In 2013, an Alberta field was identified where a clubroot resistant variety showed a high incidence of clubroot infection. Subsequent testing by the University of Alberta indicated that all current forms of resistance were not functional on the disease in this soil. This failure of resistance or its breakdown was determined to be due the increasing shift to a previously…

Growers can lose up to 5 bu./ac. of canola during harvest, with many of those losses occurring as canola enters and exits the combine. Combine losses should be less than 1 bu./ac., and hopefully more like half a bushel. Here are the top 10 tips to keep combine losses to a minimum… -
The key harvest management issue with snow on standing canola concerns not so much the precipitation (although heavy snow can cause lodging) but the frost that comes with it. The common scenarios growers face with the snow on standing canola are: 1. Canola is immature when snow falls 2. Canola is ready to swath when snow falls. 3. Canola left… -
It’s complicated. We’ve said over and over to swath when the main stem reaches 60% seed colour change, and when seeds on side branches are "firm to roll" as shown in the video above. But the decision when to swath is often much more difficult — especially with the advancing calendar, disease pressure and lodging. Straight goods. Straight combining canola…

This map from Weatherfarm shows the lows for yesterday. Click here for an online and larger version of the map. Not many areas received frost yesterday, and forecast lows are not showing a widespread frost risk until at least the middle of next week… -
It pays to know how much canola your combine is throwing over. Test your harvest loss management skills…

The ideal swath timing is when 60% of seeds on the main stem are showing some colour change from green to brown. However, various factors complicate the swath timing decision, including frost and uneven crops due to hail. A few other scenarios surfaced this week, including late starts, disease and lodging (shown above)… -
Here are factors that create the ideal situation for straight combining canola…
