Problems solved by technology

[0004] At present, the commonly used 0.5% lime sulfur mixture is sprayed for prevention and control or 2000 times of Fenzain emulsion is used for killing. 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
