Keep It Clean

Meeting export standards
Canada exports 90% of the canola we produce, and our global customers won't accept anything less than squeaky-clean seed. This video explains what importers look for and our shared responsibility to Keep it Clean.

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.

Five simple tips
Export-quality canola starts with planting the best seed and managing it carefully. Here's how...

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 TIPS TO GET YOUR CANOLA READY FOR EXPORT

Pesticide Timing Icon1. USE PESTICIDES AT THE CORRECT RATE, TIMING AND PRE-HARVEST INTERVAL

Only apply pesticides registered for use on canola, and always follow the 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.

Unregistered Pesticides Icon2. DO NOT USE UNREGISTERED PESTICIDES OR THOSE WITH UNACCEPTABLE RESIDUES

All herbicides, insecticides and fungicides must be registered for use on canola by the Pest Management Regulatory Agency before using the product in Canada. In some cases, a pesticide is registered in Canada without a maximum residue limit (MRL) established in our major export markets. This means that canola treated with these pesticides may not be in compliance with the requirements of the importing country.

The following pesticides are not recommended for use on canola:

  • FUNGICIDE 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.
  • HERBICIDE 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.
  • HERBICIDE Accord, Facet, Clever, 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 2016 that has been treated with quinclorac. Until 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.

Storage Icon3. ALWAYS FOLLOW THE CANOLA STORAGE RECOMMENDATIONS
  • 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.
Blackleg Icon4. GROW BLACKLEG RESISTANT VARIETIES AND USE PRACTICES THAT REDUCE INFECTION

All canola varieties are rated for resistance to blackleg. Plant only R (resistant) or MR (moderately resistant) rated canola varieties.

Blackleg Management Practices
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.

  • Scout canola fields regularly for blackleg symptoms and prevalence. Having this information will allow you to 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 in the field, a minimum break of two to three years is recommended.
  • Plant certified treated seed. This is the first step in keeping your field clean.
  • Rotate varieties to bring a mix of blackleg resistance genes to the field over time, which can prevent or delay the breakdown of resistance.
  • 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.
Deregistered Icon 5. DO NOT GROW THESE 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 - up to $400,000.

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.
