We're All In This Together.
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.
Five Simple Steps to Keep Your Canola Ready for Export
1. Use Acceptable Pesticides Only
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.
2. Use Pesticides Correctly
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 spraytoswath.ca for more info.
3. Control Blackleg
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.
4. Store Canola Properly
- 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.
5. Do Not Grow De-registered Varieties
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. De-registered varieties include:
- ROUNDUP READY POLISH (B. RAPA): Hysyn 101RR
- BROMOXYNIL TOLERANT: 295BX, Armor BX, Cartier BX, Zodiac BX, Renegade BX
- LIBERTY LINK (B. NAPUS): Exceed, 2631 LL, Swallow, SW Legion LL, SW Flare LL, LBD 2393 LL, Innovator, Independence, HCN 14, Phoenix, 3850, 2153, 3640, 3880, 2163, 2273
- CLEARFIELD TOLERANT: 46A76
