Such as China’s famous Mingguang mung bean origin in Jiashan County, Anhui Province for the spot leaf spot in the area of ​​70 acres of mung bean farming in 1979 due to leaf spot damage received only 40 pounds of seeds. In order to seek the effective control of leaf spot disease, we carried out comparative experiments on prevention and control of several pesticides in Jiashan County, Anhui Province from July to October of 1984, which provided a basis for the prevention and treatment of large-scale diseases.
