A reliable partner for superior, yet selective, control of numerous broadleaf weeds, vines, and woody plants


Performance Highlights

As a flexible, pre- and post-emergent product, Alligare’s Whetstone is a tank-mix friendly formula that provides residual control of invasive and noxious vegetation in a variety of settings.

  • Broad spectrum control of 185 annual, biennial, and perennial weeds and brush
  • Provides extended pre- and post-emergent control of susceptible species
  • Approved for treating vegetation in areas grazed by livestock, with no restrictions
  • Increases weed spectrum of broadleaf species when included in bare-ground applications
  • Registered under the EPA’s Reduced Risk Pesticide Initiative


Though not classified as a hazardous substance or mixture and the product has no grazing restrictions as such, applicators and end-users should know that waste produced from animals consuming grasses or hay treated with animopyralid may retain enough active ingredients to harm sensitive broadleaf plants. Applicators and end-users should carefully follow product labels regarding warning s or restrictions for manure use.
