Annual Clubroot Inspection Completed


September 25, 2018 marked the completion of the annual clubroot inspection done by Lac Ste. Anne County. We inspect all canola fields for visible symptoms of clubroot on canola plants, as per Policy 408 – Control of Clubroot Disease.


Thank you to all producers who participated in the annual inspections! Lac Ste. Anne County is endlessly impressed with our producers’ ability to prevent the spread of this soil-borne crop disease. By this point, anyone with a confirmed field should have received the news already, either contacted by the County or by the landowner of the property. If you wish to confirm whether your field was found positive, there is a clubroot map available for viewing at the County office. Over the last eight years we have seen a distinct high-low cycle of finding clubroot within the County, as shown in the graph below.

This year followed the pattern; only five clubroot cases were found compared to last year’s 18. We believe this has to do with the common two-year rotation that many producers follow. Please take note of this cycle in your crop rotation decisions for 2019, especially if you are in a high-risk area.

We will be sending our 2018 samples to be tested at the Crop Diversification Centre North to understand what pathotypes are present in our County. However, this testing takes several months over the winter, as they must identify the type of canola, grow it in lab, and do a resistance test by inoculating the plants with several pathotypes. We did not get an answer from our 2017 samples until April of this year. Unfortunately, that doesn’t help producers make cropping choices for 2019, but as soon as we have an answer, we will provide it publicly.

Lac Ste. Anne County will be hosting another Clubroot Information Session on November 20, 2018 at the County office. We will cover topics including clubroot biology and lifecycle, genetic resistance breakdown explained, and management practices. More information will be provided soon.
