Welcome to the latest episode of The Canola PODcast, sponsored by InVigor® hybrid canola from BASF!

In this episode, host Shaun Haney, founder of RealAgriculture, delves into the topic of clubroot with Russell Trischuk, Regional Technical Services Manager with BASF, and Leighton Blashko, a Senior Technical Service Specialist and clubroot lead for BASF Canada. They discuss the clubroot disease, its impact on canola roots and the formation of galls that restrict nutrient flow, leading to above-ground symptoms, such as stunting and wilting.

Hear Leighton Blashko give an overview of the prevalence of clubroot, emphasizing that it is now Canada-wide and not confined to specific regions. “So in all the canola growing areas, so certainly there’s pockets where it is more prevalent, but we do see it across Canada’s canola growing regions,” Blashko says.

Russell Trischuk details the available tests for clubroot, including soil and seed testing, but notes the current limitations in determining specific pathotypes. “Right now, it’s just a yes or no, which is definitely valuable, but there’s still some steps that need to be taken to get that full picture of what’s going on in every field,” he says.

Blashko emphasizes the importance of Integrated Pest Management (IPM) for clubroot and recommends keeping spore levels low and local. He advises growers to focus on diverse crop rotation, use resistant hybrids (particularly those with a ‘C’ in their name from the InVigor lineup), manage volunteer canola, and regularly scout fields, especially at entrances and areas susceptible to soil transfer.

Trischuk explains the difference between first-generation and second-generation hybrids from BASF, with the latter incorporating additional genetic components to provide resistance to a broader range of pathotypes. BASF is committed to launching hybrids with resistance to all predominant pathotypes in Western Canada; “But our strategy will always be to make sure that we’re only launching hybrids with resistance to everything. So our customers and growers don’t really have to guess which hybrids they should grow in those situations,” he says.
