Background technique [0002] At present, the fungicides used to prevent and control apple scab are usually pure chemical agents, and the problem of environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious. At the same time, when chemical pesticides and fungicides are used, various plant pathogenic bacteria will develop drug resistance and drug resistance, which will increase the difficulty of control and even cause control failure. In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective. Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants. And as the public's requirements for green an...
