Abstract

The present invention discloses an insecticidal composition containing thiamethoxam and emamectin benzoate and applications thereof. In the composition, thiamethoxam and emamectin benzoate serve as active ingredients and a foliar fertilizer serves as a synergistic aid. The insecticidal composition provided by the present invention has an obvious synergistic effect and effectively exerts advantages of the three, and the obtained product has excellent quality and good efficacy and is applicable to fruit trees, vegetables, flowers, cereals and other crops in preventing and controlling various insects. The composition main works on efficacy and the spectrum of control and so on. According to the composition provided by the present invention, the applied dose of the insecticide and the number of times of application are greatly reduced; the economic cost is reduced; the amounts of insecticide residuals on the agricultural products and in the environment are reduced; insecticide resistance is prolonged; and the service life of the insecticide is prolonged, thereby achieving great significance in economy, environmental protection and ecology.

Description

technical field [0001] The invention relates to a preparation method and application of a pesticide composition, in particular to an insecticide composition containing thiamethoxam and emamectin emamectin, a preparation method and application thereof. The insecticide composition is suitable for controlling various pests in crops such as fruit trees, vegetables, cotton and cereals. Background technique [0002] Thiamethoxam, English name: thiamethoxam, chemical name: 3-(2-chloro-1,3-thiazol-5-ylmethyl)-5-methyl-1,3,5-oxadiazin-4-yl Forked(nitro)amines. Thiamethoxam pure product is white crystalline powder, melting point 139.1°C, vapor pressure: 6.6×10-9Pa (20°C), solubility (25°C, g / L): water 4.1, organic solvent (25°C, g / L) : Acetone 48, ethyl acetate 7.0, methanol 13, dichloromethane 110, hexane>1mg / L, octanol 620mg / L, toluene 680mg / L. Thiamethoxam is a neonicotinoid high-efficiency and low-toxicity insecticide, which has stomach toxicity, contact killing and systemic...
