Abstract

The invention relates to the technical field of insecticides, and particularly discloses an insecticide containing spinetoram and sulfoxaflor, a preparation method and application thereof. The insecticide containing spinetoram and sulfoxaflor is mainly prepared from the following raw materials in parts by weight: 3-25 parts of an active component A, 2-10 parts of an active component B, 1.2-3 parts of tetrabutyl ammonium hydroxide, 5-12 parts of an auxiliary agent and 50-80 parts of a solvent, wherein the active component A is composed of spinetoram and sulfoxaflor according to a mass ratio of (6-10): (1.5-4), and the active component B is composed of sodium polyphosphate, a surfactant and dimethyl sulfoxide according to a mass ratio of (7-12): (1-3). The insecticide disclosed by the invention can be used for preventing and treating pests of lepidoptera, thysanoptera, diptera and the like, and has the advantages of high infiltration capacity and good contact killing effect.

Description

technical field [0001] The application relates to the technical field of pesticides, more specifically, it relates to a pesticide containing spinosyn and sulfoxaflor and its preparation method and application. Background technique [0002] In recent years, the widespread application of pesticides in agricultural production has played a very good control effect on agricultural pests, reducing the frequency of pest outbreaks and greatly increasing the output of agricultural products. However, due to the use of pesticides, pests have developed a certain resistance, and the efficacy of the pesticides has decreased year by year. Therefore, technicians have developed insecticides that mix different types of pesticides, and have achieved better insecticidal effects. [0003] Spinosad is a macrolide biosourced pesticide product, which can act on nicotinic acetylcholine receptors and γ-aminobutyric acid receptors in insects, and has a good effect on Lepidoptera and Diptera pests. pr...
