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 […]
In recent years, blackleg infection has affected the upper stems and branches of canola plants leading to yield loss as branches and pods on affected plants senesce prematurely causing yield loss. Steve Marcroft explains the factors researchers now believe are causing cankers on stems and branches of canola crops.

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 […]
Yellow spot causes tan – coloured lesions on the leaves that are surrounded by yellow halos.
Growers and advisers are being encouraged to send in samples of leaves with yellow spot and join researchers in the fight against yellow spot.
Results from the second year of the Stop the Spot campaign have […]

Recommended management for Ascochyta blight and Botrytis Grey Mould (BGM) in the Northern Region has been altered as a result of changes to predicted winter and spring rainfall. It is recommended that growers take a conservative approach to Ascochyta management and use an integrated disease management […]
