Gowan Canada Announces INSIGHT® 339SC Herbicide's Label Expansion to Include Control of Wild Oat and Volunteer Canola in Addition to Lamb’s Quarters, Wild Buckwheat, and Red Root Pigweed Upgrade to Control from Suppression

  • New PPO inhibitor Group 14 mode of action herbicide for Canada
  • Ultra-fast and consistent pre-seed burndown of wild oats and select broadleaf weeds
  • INSIGHT® offers growers another solution to manage herbicide resistance


WINNIPEG, Manitoba, November 14, 2022 INSIGHT® 339SC Herbicide, powered by Tergeo®, is a new active ingredient from the Group 14 mode of action category. After thoroughly reviewing INSIGHT's demonstrated efficacy, this month, the label expansion was granted through PMRA. INSIGHT provides wheat and corn growers with a fast-acting solution to their pre-seed burndown strategy. However, what truly sets INSIGHT apart is the exceptional control of wild oats compared to any pre-seed burndown herbicide in the market today.


"It was essential that control of wild oats be on the label from the start. With the incidence of biotypes of wild oats resistant to other modes of action increasing across Canada, the need for solutions to this expanding problem are immediate", said Dale Ziprick, Product Manager for Gowan Canada. In addition to wild oat, INSIGHT will also control an array of broadleaf weeds, including volunteer canola, kochia, lamb’s quarters, wild buckwheat, and red root pigweed.


INSIGHT 339SC is registered as a pre-seed burndown herbicide in spring wheat and corn and will be available for use in the 2023 growing season. Tergeo® is a new molecule discovered by Korean agrochemical company FarmHannong Co., Ltd. and has been jointly developed with Ishihara Sangyo Kaisha, Ltd globally. Tergeo® is a registered trademark of Ishihara Sangyo Kaisha, Ltd.
