Bean Pod Mottle

This disease caused by the bean pod mottle virus (BPMV), often occurs in combination with soybean mosaic virus. The virus is transmitted mainly by the feeding of certain insects, particularly the bean leaf beetle. The virus is not seed transmitted.

In the field, diseased plants show a mild yellow mottling on young actively growing leaves. As these leaves approach maturity the mottling becomes masked. Plants infected with both soybean mosaic and pod mottle are stunted, have distorted foliage, misshapen fruit, and necrotic tissue. Seed from plants infected with pod mottle are smaller than normal.
