It’s certainly not a disease you want to find in your fields, but if you do, there are good reasons to talk about it — specifically, report it — says Michael Harding, research scientist with Alberta Agriculture and Forestry. “If it’s the first time clubroot’s been found in the field, by reporting it, you can get… Read More

According to speakers at last week’s Canola Galla in Penhold, AB, a single gram of soil (roughly the size of a Smartie) can contain hundreds — if not thousands or even millions — of resting clubroot spores. And, those resting spores can survive up to 20 years in the soil, spreading by catching rides on wind, water,… Read More
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
The canola industry has been among the most vocal advocates of Canada being part of a possible Trans-Pacific Partnership trade deal. So what’s in it for canola growers? According to industry estimates, canola exports could grow by $780 million if tariffs on Canadian canola oil and meal were eliminated across the TPP region. For this… 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
Boron’s complete role in plant health is not entirely understood, but the nutrient does play a key role in cell elongation, hormone response and membrane function. Boron is a micronutrient necessary for optimal yield and growth, but needed in only very small quantities. In Western Canada, trials surrounding boron have shown inconsistencies in yield response,… Read More
It should come as no surprise to insect geeks that the ash-grey insect above with a rather distracting snout is a weevil. More specifically, it’s a cabbage seedpod weevil (Ceutorhynchus obstrictus), an insect pest that has been infecting canola crops (and other Brassicaceae species) in Alberta since the mid-1990s, and it has since moved across the southern portion… Read More
As a diverse set of volunteers in the agriculture industry, it’s hard to assign a worth to the work beneficial insects accomplish, but their absence can speak volumes, if you’re listening. To showcase that, Jim Broatch, pest management specialist with Alberta Agriculture and Rural Development, talks root maggots in this Canola School, and how an insecticide application… Read More
Frost has taken a toll on the canola crop in Western Canada over the last few weeks. In some cases, where temperatures dropped well below -2 degrees for an extended period, the decision to reseed is easy. However, the replanting decision is more complicated in most instances. As part of this Canola School episode, Anastasia Kubinec of… Read More
