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 biotypes of kochia resistant to Group 2, 4, and 9, which makes it a great tool for resistance management and sustainability.
  • Certitude helps to sharpen the performance of glyphosate on challenging weeds such as kochia, volunteer canola and wild buckwheat.

Application Tips

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

  • Apply as a tank mix with glyphosate
  • 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)

Mixing in chem handlers with the new Certitude Handling Tool

This new funnel tool lets you pour and rinse the Certitude Part A container directly in the chem handler. Here’s how to use it:

1. Affix the funnel tool to the Certitude A container.

2. Position the funnel and Certitude A container above the center knife system on the chem handler.

3. Add Certitude A component and continue to agitate until visibly dispersed.

4. Run water for a controlled rinse of the Certitude A container.

5. Important: Do not discard the funnel. It can be used for future Certitude mixing or for affixing to other containers for chem handler rinsing.
