Clubroot resistance
Clubroot is a constantly evolving disease in canola. As such, management practices need to evolve alongside the disease to minimize its impact today, as well as in the future. Sustainability of the US canola production industry guides our position on how to best manage clubroot and how we recommend deploying clubroot-resistant genetics. With all of this in mind, growers should implement an integrated pest management (IPM) strategy that includes:
- Canola rotation of a minimum of once every three years
- Taking sanitation steps to limit the movement of infected soil
- Controlling volunteer canola and other brassica weeds that can act as hosts for the disease
- Utilizing patch management to limit the movement of clubroot on your farm
- Scouting to identify the presence of the disease
- Clubroot-resistant genetics are only effective as a sustainable practice as part of an IPM strategy and should not be relied upon alone
Since their launch, InVigor canola hybrids with clubroot resistance have been planted on over 28 million acres across Canada, where the clubroot disease pressure is much higher due to tighter rotations. That’s more than any other seed company*. For 2024, US growers can choose from six InVigor clubroot-resistant hybrids – all of which include our patented Pod Shatter Reduction technology.
New InVigor L333PC, InVigor L350PC, InVigor Choice LR354PC, InVigor L340PC, InVigor L345PC and InVigor Choice LR344PC, all contain the same first-generation clubroot resistance genetics. InVigor L343PC contains this resistance profile plus second-generation clubroot resistance to additional emerging clubroot pathotypes to help defend against the ever-evolving pathogen.
