Problems solved by technology

[0004] Most of the tea gardens are located in remote mountainous areas, and tea farmers have poor food safety awareness. Furthermore, chemical pesticides are currently the most effective way to control tea pests and diseases. Therefore, tea farmers often rely solely on chemical pesticides when controlling pests and diseases. The amount is too large
According to investigations, the main varieties of chemical pesticides used in tea are methamidophos, dicofol, pyrethroids and other highly toxic and high-residue pesticides, which caused a large number of natural enemies to be killed, the ecology of tea gardens was severely damaged, and the pesticide pollution of tea was serious. large, endangering the health of consumers
[0005] Tea gardens often use copper preparations in disease prevention and sterilization. Copper preparations will damage beneficial microorganisms such as Cladomycetes, Weberia, and Polychaete, and are not conducive to inhibiting the growth of pests such as whitefly, scale insects, and mites. Population size, and thus tea disease, affects the yield and quality of tea
