Four canola diseases to watch for

Four canola diseases to watch for

Is that canola crop afflicted by blackleg, root rot, both, or something else entirely? It’s a messy question farmers and agronomists encounter every year. Presenters tried to untangle those problems at CanoLAB in Vermilion this winter. Here are four diseases to watch for in canola fields this summer, and tips on diagnosing them.

Scout fields before seeding, to see if the canola residue has pseudothecia — tiny black dots that release spores.

Slowing blackleg resistance with rotation

Labelling canola seed could help farmers slow the development of genetic resistance

As blackleg resurges in Western Canada, canola growers and agronomists have been calling for seed companies to label the blackleg resistance genes on their varieties. Those labels would allow farmers to rotate resistance genes when one resistant variety breaks, the thinking goes. “We’ve been engaged with the industry over the last few years to see […] Read more


Look for cankers at swathing time. Farmers who scout regularly and don’t find blackleg might want to stick with similar canola varieties.

Managing blackleg on the farm

Clint Jurke of the Canola Council of Canada offers producers three tips

Clint Jurke, agronomy director for the Canola Council of Canada says the industry is “losing millions of dollars in terms of canola yields every year due to blackleg.” The disease is also a trade issue, and we need to improve control as much as possible, he adds. “We really want growers to look at what […] Read more

Agronomy tips... from the field

This past season brought an increase in canola disease infection levels across the Prairies. That means there’s a lot of disease inoculum sitting in your fields that will be there when you plant your next crop. Plus, we know that blackleg and clubroot are also shifting to overcome older genetics. How does this impact your […] Read more
