Keep It Clean – Export Ready

Canada exports 90% of the canola we produce, and shipments containing even the smallest amount of unacceptable residues or de-registered varieties can be rejected, causing millions of dollars in losses and placing future business at risk. Don’t spoil the bunch. Produce export-quality canola and protect Canada’s reputation as a quality supplier by following these guidelines closely.
Meeting export standards
Canada exports 90% of the canola we produce, and our global customers won’t accept anything less than squeaky-clean seed. Producing export quality canola starts with planting the best seed and managing it carefully.

Why MRLs matter
Maximum Residue Limits are a big factor in international trade. Watch this video to find out why you should consider MRLs when making pest management decisions.

Importers are always on the lookout for unwanted residues, so follow these guidelines closely. Shipments that contain even the smallest amount of de-registered varieties, pesticide residues or blackleg residues just don’t float anymore. Importing countries will turn them away, causing millions of dollars in losses and placing future business at risk.

Five simple steps to get your canola ready for export


Only apply pesticides that are registered for use on canola in Canada and won’t create trade concerns. Registration of a pesticide doesn’t guarantee that it is acceptable to export customers. One challenge is that registration can pre-date the establishment of maximum residue limits (MRLs) in major export markets, and in some cases this can create a market risk. Talk with your grain buyer before you spray to ensure the pesticides you’re using are acceptable to your customers.

DonotuseDO NOT USE:

  • HERBICIDE: Quinclorac (e.g. Accord, Clever, Facet and Masterline Quinclorac)
    Questions remain about whether canola treated with the active ingredient quinclorac is acceptable in all key export markets for canola. The member companies of the Western Grains Elevator Association and the Canadian Oilseed Processors Association have individually advised that they will not accept delivery of canola grown and harvested in 2017 that has been treated with quinclorac. Residues can occur in canola seed, oil and meal and there is no tolerance established to facilitate trade with ChinaUntil exporters and processors are confident that they can ship quinclorac-treated canola to China without trade concerns, growers are advised to avoid this marketing risk by using other cleavers control methods. Learn more about quinclorac and options for controlling cleavers.
  • HERBICIDE: Fluazifop-p-butyl (e.g. Venture L and Fusion)
    Fluazifop-p-butyl is the active ingredient of grass herbicides Venture L and a component of Fusion. The United States has no tolerance levels established for fluazifop residues in canola seeds.
  • FUNGICIDE: Vinclozolin (e.g. Ronilan)
    Canola tolerances for vinclozolin (the active ingredient in Ronilan) are no longer in place for the United States. Any canola treated with Ronilan is no longer acceptable for shipment to the United States.


  • FUNGICIDE: Metconazole (e.g. Quash)
    Growers will have limited options to sell canola treated with metconazole (the active ingredient in Quash) as several grain buyers have indicated they will not accept canola treated with metconazole in 2017. Residues can occur in canola seed and there is no tolerance established to facilitate trade with China. Residues do not occur in oil or meal. Consult your grain buyer for more information.

Follow the correct rates and timing listed on the label. Stick to the pre‑harvest interval (PHI), since applying the product too close to harvest may result in higher than accepted residue levels in the seed. The PHI (or Spray to Swath Interval) is the number of days that must pass between the last application of a pesticide and swathing or straight combining. Check out the provincial Guides to Crop Protection and visit for more info.

Blackleg infection is initiated by spores being released from infected canola residue or stubble. Follow these practices to keep blackleg from impacting yield and profitability, and to reduce the presence of blackleg on seed.

  • Plant only canola varieties rated R (resistant) or MR (moderately resistant). Rotate varieties to bring a mix of blackleg resistance genes to the field over time
  • Plant certified treated seed.
  • Scout canola fields regularly for blackleg symptoms and prevalence to help determine the effectiveness of your blackleg management plan.
  • Maintain a break between canola crops to allow time for crop residue to decompose. If blackleg becomes established, a minimum break of two to three years is recommended.
  • Consider applying a fungicide if you identify the disease early in the season.
  • Control volunteer canola and other Brassica weeds (stinkweed, shepherd’s purse, wild mustard, flixweed) to prevent blackleg build up during non-canola years.
  • Make sure your storage bins are free of treated seed (which contains pesticides) and animal protein like blood meal and bone meal.
  • Clean bins thoroughly prior to storing canola.
  • Never use malathion to prepare canola for storage or to treat bins used to store canola. Its residue can linger for up to six months, so choose your canola storage bin carefully.
  • Keep canola cool and dry to avoid spoilage and insect issues.

When you sign the mandatory Declaration of Eligibility affidavit at the elevator, you are making a legal assertion that your canola is registered. If it isn’t, you can be held liable for the costs associated with contamination of a bin or shipment.

Do not seed these de-registered varieties or any seed produced from them, and don’t deliver them to a Canadian elevator or crushing plant. For treated seed, contact provincial authorities or municipal landfill for disposal.
