Crop rotation and seed decisions are improved when growers and agronomists have a good handle on the disease situation. Blackleg levels were higher than expected in some areas this year, and clubroot continues to spread. Knowledge of the incidence and severity of these two diseases provides an important head start in keeping them under control… -
The first step in canola volunteer management is to do nothing. Leaving seeds undisturbed so they germinate in the fall or get eaten by birds and insects is a good way to reduce the volunteer seedbank. Canola seeds that remain on the soil surface when the snow flies will deteriorate over the winter… -
Fall is a good time to control perennial and winter annual weeds. The message this week includes two reminders: 1. Wait for post-harvest regrowth. 2. Know the best timing for the weeds present… -
Weed management includes a keen eye for the unusual. “Unusual” can be suspicious patches of common weeds (herbicide resistance?) and presence of new unknown weeds. Jimsonweed is, for many, an usual and unknown weed. (Shown above.) It was reported in several Alberta canola fields a couple weeks ago, and has now been confirmed in fields in 11 Alberta municipalities… -
After a drought-stressed summer in many areas of the Prairies, canola plants may have a lingering hormone response that can cause seed sprouting (above) in the pods and regrowth of cut plants… -
Ideally, growers will want to put canola on aeration as soon as it comes of the field. Cooling hot grain within the first 24 hours is important for safe long-term storage. Removing moisture that sweats from all canola — but especially tough canola (10-12% moisture) — is also important. Conditioning achieves both of these steps. Here are a few handy… -

If you want to use soil test results to see whether this year’s crop had enough nutrients, sampling now would be the better option. To plan for next year, soil samples taken closer to freeze up are a more accurate estimate of levels next spring…
