The loss is often 20 per cent, and occa- sionally a total loss is reported. Upon the pods the disease appears as dark- colored spots, usually sunken, varying in size from 1-10 mm., or more if sev- eral spots coalesce. The border of the spot is often tinged with red, the center rust-colored. Old pod-spots overlying seeds within cause spots upon these seeds. The pod-spots are much more noticeable and unsightly upon light-colored than upon green beans. Similar spots are found upon the stems and leaves. They are especially noticeable upon young stems still blanched and upon the seed leaves.
