The Dow AgroSciences Milestone Specialty Herbicide is designed to tackle noxious and invasive weeds, making it a strong choice for those dealing with tough, unwanted vegetation. The active ingredient, Aminopyralid, is highly effective in targeting broadleaf weeds while sparing grasses and other non-target plants, which makes it a selective herbicide.
