Problems solved by technology

[0005] At present, chemical pesticides and fungicides are usually used to prevent and control the diseases of Artemisia annua, and the problem of environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious
At the same time, the use of chemical pesticides and fungicides can cause plant pathogenic bacteria to develop drug resistance and drug resistance, which increases the difficulty of control and even causes the failure of control.
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
