$79.99
RightLine Mesotrione 4 SC is a highly effective, selective herbicide designed specifically to tackle tough broadleaf and grassy weeds while remaining incredibly gentle on desirable cool-season grasses. Whether you are seeding a brand-new lawn or maintaining established turf, this versatile formula provides both immediate weed control and reliable soil residual protection to keep invasive species from bouncing back.
Key Benefits
-
Perfect for New Seedings: Unlike many traditional pre-emergent herbicides that stop new grass seed from germinating, Mesotrione 4 SC can be applied during or right after seeding cool-season varieties like Kentucky Bluegrass, Perennial Ryegrass, and Tall Fescues to keep the site weed-free while your lawn establishes.
-
Highly Visible Results: After application, targeted weeds stop producing chlorophyll and turn distinctly white. This bleaching effect serves as a visual confirmation that the herbicide is actively shutting down the weed’s growth.
-
Versatile Application Sites: Labeled for use on both residential and commercial properties, including home lawns, athletic fields, parks, cemeteries, and sod farms. (Note: It is not labeled for use on golf course putting greens).
-
User-Friendly Formulation: The high-concentration Suspension Concentrate (SC) liquid features a low-odor profile and mixes seamlessly into tank blends for smooth, customizable applications.
