Blackleg fungicide tolerance survey 2015

As canola becomes more common in the rotation and the intensity of production increases so does growers reliance on fungicides to combat blackleg infection. In 2015, researchers surveyed commercial paddocks for the presence of fungicide tolerance in blackleg populations. Steve Marcroft discusses the survey, its findings and the implications for […]

Steve Marcroft explains the factors researchers now believe are causing cankers on stems and branches of canola crops. Further […]

Using cancer technology for rapid detection of fungicide resistance

Grower samples from last year’s season, along with a machine normally used for detecting mutations in cancer cells, have led to the discovery of the first signs of mutations which could lead to fungicide resistance issues in wheat powdery mildew in Australia. Digital Polymerase Chain Reaction technology picks up mutations […]
