The 2019 Canola Discovery Forum hosted by the Manitoba Canola Growers Association in Winnipeg, MB, brought together researchers and industry from throughout the canola value chain to discuss the role Integrated Pest Management (IPM) plays in canola production, and how the Canola Council of Canada (CCC) is working to reach the goal of 52 bu/acre average canola production by 2025.

Good old-fashioned weed control

The forum opened with three updates on weed, insect and disease management from CCC agronomy specialists. The importance of weed control isn’t a new discussion, and the topic doesn’t often capture headlines the way “exciting” pests like clubroot or blackleg have in recent years.

But while the topic may not be flashy, CCC agronomy specialist Ian Epp focused his update on emphasizing the importance of proactive, solid weed control and using practices to steward the effective weed control options currently available for canola.

“We have really good weed control options in canola, but weed control is still something to think about,” says Epp. “We need to protect that really good weed control that we have. But, we can’t take weed control for granted, a key example is herbicide resistance.”

Epp’s Top 5 Weed Management Practices:

  1. Scout
  2. Spray early
  3. Manage volunteers
  4. Good agronomy = good weed management
  5. Try something new!

Epp says it is important for growers to do something different in their weed management each year. This can be a hard sell, he says, if everything is going well. Growers often want to stick with tried and true strategies; however, he says making proactive changes can go a long way to reducing the potential impacts of herbicide resistance.

“If we don’t change, the weeds will be changing,” he says. “The numbers of herbicide resistant cases we see only go up. Weed control might not be too hard in canola right now, but I think the writing has been on the wall for a while now that it’s about to get a lot more challenging.

“Getting growers engaged and earlier and looking at alternative methods before we see a huge, Australia-like problem will be really key going forward.”

Non-herbicide management options

Epp also touched on some of these alternative methods, including the Harrington Seed Destructor and WEEDit. Both of these machines have been in use in Australia for years and are starting to pop up across the Canadian prairies as growers look for options to battle herbicide resistance.
