Anthracnose on stems.

Anthracnose on stems.

Occurs in cool moist conditions and spreads rapidly in high humidity and warm temperatures (25-30°C). Disease spreads rapidly towards the end of the season with a large number of lesions developing.

This disease is not present in Australia.

Reported in a number of countries, but only economically important in Canada.

Sow disease free seed.

Submit samples to your local Department of Agriculture or Primary Industries for confirmation.

Irregular shaped, light brown sunken lesions develop on the base of the stem, progressing up the plant to the leaves and pods. Only a few circular lesions develop on leaves and pods. The centre of lesions contain small, black micro-sclerotia survival bodies.

Affected plants lodge.

Could be confused with ascochyta blight.
