When strange patterns of damage in canola fields line up perfectly with the sprayer boom width or follow typical drift patterns, phone calls and finger pointing begin. Explanations can be simple: The wrong product was added to the tank, or the right product was applied but on the wrong field. But situations are often much more complicated — and made…

Heat at flowering and hail at late flowering and podding can be highly damaging to yield. Lost pods are yield that cannot be recovered, and hail that knocks back a crop at this stage often doesn’t give the crop enough time to compensate and produce a good crop before fall frost. Growers often look for rescue treatments to revive the…

The risk of sclerotinia stem rot infection is still present on later crops that have not reached full flower, especially given the rain and high humidity in some regions this week. Highly variable crops may also be at “full flower” or their “most yellow” — other terms for 50% flower — for longer than typically expected, which also extends the…

Sulphur and nitrogen deficiencies are showing up in some canola crops. The crop may not have received enough fertilizer to begin with, especially if this year’s rates did not compensate for high yields and high removal last year. Excess moisture may have added to nutrient losses. Flowering is not an ideal time to top dress, and applications any time after…

Diagnosis: Ugly. A lot of canola crops are looking pretty sad, with small plants, low counts and a wide range of stages. This makes for difficult management decisions, including when to spray for sclerotinia stem rot — or whether to spray at all. Late fungicide. The application window for fungicide to manage sclerotinia stem rot closes at 50% flower (or…

How well can you identify the causes of canola root damage? We have six photos for you, including the one above…

This zoomed in section of the Alberta bertha armyworm map shows the only location across the Prairies, to date, showing a "severe" level of adult moths. That location is at Lacombe…

Growers in many regions are reporting canola fields that just don’t look as good as usual. Many are thin stands with weak plants and variable stages of maturity. Here are 10 most likely reasons…

Foot rot and brown girdling root rot (BGRR) seem to be more common this year. If you see dying plants or plants with lower leaves dying off while other plants remain green, this may indicate abnormal root function. Dig them up and check the roots for rots and girdling…
