Canola most sensitive to potential trade disruption

A long list of pesticide residues and other issues have the potential to derail canola exports

Few Canadian crops rely on exports as much as canola so making sure they don’t contain pesticides customers prohibit is critical to protecting markets, the Canola Council of Canada (CCC) says.

“Canada exports 90 per cent of the canola we produce, and shipments containing even the smallest amount of unacceptable residues or deregistered varieties can be rejected, causing millions of dollars in losses and placing future business at risk,” the CCC says on its Keep it Clean website.

“Don’t spoil the bunch. Produce export-quality canola and protect Canada’s reputation as a quality supplier by following these guidelines closely.”

Here’s some of what the CCC recommends:

Use acceptable pesticides only

Only apply pesticides registered for use on canola in Canada. Talk with your grain buyer before you spray to ensure the pesticides you’re using are acceptable to your customers.

Do not use:

  • Accord, Facet, Clever (Quinclorac) and Masterline Quinclorac.
    Western Grains Elevator Association-member companies and the Canadian Oilseed Processors Association will not accept delivery of canola grown and harvested in 2016 that has been treated with quinclorac.
  • 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.
  • 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.

Consult your grain buyer before using:

  • Quash
    Some grain companies have indicated they will not accept canola treated with metconazole (the active ingredient in Quash) in 2016. Consult your grain buyer.

Use pesticides correctly

  • Follow the label. Stick to the pre-harvest interval (PHI). 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.
  • Control blackleg. Blackleg is initiated by spores from infected canola residue or stubble.
    Plant only canola varieties rated R (resistant) or MR (moderately resistant). Rotate varieties to bring a mix of blackleg resistance. Plant certified treated seed.
    Scout fields regularly to help determine the effectiveness of your blackleg management plan.
    Maintain a break between canola crops so crop residue can decompose. If blackleg is established, a minimum break of two to three years is recommended.
    Consider applying a fungicide if the disease shows up early.
    Control volunteer canola and other brassica weeds (stinkweed, shepherd’s purse, wild mustard, flixweed) to prevent blackleg buildup during non-canola years.
  • Store canola properly
    Ensure storage bins are free of treated seed (which contains pesticides) and animal protein like blood and bone meal.
    Clean bins thoroughly prior to storing canola.
    Never use malathion to treat canola bins. Keep canola cool and dry to avoid spoilage and insect issues.

Do not grow deregistered varieties

  • Signing the mandatory Declaration of Eligibility affidavit at the elevator is 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 deregistered varieties or any seed produced from them:
    — 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.
