While you’re in the field checking canola to see if it’s ready to be cut, or perhaps already swathing or harvesting it, it’s also a good time to assess the toll disease took on your crop. Sclerotinia, blackleg and clubroot can all cause premature ripening, as disease symptoms become more obvious at the end of the season,… Read More

Hot conditions can have an impact on both yield and quality in canola, making timing more important when swathing or straight-cutting the crop. Much of Western Canada has experienced a mid-August heat wave, with fields maturing rapidly in the heat. For canola, this means the time to cut can sneak up quickly. In this Canola… Read More
Canola fields with spotty emergence and heat-blasted pods have farmers in parts of the prairies grappling with the thought that their crops might not be worth combining. But that doesn’t mean it’s time to till it under. “There are some other uses for canola that we normally wouldn’t consider,” says Keith Gabert, agronomy specialist with the Canola Council… Read More
As little as 2% green seed in a canola sample can cause the loss of a No. 1 grade in Canada, traditionally equating to roughly $10-15/tonne. Immature canola seed naturally contains chlorophyll, a green pigment essential for photosynthesis. As canola seeds mature, enzymes remove the chlorophyll, a process thought to improve seed longevity. The enzymes responsible, however, are… Read More
With the canola crop maturing later than normal in parts of Western Canada, there’s some concern about frost hurting the crop. Temperatures dipped close to freezing in some parts of the Prairies earlier this week, with reports of light frost in northern Alberta. In this Canola School, Warren Ward, agronomy specialist for Eastern Saskatchewan with… Read More
With canola swathing underway across Western Canada, now is the time for growers to assess the toll that diseases have taken on the crop. The “what to look for” list at this time includes the main suspects: blackleg, sclerotinia and clubroot. In this episode of the Canola School, Keith Gabert of the Canola Council of… Read More
Hot summer days and over-wintered canola — a disaster waiting to happen, or a non-issue? Turns out, as of last fall, there was little if any research to reference on the safety of storing canola well into the hot summer months. Canola growers will be pleased to learn that that’s no longer the case, as… Read More
Oilseeds are riskier to store. That’s just a fact, and canola is no different. In fact, the higher the oil content — a plus for the canola crop — is also a liability when it comes to safe storage. In the last Canola School, Keith Gabert, agronomy specialist with the Canola Council of Canada, went… Read More
Post-harvest spray applications are an effective way to deal with hard-to-control perennial and winter annual weeds like Canadian thistle, foxtail barley and dandelion. But, whether you’re dealing with frost, labour shortages or incredibly dry conditions, spraying in the fall can be a challenge. A dry fall can not only limit the active growth of weeds,… Read More
Canola that goes in the bin dry but hot is still at risk for spoilage. The same can be said for grain with high weed seed, insect parts or just dockage in general. While it seems obvious to some, reports of full bin losses happen every year — losses that could be avoided simply by… Read More
The canola crop is ripening at an incredible pace — should you wait and straight cut or try and swath ASAP? How fast is too fast to combine canola, in either scenario? These are questions that come up every year, but the trade-off between swathing and straight-cutting are especially important this year as the canola… Read More
In a perfect world, all canola fields would have uniform maturity and one large, heavily podded main stem, making swath timing decisions easy peasy. The reality, of course, is that emergence problems, hail events and heat stress can all cause maturity variability, excessive branching or yield-heavy secondary stems that need to be included in the… Read More
Abiotic — or “nonliving” — stresses can cause significant yield loss in canola. And, unfortunately, symptoms like sterile and distorted pods, flower blast and pale petals are not unique to one stressor, making misdiagnosis very common. For example, extreme heat, nutrient deficiency and herbicide injury can all result in very similar damage in canola plants…. Read More
The decision to swath or straight-cut is one you will ultimately have to make on your own. It may depend on a multitude of factors: the number of people available to help, the plant stand, how many acres you have to harvest etc. etc. But, what if you gave it a shot? Would you commit… Read More
With a mostly beautiful harvest under our belts and the cold weather setting in, it’s easy to forget that some canola went into the bin on very, very hot days. While 8% moisture is considered the “safe” moisture level for long-term canola storage, the safety of that bin is in jeopardy if the temperature was… Read More
