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.
