During curing or storage, leaves may be rotted or discolored by these bacteria. The symptoms first appear as blackening of the veins or midribs. Large areas or whole leaves may decay. This soft rot bacterium is present in the soil and on green leaves. Barn rot begins when leaves are harvested wet and not properly dried before curing. This bacterium also causes hollow stalk in the field under wet conditions.
