The Grains Research and Development Corporation has funded the National Canola Pathology Project, which revised its blackleg ratings following confirmation of reduced resistance in some Group A canola cultivars.
Farmers planning to use seed retained from last year’s crops are advised to see if that seed is from a cultivar classified as being more susceptible to blackleg, Marcroft Grains Pathology principal Dr Steve Marcroft said.
“Screenings have confirmed that the resistance status of some Group A cultivars has changed and growers must be aware of these new ratings before they sow this year’s canola crops,” Dr Marcroft said.
