|White blister is a fungal-like disease of brassicas that began devastating Victorian broccoli crops during the summer of 2001-02.
It has since spread rapidly across Australia, despite the implementation of interstate trade barriers.
The consequences for industry are year-round fungicide applications to control the unsightly white blisters and swellings on the leaves and heads.
With support of AUSVEG, HAL and the Victorian Government, researched at DPI Victoria has developed management strategies for white blister on seed, seedlings and in the field.
This project details the outcomes of a 3 year study on management strategies for white blister (rust) on brassicas which:
The major outcomes of this project are improved management strategies for white blister control in
These strategies are growing more tolerant cultivars, avoidance of evening irrigation and
This project developed a molecular test to distinguish
It was established that inoculum from the common weed Shepherd’s purse and
However, as inoculum from shepherd�s purse does cause disease on broccoli
Growers should use the seed test to ensure they start with ‘clean seed’, grow less susceptible
This approach will maximize the production of broccoli that meets the high aesthetic standards in the
