three weeks. What turf species can Mesotrione 40% be applied to? Mesotrione 40% can be applied to many of the turf types commonly found on fairways, roughs, or for sod production, such as Kentucky bluegrass, perennial rye grass, tall fescue, fine fescue, centipede grass, and St. Augustine grass (it will turn SA Grass tips white for about 2 weeks or first mow). Lower use rates are recommended for perennial rye grass, fine fescue, and St.
