The new National Potato Wart Response Plan is complete and will take effect for the 2025 potato crop.
Potato wart is soil-borne fungus that can reduce potato yield and quality. In 2021 and 2022, exports of potatoes were restricted from Prince Edward Island after the disease was found in some fields.
The response plan outlines protocols for when potato wart is detected in Canada (except for Newfoundland and Labrador).
New measures in the plan include requirements for users of restricted fields to implement preventative control plans and additional soil sampling and analysis requirements for restricted fields, the Canadian Food Inspection Agency (CFIA) said in a Thursday news release.
