Vigilance system key to blackleg management
Author: Associate Professor Alex Idnurm, Dr Angela Van de Wouw and Dr Steve Marcroft, 2022-04-06T09:00:00+10:00A national surveillance system keeps a watch on the blackleg threat to Australian canola production. Led by a team of researchers networking with scientists across the regions, changes in virulence of the blackleg fungal populations are monitored annually and warnings issued to growers when canola varieties with specific resistance genes threaten high disease levels.

Opportunities to expand blackleg resistance pool
Author: Dr Susie Sprague, Dr Luke Barrett, Professor Jacqui Batley, Dr Angela Van de Wouw, Dr Steve Marcroft, 2021-05-02T09:00:00+10:00New research has identified three major resistance genes for blackleg in canola, developed markers, and is working to better understand how minor gene resistance is expressed. Screening shows that one of these major genes is present in most historic and many current Australian varieties.
