"Saskatchewan's Ministry of Agriculture surveyed over 200 fields in 2025 for several diseases that impact canola and have now published surveillance maps ahead of the growing season. As part of the General Canola Disease Survey a total of 201 fields were sampled in 2025 for verticillium stripe and clubroot. In addition to the Ministry of Agriculture's verticillium stripe monitoring program, the Saskatchewan Oilseeds Development Commission (Sask Oilseeds) continued to include verticillium stripe in its free disease testing program for canola producers."
"This program confirmed the occurrence of the disease in 20 RMs. These findings were also used to generate the 2025 map, below. Verticillium stripe was confirmed by DNA-based testing (PCR) in a total of 66 fields, representing 33 per cent prevalence among the fields assessed in Saskatchewan. In total, 73 RMs were confirmed to have verticillium stripe during the 2025 season, as illustrated in the 2025 Verticillium Stripe in Saskatchewan Canola Crops map."
"The 2025 Clubroot Distribution Map shows rural municipalities (RMs) in Saskatchewan where clubroot has been detected since its first confirmation in 2008 (below). The map remains unchanged from 2024, as no new cases were confirmed in 2025 through the Saskatchewan Clubroot Monitoring Program. In 2025, no new fields with visible clubroot symptoms and no new fields with clubroot pathogen DNA were confirmed."
Surveillance in 2025 sampled a total of 235 fields across 152 rural municipalities through a 201-field General Canola Disease Survey and a 34-field voluntary on‑farm soil testing program. Verticillium stripe was confirmed by PCR in 66 fields, representing 33 percent prevalence among assessed fields, and was detected in 73 RMs, with most cases on the province’s east side and additional detections in west-central and southwest Saskatchewan as far west as the RM of Oakdale. The Clubroot Distribution Map remained unchanged from 2024; no new fields with visible clubroot symptoms or clubroot pathogen DNA were confirmed in 2025.
