White mould, also known as sclerotinia, caused the wilted patches in Paul’s soybeans.
It’s fairly easy to make a visual diagnosis of this disease because of the white, cotton-like growth that develops on the affected plant’s stem. Stems and pods infected with white mould can also appear pale brown and water-soaked. Frequently, small black bodies (sclerotia) can be seen on the stems of diseased plants. Plants are generally killed in patches late in the growing season.
