Whetstone Herbicide delivers powerful, season-long control of over 185 broadleaf weeds, invasive species, and certain woody plants and vines. Designed for use in bareground areas, rights-of-way, and grazed sites, Whetstone features the active ingredient aminopyralid—known for its selectivity toward desirable grasses while eliminating tough weeds like thistles and legumes.
Ideal for both pre- and post-emergent applications, Whetstone is a low-use-rate, tank-mix-friendly solution that enhances bareground treatments and minimizes herbicide resistance. Registered under the EPA’s Reduced Risk Pesticide Initiative, it offers dependable residual control with unmatched flexibility.
