SINATE® is a postemergence corn herbicide that controls herbicide-resistant weeds in corn with the LibertyLink® trait. SINATE also provides outstanding crop safety. The powerful one-two punch of topramezone and glufosinate provides punishing efficacy in the fight against herbicide-resistant weeds like waterhemp, Palmer amaranth and giant ragweed. [See SINATE video, field performance, and testimonials.]


  • For use on glufosinate tolerant field corn (grain and silage) and sweet corn containing LibertyLink traits.
  • Field corn containing LibertyLink traits: Emergence up to 24 inches tall/V7 stage of growth. Use drop nozzles for corn 24 to 36 inches tall.
  • Sweet corn containing LibertyLink trait: Emergence up to V6 stage of growth.


  • Contains two effective modes of action to deliver postemergence control of key grasses and herbicide-resistant weeds like waterhemp, Palmer amaranth and giant ragweed.
  • Glufosinate combined with the active ingredient in Impact Herbicide delivers consistent performance on a wide spectrum of grass and broadleaf weeds.
  • The crop safety of topramezone from Impact and the inherent tolerance of the LibertyLink corn trait to glufosinate helps SINATE deliver outstanding crop safety.
