Significant results have been achieved in the research on the control of soybean gray leaf spot by researchers from Hejiang Agricultural Science Institute of Heilongjiang Academy of Agricultural Sciences. In some countries, soybean experts believe that this research method has reached the international advanced level. Soybean gray spot disease is a worldwide disease that can significantly reduce the yield and quality of soybeans. Generally, it can reduce the yield by 12% -15%, reduce the yield by 30% and reduce the fat and protein content of soybean at the same time. In order to effectively
