Fall Glyphosate Application

This article is brought to you by Keep it Clean!

Protect your investments and help to maintain market access for all by carefully planning and managing pre-harvest glyphosate applications.

Glyphosate is registered for pre-harvest perennial weed control and is not to be used as a desiccant; improper use can leave residues that exceed maximum allowable limits.

When using glyphosate to control weeds pre-harvest, protect your investment and marketability of your crop by following these Keep it Clean! guidelines:

  • Wait until the least mature areas of the crop reach a seed moisture level of less than 30 per cent or less before applying glyphosate. Applying too soon can cause unacceptable residues.
  • Stick to the recommended pre-harvest interval (PHI), which is the wait time between a product application and when the crop can be harvested. PHI can be found on the product's label.
  • Do not apply glyphosate to malt barley. It will not be accepted if treated.
  • Check with your grain buyer before applying pre-harvest glyphosate to oats.

By using glyphosate correctly, you can help to ensure the quality and safety of Canadian canola, cereals and pulse crops, and keep markets open for all.
