Reduce reservoirs of infection Control infected blue lupins on fence-lines and roadways. To be effective these need to be sprayed out early in the seedling stage before the disease has a chance to multiply and spread. Control volunteer lupins in cereal and canola crops in paddocks that will be sown to lupins the following season. Machinery hygiene Avoid contaminating clean seed with infected material during harvest and grading. Be aware of the potential for ground spraying rigs to spread disease within and between paddocks.
Varieties Note the relative resistance of the current lupin varieties.
In higher risk situations avoid the susceptible Myallie and Wodjil varieties. Kiev Mutant is extremely susceptible. Wonga followed by Kalya are the most resistant narrow-leafed varieties.
