Problems solved by technology

[0007] Another difficulty with the use of insecticides is that the repeated and exclusive use of a single insecticidal compound in many cases leads to rapid selection of pests that have developed natural or adapted resistance to the active ingredient.

Abstract

The invention relates to an insecticidal composition, which contains active compounds SYP-9625 and spirobudiclofen in a weight ratio of 50:1-1:50. The invention also relates to use of the insecticidalcomposition in prevention or control of psyllidae, chrysomelidae, cicadellidae and whitefly pests. The invention also relates to a method for prevention or control of psyllidae, chrysomelidae, cicadellidae and whitefly pests. The insecticidal composition provided by the invention can be applied to seeds, target useful plants or plant growth soil, or soil suitable for plant growth.

Description

technical field [0001] The present invention relates to an insecticidal composition, which contains active compounds ethafenapyr and spirodiclofen. The present invention also relates to the use of the pesticidal composition for preventing or controlling the pests of the family Psyllids, Beetles, Leafhoppers, Whiteflies and their larvae and eggs. Background technique [0002] Chemical control is an important means of preventing and controlling pests in agriculture. However, when the chemical cannot guarantee complete coverage of the leaves, only finding insecticidal compositions that can penetrate into the plant and then transfer to the appropriate site can be effective against pests that live in a hidden way of life or live in a dormant state in a safe location. [0003] Ethoxafen (SYP-9625) is a pyrazolyl acrylonitrile compound jointly developed by Sinochem Corporation and Shenyang Chemical Research Institute Co., Ltd., which has been disclosed in CN101875633A. Ethoxyfen ...
