Tasmanian canola growers have been urged to check the latest blackleg disease ratings for canola cultivars ahead of sowing this season.
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.
