How should the four common bean diseases be prevented and controlled?
1. Root drowning: Beans prefer moisture and tolerate drought but not waterlogging. Therefore, on the basis of ridge cultivation, small amounts of water should be applied to avoid water accumulation in the field, which prevents the roots from breathing and causes plant death. Control measures: Avoid flood irrigation. If there is heavy rain, drain the water promptly. After the weather clears, if conditions permit, appropriate shallow hoeing can be done to increase soil permeability and improve root vitality. 2. Phytophthora blight: It mainly damages the stems and vines, and sometimes the leaves and pods are also affected. It constricts at the base of the stem, causing the upper part to wilt and die. When humidity is high, white mycelium is produced on the diseased part.
