Visible clubroot symptoms were first identified in a canola field in Alberta in 2003. It has since spread through much of the province, and by the end of 2014, it was present in 30 municipalities and into neighbouring provinces. It was also that year, that a pathotype of the disease observed the year earlier was... Read More

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... 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... 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... 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... Read More

The grain markets continued to push lower this week as favourable weather and temperatures and a strong U.S. dollar did not help any bullish players. Wheat has had nine straight sessions of going lower, dropping over 7.5 per cent in last week, while corn had its worst week in the past year, down almost seven... 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,...

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...

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... Read More
