What are the storage risk factors this winter?
A long warm fall can put canola at elevated risk for heating and storage loss. A big risk factor this year, and any year, is high-moisture dockage. The Canadian Grain Commission compared canola seed moisture and dockage moisture for 49 samples collected through its Harvest Sample Program in 2023 and another 50 in 2024. Average seed moisture for the 2023 samples was 7.46 per cent, which is perfect for safe long-term storage of canola. The risk: Average dockage moisture was 10.8 per cent. Results from 2024 are similar. If that dockage clumps together, as it often does, this could present a storage risk. Straight-combined canola often has higher-moisture stalk and pod material. Factors that increase canola storage risk. How to check bins for spoilage.
Is it too late for soil sampling?
Not at all. Late fall is an ideal time. With results this fall, farms can determine fertilizer rates and start purchasing.
Canola needs, on average, 2.4 pounds of nitrogen, 0.9 pounds of phosphorus, 2.9 pounds of potassium and 0.9 pounds of sulphur per bushel. If the target yield is 50 bu./ac., multiply these nutrient numbers by 50 to get the crop need. Important: These are averages. Long-term soil test results paired with yield data can help refine the fertilizer recommendation. Farmers can work with agronomists to set fertilizer rates based on yield potential, fertilizer prices, crop budgets and their own risk tolerance.

How to pick the right canola cultivar for 2025?
A canola cultivar with resistance to the biggest disease risks on a farm can improve profits. This is especially true for blackleg. When planning for 2025, look back at field records for the last time canola went on that field. If blackleg caused major yield loss, it may help to (1) rotate to a different source of resistance, (2) get seed treatment to help fend off early infection or (3) wait another year before growing canola on that field. Six basics of blackleg management. Choose the right cultivar for each field.
What were the worst canola yield robbers in 2024?
The Western Forum on Pest Management brought together crop disease and insect specialists from across the Prairies last week in Regina. Many reports delivered at the forum are based on field surveys and insect traps, which rely on farmers giving permission to survey fields. Please consider giving permission in 2025. Hot topics at the forum were:
- Blackleg
- Verticillium stripe
- Cutworm
One notable to put back on your radar for 2025:
- Bertha armyworm. They weren’t bad in 2024, but a few hotspots showed up. They will cycle back at some point. Will it be 2025?

Why should I attend winter agronomy meetings?
You get to hear how the year went, and get updates on top insects and diseases. You find out what could be the big agronomy challenges next season, giving you six months to prepare. You can also network and learn from different grower groups.
The calendar is filling up with agronomy events, including provincial agronomy conferences in Manitoba, Saskatchewan and Alberta, Canola Week in Saskatoon, and general winter events. Find event updates at the provincial canola organization websites (SaskOilseeds, Alberta Canola, Manitoba Canola Growers) and in Community Connections below.
