Aside from bean, its host range includes beets, cabbage, lettuce, peas, pepper, tomatoes, and many others. Warm, relatively dry soil conditions favor disease development. Management Do not grow beans or other susceptible crops continually in the same location. Continuous cropping of susceptible plants will eventually lead to a buildup of these fungi in the soil. Avoid planting beans in fields known to be heavily infested with bean root-rot fungi.
Plant beans only on well-drained soils or try to improve drainage.
Subsoiling to a depth below the plowed layer will reduce soil compaction, and improve drainage. Deep plowing of the previous years' crop residues will reduce bean root rot. Avoid planting seeds too close together-follow instructions on the seed container. Do not overfertilize, especially with nitrogen. In hydroponics, there are several ways to combat damping-off including the following.
