What customers say
Customers highly value this professional grade herbicide for its targeted effectiveness against tough grassy weeds like Bermuda grass and crabgrass. The core theme centers on its exceptional value due to the high concentration, allowing large area coverage from a single bottle. Success hinges on diligent application; users report dramatic results, with weeds yellowing within two weeks, but only when paired with a nonionic surfactant. Those who follow this mixing requirement achieve thorough, long lasting weed control. While it acts systemically rather than instantly, the powerful, economical performance solidifies its reputation as a top tier solution for serious lawn care.
