Milestone Herbicide is a professional-grade systemic herbicide powered by aminopyralid for long-lasting control of annual, biennial, and perennial broadleaf weeds, invasive species, noxious weeds, select woody plants, and vines. Recognized by the EPA as a Reduced Risk pesticide, Milestone provides exceptional post-emergent activity combined with residual soil control that prevents establishment of susceptible weed seedlings and regrowth of many perennial species. Milestone is widely used for pasture improvement, rangeland management, Conservation Reserve Program (CRP) acres, wildlife habitat restoration, rights-of-way vegetation management, industrial sites, prairie restoration, natural areas, and utility corridors. Its systemic activity moves throughout the plant, including the root system, delivering reliable long-term control while preserving desirable grass species. Unlike many broadleaf herbicides, Milestone offers exceptional flexibility across a wide range of treatment methods, including broadcast spraying, spot treatments, foliar applications, cut-stump treatments, basal bark treatments, dormant stem treatments, and integrated vegetation management programs. It can also be applied to terrestrial vegetation near the water's edge when used according to label directions.

Application Notes

Milestone may be applied as a broadcast spray, spot treatment, aerial application, high-volume foliar spray, low-volume foliar treatment, cut-stump treatment, hack-and-squirt treatment, basal bark treatment, or stem bark treatment depending on the target species and site conditions. Applications should be made to actively growing weeds under favorable growing conditions for optimum performance. For best results, avoid mowing, haying, burning, or disturbing treated vegetation for at least 14 days following application. The addition of a high-quality non-ionic surfactant is recommended under adverse environmental conditions or when treating mature, difficult-to-control weeds.
