SaskCanola, in collaboration with the Saskatchewan Ministry of Agriculture, will continue to offer free disease testing for blackleg and clubroot to farmers, with the addition of testing for verticillium stripe new this year. Verticillium stripe was first reported in Canada in 2014, and there is still much to learn about this disease. It presents symptoms… Read More

Verticillium stripe — a disease first discovered in Western Canada in 2014 — appears to be taking advantage of the stress to canola plants caused by an old, familiar disease pathogen. While research to understand Verticillium longisporum in the Prairies is still in its early stages, there’s a hypothesis that its prevalence in a canola… Read More
When scouting for blackleg, many imagine clipping stems near swathing or harvest time. But did you know that infection actually occurs at the very beginning of the growing season? If you’re in a high risk situation, such as a tight rotation, growing the same variety, or have background resistance in the field, the disease can… Read More
A new seed treatment from Syngenta specifically targets foliar infection of blackleg in canola with a new mode of action, adding another tool in the blackleg management toolbox. “[Saltro] really has nice fit in an integrated management system with crop rotations and, of course, the genetics play a key role,” says Ted Labun, technical lead… Read More
As temperatures warm, fields across the west are starting to see flea beetle emergence, and cotyledon defoliation. And that has producers wondering about when to take action. “There’s been some discussion about different threshold levels,” says Errin Willenborg, agronomist with Federated Co-op Ltd. The discussion stems from confusion around two listed thresholds — the 25… Read More
Like other relationships, export markets take time, energy, and diplomacy to develop and maintain. Agriculture trade can be impacted by politics that have very little to do with farming and food, and big-picture friction in the short-term could threaten years of hard work. Just as good news rolls in on reduced tariffs for Canadian agriculture… Read More
Verticillium stripe, also known as verticillium wilt, is a relatively new-to-Canada canola disease. First identified on a research farm in Manitoba in 2014, the Canadian Food Inspection Agency (CFIA) conducted a nation-wide survey to determine the extensiveness of the pathogen in 2015, and found it to be in multiple locations. In this episode of Canola… Read More
Every once in a while a group with a real passion for something get a chance to get together and talk about what they care about. If you get to be in room with with them, you can’t help but feel the energy and, most likely, learn something. The Western Forum on Pest Management (WFPM)… Read More
You may notice some new information on canola seed bags this year — a label that lists what type of blackleg resistance the variety contains. We’ll spare you all the quirky names and numbers for the actual genetic resistance, but Dilantha Fernando, with the University of Manitoba, says farmers can use the alphabetical designation of… Read More
There’s this thing about nature — it adapts. Many canola growers are getting a real taste of this in recent years by a slow but steady resurgence of blackleg showing up and stealing yield. For those who think, “hey, we have genetic resistance, didn’t we deal with this already?” read and listen on. Record canola… Read More
