Authority® Assist

Small-seeded broadleaf weeds and grasses can steal yield from soybeans. Apply Authority® Assist herbicide with Grass Assist as your foundation herbicide. It lowers the hammer on glyphosate-tolerant summer weeds like lambsquarters, pigweed, nightshade and kochia, as well as suppresses foxtail, fall panicum, nutsedges and other invasive grasses.

  • Multiple modes of action
  • Grass Assist for added grass control
  • Very soluble so it works well with light rain
  • No pH restrictions, so there’s low risk for carryover to corn
  • Complements low-cost, pre-grass herbicides in conventional soybean weed management programs
