Didymella pinodes (Berk. & A. Bloxam) Petr. 1924
The fungus is wide-spread and causes ascochyta blight, a serious disease of peas. It also infects some other legumes. Initial symptoms are small purple spots on the undersides of leaves. They enlarge and become well-defined, brown- black lesions, sometimes blighting the whole leaf. Stems, flowers and pods are also affected. The infections result in stunting or plant death, in severe cases. Yield losses can reach 50% under cool and wet conditions.
Management options include crop rotation, the use of resistant cultivars and fungicides (e.g. as seed treatment). In outbreak areas, it is recommended to grow peas only once every 3-4 years.
