The application belongs to the technical field of pesticide acaricidal technology, and discloses an acaricide and application thereof. The acaricide comprises active ingredient A and active ingredient B. The active ingredient A is a compound of formula I. The active ingredient B is any one of flujaepram or bromopropylate. The mass ratio of the active ingredient A to the active ingredient B is 1:45-42:1. The acaricide has obvious synergistic effect on various harmful mites, can effectively control the harm of the harmful mites, and reduces the use amount of the pesticide and slows down the development of the resistance of the harmful mites.

The present invention discloses a safe and clean preparation method for a bromofen technical, belonging to the field of chemical synthesis technology. 4,4′-dibromodiphenylacetic acid isopropyl ester is first dissolved in a DMF solvent, the flow rate is controlled, and the product is simultaneously pumped into a microreactor with hydrogen peroxide to obtain the bromofen technical. The preparation method of the present invention uses hydrogen peroxide as an oxidant to react with the liquid-liquid flow stream, which is a single-phase reaction and can greatly reduce the amount of oxidant used. The present invention also adopts a continuous feeding and discharging method in the microreactor to reduce the contact time between the excess oxidant and the product bromofen, thereby controlling the generation of peroxide and avoiding the occurrence of safety accidents.
