Acaricidal composition and preparation thereof, and application of acaricidal composition and preparation

Abstract

The invention belongs to the technical field of pesticides, and especially relates to an acaricidal composition and a preparation thereof, and an application of the acaricidal composition and the preparation. The effective components of the acaricidal composition comprise an active component A and an active component B; the effective component A is Acynonapyr, and the active component B is one ormore of pyridaben, etoxazole, spirodiclofen and fenpropathrin; a mass ratio of the active component A to the active component B is 80: 1 to 1:80, preferably 40:1 to 1:40, and more preferably 20:1 to 1:20; and the content sum of the active component A and the active component in the acaricidal composition is 5-80 wt%. The acaricidal composition or the preparation thereof has the advantages of effect enhancement, dosage reduction, prolongation of the lasting period, and delaying of the development of the pesticide resistance.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and in particular relates to an acaricidal composition and its preparation, and the application of the acaricidal composition and the preparation. Background technique

[0002] Acynonapyr is a miticide newly developed by Japan Soda Company. It can be used to control harmful mites in fruits, vegetables and tea trees, and has no cross resistance with other miticides, which has important promotion significance. The CAS chemical name of Acynonapyr is (3-endo)-3-[2-propoxy-4-(trifluoromethyl)phenoxy]-9-[[5-(trifluoromethyl)-2-pyridine Base]oxyl]-9-azabicyclo[3.3.1]nonane (CAS: No.1332838-17-1), its structural formula is as follows:

[0003]

[0004] At present, pyridaben, etoxazole, spirodiclofen, and fenpropathrin are all commonly used insecticides / acaricides, and have good control effects on harmful mites in agriculture.
