The action threshold for flea beetles in canola crops in Canada is an average leaf area loss of 25 per cent or more. How do you make that assessment?… -

Seed treatments are generally pretty good, but Krista Anderson from Bayer, Mark Belmonte from University of Manitoba and Autumn Barnes from the CCC explain the factors that can increase risks…

from the perspectives of herbicide uptake, efficacy and label requirements, night spraying is OK as long as weeds are not under any stress and are growing actively going into the evening… -
Canola fields may benefit from a top-dress application of nitrogen or sulphur (or both) if logistics and weather prevented the full recommended application of fertilizer at or before seeding, and if improved weather conditions (rainfall, for example) have increased the yield potential of the crop…

Any canola in storage should be checked – just to make sure it's safe. Reports of heating bins are trickling in this week… -
When growers have canola stands of fewer than four plants per square foot — due to low seeding rates, poor emergence, insects*, crusting, frost, wind, etc. — they grapple with the question whether to reseed…
