The bottom line: it delivers visible control without harming many desirable cool-season turfgrasses when used as directed, but it requires activation by rainfall or irrigation and patience for full results. This review explains what it kills, which grasses are safe, and practical limits to expect from an 8oz bottle.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive ingredient:\u003c\/strong\u003e Mesotrione acts by inhibiting photosynthesis, which stops weed growth and leads to plant collapse over a few weeks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast uptake:\u003c\/strong\u003e The concentrate is absorbed immediately at application, beginning activity quickly while full visible control can take 2-3 weeks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad spectrum:\u003c\/strong\u003e Labeled for control of 46 broadleaf species and some grasses including Barnyard grass, Carpetweed, Chickweed, Clover, Crabgrass, and Dandelion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivation requirement:\u003c\/strong\u003e Needs 0.15 in of water within 10 days to activate if rainfall does not occur, so irrigation planning matters after treatment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTurf compatibility:\u003c\/strong\u003e Safe for many cool-season turfgrasses such as Kentucky Bluegrass, Tall Fescue, Perennial and Fine Fescues, and Centipede when applied correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrevention benefit:\u003c\/strong\u003e Prevents crabgrass seed germination as well as eliminating existing broadleaf weeds when used at recommended timings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product is aimed at homeowners, landscapers, and groundskeepers managing cool-season lawns who need a selective herbicide to reduce broadleaf weeds and some grassy weeds without damaging most desirable turfgrasses listed on the label.
