Abstract

The invention discloses a high efficient mite-killing composition, which comprises an active component A and an active component B, wherein the active component A is selected from spiromesifen, the active component B is any one compound selected from the following components: tebufenpyrad, hexythiazox, fenazaquin and halfenprox, and the weight ratio of the active component A to the active component B is 1:70 to 70:1. The high efficient mite-killing composition can control a plurality of harmful mites, has a prominent synergetic effect, is capable of reducing the using amount of pesticide, reduces the residual pesticide amount on crops, and relieves 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] Molecular formula of Spiromesifen: C 23 h 30 o 4 . The mechanism of action of spiromethin is to affect the development of whiteflies and mites, interfere with the biosynthesis of their liposomes, especially have good activity on the larval stage, and at the same time, it can also produce ovariectal closure, reducing the incidence of mites and whitefly adults. reproductive capacity, greatly reducing the number of eggs laid. [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 s...
