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 spraying rigs to spread disease within and between paddocks.
Varieties Note the relative resistance of the current lupin varieties.
In higher risk situations do not grow Kiev Mutant, Wodjil, Myallie or Tallerack. Tanjil and Wonga are the most resistant followed by Kalya. Plan for 2000 clean seed now Set up a clean seed multiplication area on your farm at low risk of infection or organise a reliable source off-farm if you are in a high risk area. Management packages for anthracnose control in narrow-leafed lupins have been well promoted and industry awareness is high. Two new narrow-leafed varieties, Wonga and Tanjil are showed excellent resistance to anthracnose in 1998 trials although they are not immune.
