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 combination containing acequinocyl. The acaricidal combination contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from the acequinocyl, the active ingredient B is selected from any one of the following compounds: clofentezine, azacyclotin, fenbutatin oxide, flutenzine and bromopropylate, and the weight ratio of the active ingredient A to the active ingredient B is 1:80-80:1. The combination has a synergistic effect on various pest mites damaging the agricultural production, the dosage of pesticides is reduced, the residual quantity of the pesticides on crops is reduced, and the environmental pollution is alleviated. The combination is safe for people and livestock and has good environmental compatibility, and the pest mites do not easily have drug resistance.

Description

technical field [0001] 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 [0002] 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. [0003] Clofentezine chemical name: 3,6-bis(2-chlorophenyl)-1,2,4,5-tetrazine, molecular formula: C 14 h 8 C 12 N 4 . Tetrafenazine is a special-effect acaricide with long-lasting efficacy. It is effective for the eggs and nymphs of Panonychus spp. and red spider mites that occur on fruit trees, cotton, and ornamental plants, and is harmless to predatory mites and natur...
