The 2020 clubroot monitoring program incorporates on-farm testing, reporting of clubroot by producers and agrologists, and in-field surveillance through the general canola disease survey and a clubroot-specific survey in high-risk areas of the province. The proposed clubroot monitoring plan for 2020 is a four-pronged approach that aims to increase on-farm testing, external reporting, and formal in-field surveys. The information collected will be used to monitor the distribution of clubroot in the province and to update the Saskatchewan Clubroot Distribution Map.
- Increase External Reporting
Increasing external reports of clubroot infested fields by producers and agrologists has been a very valuable source of information.
If you would like to report a new clubroot finding, please visit How to Report a Clubroot Infected Canola Field in Saskatchewan or contact any of the following:
DNA-based testing will be used to detect low levels of the clubroot pathogen. This method of testing provides early detection of the clubroot pathogen so management strategies can be used to keep the pathogen at low levels and minimize the impact on yield.
Soil bags are no longer available effective October 30, 2020.
Sampling bags will also be provided to industry agrologists who are interested in sampling their client’s fields. The landowner/renter contact information is required before the sample will be processed. If you are an agrologist and would like to receive soil testing bags, please contact SaskCanola.
SaskCanola will cover the cost of the testing. Contact SaskCanola for more information.
Clubroot Survey in High-Risk Areas
To increase our understanding of the distribution and severity of clubroot in high-risk areas of the province, including areas near where the disease and/or pathogen are known to occur, the survey will include 300 to 400 fields. Surveyors will examine plants for clubroot galls and collect soil samples for DNA-based testing at each field. SARM plant health officers will conduct the majority of the in-field surveillance with support from Ministry staff. All surveyors will be appointed as Pest Control Officers under The Pest Control Act and will follow strict biosecurity protocols to prevent the spread of clubroot or other crop pests.
General Canola Disease Survey
The general canola disease survey is conducted annually across the province and will include 150 to 200 fields distributed across the province. This survey is completed primarily by ministry staff, SARM plant health officers and volunteers (industry agrologists). The survey includes assessing plants for the presence of all diseases, including clubroot. Soil samples will be collected to test for the presence of the clubroot pathogen when the producer/landowner has granted permission to do so.
If clubroot and/or the clubroot pathogen are confirmed, the producer will be contacted and encouraged to manage the clubroot-infested field using an integrated approach, as outlined in the Clubroot Management Plan. The specific land location will be kept confidential and will only be shared with the appropriate RM if they have a clubroot bylaw enacted.
