Clubroot is a costly disease of canola, and one that requires an integrated approach to prevent its spread and the potential yield loss that comes with an infected field.
Tom Ernst, Senior Research Associate with Corteva Agriscience, explains that a collection of best management practices combine to create an overall strategy for minimizing clubroot’s impact. Everything from field selection, equipment sanitation, and on to hybrid selection work together to create the best possible outcome for canola growers.
“I can’t understate how important going in with a good rotation makes a difference in terms of the amount of inoculum in the field, the amount of spores that are available to cause infection,” Ernst says. Extending the rotation can lower spore loads, but once you know a field has clubroot it’s key to stop it from being moved to a new area.
“Anything you can do to [prevent] the spread of soil, whether it’s equipment sanitation, or even working fields… anything you can do to prevent soil movement goes a long way in preventing the spread throughout your farm or throughout the region,” Ernst says.
Genetics, too, are a key line of defence against clubroot. “Deployment of good resistance genetics is the cornerstone of our clubroot management at the moment. Choosing good, effective resistance for your area, and deploying resistance is a big part of that IPM strategy,” he says.
Growers looking to up their IPM strategy of clubroot should contact their local sales rep or the retail channel where they purchase seed and get to know the clubroot packages available in each hybrid; Corteva clubroot resistant technology is available through its two seed brands, Pioneer and Brevant seeds, both of which offer high-yielding canola hybrids with the most sources of resistance in the industry for protection against new and predominant clubroot pathotypes.
