Abstract

The invention discloses a high-efficiency miticidal composition containing an active ingredient (A) and an active ingredient (B). The active ingredient (A) is acequinocyl. The active ingredient (B) is one of tebufenpyrad, hexythiazox, fenazaquin and halfenprox. The weight ratio of the active ingredient (A) to the active ingredient (B) is 1:70 to 70:1. The high-efficiency miticidal composition has the effects of preventing various pest mites, obviously synergizing, reducing the dosage of pesticides, decreasing the residual amount of pesticides on crops and alleviating the environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency acaricidal composition on crop pest mites. technical background [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] Tebufenpyrad (Tebufenpyrad) chemical name: N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide, molecular formula: C 18 h 24 CLN 3 O. It is an amide acaricide. It has excellent effects on various mites and harmful mites of Hemiptera and Homoptera, and Dan has quick-acting and high-efficiency effects on all growth stages of mites, and has a long-...
