Current and potential pest threats for canola in the Canadian Prairies

Canola/oilseed rape (Brassica napus L.) production in Canada has increased to become a foundational crop in the Canadian Prairies and an important economic driver of this region. The increase in seeded area, and by association its reduction in-crop rotation frequency, has made it easier for pests to overcome current recommended agronomic management practices. The Canola Council of Canada has been successful in involving the entire commodity value chain in promoting and strengthening the Canadian canola industry; however, because of this production increase it is critically important to understand, evaluate and mitigate the potential risks of canola yield losses to current and potential pests. This Perspective provides an overview of what are currently the most damaging insects, pathogens and weeds to canola in the Canadian Prairies, potential future threats and opportunities farmers, agronomists and researchers can take to minimize these risks.

Frequent surveillance, continued research and industry engagement are encouraged to overcome these and future pest problems.image

Automated summary

Canola/oilseed rape production has become a foundational crop and economic driver in the Canadian Prairies. However, the increased production and reduced crop rotation frequency have made it easier for pests to damage canola yield. Therefore, it is crucial to understand and evaluate the potential risks and take measures to minimize yield losses.
