Benefits of Certitude

  • Certitude contains the active ingredients topramezone (Gr 27) and bromoxynil (Gr 6), to provide both contact and systemic properties.
  • Certitude drastically improves the management of tough-to-control weeds such as kochia and volunteer canola, including glyphosate-resistant biotypes.
  • Certitude controls group 2, 4, and 9 resistant biotypes of kochia, which makes it a great tool for resistance-management and sustainability.
  • Certitude helps to sharpen the performance of glyphosate on challenge weeds such as kochia, volunteer canola, and wild buckwheat.

To optimize weed control activity when applying Certitude®, follow these guidelines:

  • Always add adjuvant (Merge®).
  • Use a minimum of 5 gal/ac but 10 gal/ac helps maximize coverage in dense weed areas.
  • Should the product freeze, agitate or mix contents well before use.

When to Apply

  • Certitude should only be applied prior to planting.
  • Do not apply if heavy rain is forecast.
  • Certitude can be applied when broadleaf and grassy weeds are at or between the cotyledon and 4-leaf stages (up to the 6-leaf stage for volunteer canola).
