[0001] The invention relates to an acaricide in the technical field of pesticides and its preparation, in particular to a compound botanical acaricide and a preparation method thereof. Background technique

[0002] In recent years, due to the irrational use of chemical pesticides and the inherent shortcomings of the pesticides themselves, a series of public hazards have arisen in the use of pesticides, such as environmental pollution, human and animal poisoning, killing natural enemies, destroying ecological balance, "3R" (Residue , Resistance, Resurgence) and other serious problems, these adverse effects have aroused widespread concern. On the other hand, the success rate of synthetic pesticide development is low, the cycle is long, and the cost is astonishing. Due to the above reasons, when the pesticide industry in various countries in the world is looking for new bio-rational pesticides, they turn their attention to bio-rational pesticides that are highl...
