Root rot, damping-off, and seed rots are major diseases of green beans and lima beans in some years and in some soils. These diseases are caused by a complex of soil-borne fungi; they are not seed-borne. These diseases tend to be spotty in fields, and their occurrence is unpredictable.
Pythium root rot is a persistent problem in areas that are poorly drained or over-irrigated. The disease can also occur in well-drained areas following extended periods of rainfall. Pythium root rot can occur at any time of the year as long as the soil remains saturated for several days or weeks.
