Insect and disease surveys across the Prairies have moved to a permission-based system to access fields for monitoring. Canola Watch uses this information to improve canola pest management. How to grant permission…

Scientific research in Western Canada shows lower yields for canola in short rotations. Blackleg (shown above), clubroot and many other factors can cause this yield loss…

Justine Cornelsen, agronomy specialist with the Canola Council of Canada, provided an overview of verticillium stripe disease for a Saskatchewan Ministry of Agriculture webinar. View the webinar recording. The Canola Encyclopedia……

Soil sample the fall after canola harvest or the spring immediately following. This gives galls time to break down and release spores. If sampling this fall, target fields that are going into canola next year…not fields that were in canola this year…

The fungal pathogen Verticillium longisporum causes stem cross-section discolouration that can look somewhat like blackleg and bleaching of the stem that can look somewhat like sclerotinia stem rot. But these diseases are all quite different in terms of yield risk and management, so it’s important to be able to tell them apart… -
Canola grower organizations in Saskatchewan, Manitoba and Alberta encourage farmers and agronomists to do more field testing… -
Around 60 per cent seed colour change (swath timing) is the best time to scout for blackleg as the basal cankers, which cause significant yield loss, are easy to see. Check fields – even if growing resistant (R) rated hybrids. An R rating is not immunity and does not tell much about if it will be effective against the races… -
This article runs through a series of questions and scenarios, a bit like "choose your own adventure", to help farmers and agronomists come up with an appropriate management plan for each situation… -
You have been actively scouting and found clubroot early. The disease is confined to “patches” or small areas in your field, typically around field entrances, drainage paths or low spots in the field. Here’s what to do with them…
