Unless blackleg can be controlled there is little future for rapeseed as a major commercial crop in W.A.
Until 1972, oilseed rape showed great promise as an alternative cash crop for Western Australian farmers, especially in the Great Southern and south coastal areas.
However, like most other cruciferous crops, rape is prone to attack from diseases and insect pests. Most of these can be controlled, but the fungus disease blackleg (Leptosphaeria maculans) emerged as a major threat to the industry.
Clearly, unless the disease can be controlled, there is little future for rapeseed as a major commercial crop in Western Australia.
