Anthracnose of lupins in Western Australia

In August 1994 a severe anthracnose was found on Lupinus albus in plots at four sites in Western Australia. Colletotrichum gloeosporioides was isolated from lesions on collapsed stems. At one site the disease had spread to adjacent plots of L. albus, L. angustfolius, L. luteus and L. mutabilis. The primary infection was traced to seed lines of L. albus imported from Germany. In September 1994 procedures were put into place to eradicate the disease.
