Pathogenicity

Brien et al. (1955) showed that this fungus was associated with lesions on pods and leaves. It sometimes occurs on stems, where it may cause a collar rot. Curtis (1923) showed it to be associated with a collar rot in lupins. It may cause considerable damage in pea crops. As the disease is seed borne, seed should be saved only from disease-free crops and should be dusted with a fungicide prior to sowing.
