What is mung bean powdery mildew?

What is mung bean powdery mildew? Please introduce the symptoms of mung bean powdery mildew: small white powdery spots scattered on the surface of the leaves. When the climate is suitable, the spots expand rapidly, and the diseased leaves are covered with powdery matter, that is, pathogenic hyphae, conidiophores and conidia. After the young pod was damaged, it was deformed and the surface was powdery. In the later stage of the development of the disease, there are small black spots in the white powder, that is, the closed capsule of the pathogen. The incidence rule of mung bean powdery mildew: the pathogen overwintered on the stump of the diseased plant with closed cysts, released ascospores in the second year, spread by wind and rain, and carried out primary infection. Conidia are produced on the disease spot, which are also transmitted by the wind and re-infected. High temperature drying is beneficial to the occurrence of diseases. The prevention and control methods of mung bean powdery mildew are as follows: one is to remove the remains of the diseased plant, and the other is to spray with 2000 times of 15% fenrucine wettable powder or 20% fenruccinin EC at the initial stage of the disease.
