    Damaged canola in bin small

    Harvest is well underway, so the big issue this week is to make sure canola is safe in storage. You don’t want to end up with a bin like the one above. All canola should be conditioned in the few days after harvest to make sure it cools down. If you have aeration fans, turn them on right away and leave them on until canola drops to at least 15°C. If you don’t have aeration, move the canola from one bin to another, or remove one third of the canola in a bin to check its temperature. See our Top 10 for more tips.

    Growers with fields already combined may be getting ready for fall weed control. Give weeds a few weeks to regrow after harvest so they have more leaf area to hit with herbicide. Perennial control tends to be best before weather gets too cold. Winter annual control tends to be better later in the fall.

    Late canola still standing will face higher frost risk with each passing day. Leave immature canola standing as long as possible, and be prepared to swath right after the first killing frost. Swathing might not be necessary after a light frost. That’s why a post-frost assessment is important.

  • Top 10 risky situations for canola storage

    Bin cables give you an easy way to check temperatures inside the core.

    The number one risk: Neglected bins. Growers are busy enough at harvest just getting the crop off, but take time to check all bins within the first two weeks after filling, and then again a couple more times until the canola is cool and winter sets in. Canola seed continues to sweat during the first 4 to 6 weeks after harvest, making this a critical period to move air through the bin and remove that moist air. It cannot always wait until after harvest. Canola can jump from 30°C to 50°C and beyond in two weeks or less.


  • Frost hits standing canola: What to do?

    This was taken 4 hours after a minus 7°C frost. Green pods are already turning white and popping open.

    Check standing canola the morning after a frost, but wait at least 4-6 hours after frost to allow the full extent of severe frost damage to become evident. The crop may look undamaged that morning but by lunch time, wilting, desiccation and pod splitting may begin. If you scout early and then not again, you may underestimate the damage and miss a chance to swath now to save some of the yield. Conversely, light to moderate frost damage may take longer to become evident, so scout again after 2 to 3 days to reassess and make a decision.


  • Fall weed control: Tips

    Check which weeds are present in fields planned for canola in 2013. Fall is a good time to clean up winter annuals, such as cleavers (shown), that could be harder to control next spring.

    Growers planning post harvest weed control to clean up fields planned for canola in 2014, take these steps for improved control and to avoid herbicide carryover damage in canola.


  • Fall weed control: Product options

    Canola is sensitive to carryover from many herbicides. Here’s the list of products that could be used in the fall on fields planned for canola next spring, but read the notes carefully. You’ll find useful pointers to help in your product choice and herbicide timing.


  • Dry-down herbicide for straight combining

    Straight cut Brackenreed

    Some growers who straight combine canola that is not a glyphosate tolerant variety will apply glyphosate to even out the crop for easier harvest. When using glyphosate in this fashion, make sure a majority of the field is mature. Growers using Reglone on canola to be straight combined take note: Reglone can increase both pod shatter and pod drop if harvesting is delayed, so be prepared to combine as soon as green seed and seed moisture have reached suitable levels.


  • Harvest safety: Tips to save a life

    Harvest is a farmer’s busiest time of the year and unfortunately one of the most dangerous. Fatigue and stress often lead to shortcuts and unsafe practices during this time. It is essential to take breaks, slow down, follow safe practices, and ensure everyone on the farm is trained to do the task at hand.
