Problems solved by technology

For example, Chinese patent CN 201410090210.4 is a compound pesticide synergist and its application in pesticide preparations. The castor oil polyoxyethylene ether, alkylphenol polyoxyethylene ether, sorbitan fat mentioned in the composition of the invention Ester is still compounded with chemical substances. Although the synergistic effect is increased to a certain extent and the dosage is reduced, the chemical substances are easy to accumulate on green plants, thereby causing pollution to the ecological environment. In urban park scenic spots, it may even cause harm to tourists. Therefore, the existing compounding technology needs to be further improved, and compound pesticides that are more friendly to humans and the environment should be used.

[0004] To sum up, for the above problems of urban greening pests and the use of chemical acaricides, people have realized that it has become a trend to develop a safe and non-residue plant Chinese herbal compound acaricide, and there will be a broad market. Market development prospects, but due to various reasons such as benefits and control effects, compound acaricides containing plant Chinese herbal medicines are not ideal in the process of promotion and use
