Herbicides are one tool for managing cleavers in canola, but there are many other "small hammers" in the toolbox as well. Seeding rates, row spacing, control timing, and crop rotation all need to be considered, explains Ian Epp, agronomy specialist with the Canola Council of Canada, in this episode of Canola School. "We can add... Read More

Granular phosphorus fertilizer recovered from liquid hog manure could be a viable alternative to traditional 11-52 monoammonium phosphate (MAP) fertilizer for growing wheat and canola, according to research done at the University of Manitoba. Struvite "looks like a fantastic fertilizer," says Don Flaten, U of M soil scientist and one of the authors of a... Read More

To some growers, it's an old idea; to others, it's completely new. The concept of peola — intercropping peas and canola — has been around in Western Canada for decades, but with new varieties and weed control options, the practice seems to be gaining momentum again. In 2009, the Westman Agricultural Diversification Organization found an... Read More

Glyphosate-resistant kochia has started showing up in more of Western Canada, and as with other cases of resistance, it's becoming evident you can't rely on a single tool for too long. Minimizing resistant weed populations requires an integrated or diverse approach. The crop itself must help make survival difficult for potentially resistant weed seedlings, explains... Read More

The message to canola growers from the Canola Council of Canada and grain companies over the last few months has been straightforward: Don't apply quinclorac herbicide to canola this year because it could jeopardize exports. Farmers will have to sign a declaration saying their canola has not been treated with quinclorac for it to be... Read More

Parts per million versus pounds per acre. Olsen versus Bray. Nitrogen versus nitrate... Some of the numbers and technical terms on the paper or email you get from the soil test lab are relevant for understanding nutrient availability for your crop and others don't actually mean much for growing crops Western Canada. So which numbers... Read More

There's a new name for the canola disease that first showed up in Canada in a research plot in Manitoba in 2014. Caused by the fungus Verticillium longisporum, the disease was referred to by its common name in Europe: verticillium wilt. The problem is it doesn't appear to cause wilting in canola. "The symptoms that... Read More

Editor's note: The Canadian verticillium stakeholders committee has decided to call the disease caused by Verticillium longisporum "verticillium stripe" instead of "verticillium wilt." This story has been updated to reflect the new terminology. The canola industry is in the early stages of understanding what it's up against with a new fungal disease. Verticillium stripe (previously... Read More

The Chinese government has agreed to postpone tighter dockage standards on Canadian canola. In February, China indicated a new standard allowing no more than 1 percent foreign material would be implemented on April 1. As Reuters first reported on Tuesday morning, China's import policy changes have now been postponed until September 1, 2016. The Chinese... Read More

As soybeans are introduced and grown more frequently in rotations that already include canola in Western Canada, growers may find their soil bank accounts for phosphorus and potassium running low. Both canola and soybeans are heavy users/removers of P and K, explains Laryssa Grenkow of Manitoba Pulse and Soybean Growers in this Canola School episode,... Read More
