Problems solved by technology

Triazotin is a broad-spectrum acaricide with strong contact effect, which can kill nymphs, adults and summer eggs, but is ineffective against winter eggs
After research by the inventors, it was found that acequinone could produce a good synergistic effect after being compounded with tetrafenazine, triazotin, fenbutatin, flufenazine, and bromofen. The relevant reports on compounding of oxazine, triazotin, fenbutatin, flufenazine and bromofen have not yet been made public

Abstract

The invention discloses an acaricidal composition containing acarquinone, the acaricidal composition containing active ingredient A and active ingredient B, wherein the active ingredient A is selected from acarquinone, and the active ingredient B is selected from any of the following compounds : tetrafenazine, triazotin, fenbutatin, flufenazine, bromofen, and the weight ratio of active ingredient A to active ingredient B is 1:80~80:1. The composition of the present invention has a synergistic effect on various harmful mites that endanger agricultural production, reduces the dosage of pesticides, reduces the residual amount of pesticides on crops, reduces environmental pollution, is safe for humans and animals, and has good environmental compatibility. It is not easy for pest mites to develop resistance.

Description

[0001] This application is a divisional application. The original application is a patent application of Shaanxi Meibang Pesticide Co., Ltd. "An acaricidal composition containing acequinone". The application number of the original application is: 201210215651.3, and the original application date is 2012.06.27. technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of an acaricidal composition containing acequinone on crop pests. Background technique [0003] Acequinocyl chemical name: 2-(acetoxy) 3-dodecyl-1,4-naphthoquinone, molecular formula: C 24 h 32 o 4 . Acarquinone is a naphthoquinone derivative, mainly a contact acaricide, and has ingestion toxicity. It is hydrolyzed into 2-dodecyl-3-hydroxy-1,4-naphthoquinone in the mites, and binds to the Qo site on the electron transfer channel in the mitochondria, thereby inhibiting electron transfer. [0004] Clofentezine chemical name: 3,6-bis(2-chlorophenyl)-1,2,...
