Survey for anthracnose caused by Colletotrichum gloeosporioides in crop lupins (Lupinus angustifolius, L-albus) and ornamental lupins (L-polyphyllus)in New South Wales

Anthracnose caused by Colletotrichum gloeosporioides VCG-2 was identified o n ornamental lupins in home and public gardens and in nurseries in several towns within cropping areas of New South Wales in 1996. No anthracnose was detected in lupin crops in surveys in 1996 and 1997. The disease was traced to infected seed imported from Europe. Presence of this disease on ornamen tal lupins poses a risk that C. gloeosporioides could spread to commercial lupin crops. The need to prevent the growing of anthracnose-infected orname ntal lupins is discussed.
