Spinosad soluble agent and preparation method thereof

Abstract

The invention discloses a spinosad soluble agent which comprises the following components based on the mass fraction: 2.5%-28% of spinosad bulk drug, 10%-12% of surfactant, 21%-25% of adjuvant and 37%-66% of water. The invention further discloses a preparation method of the spinosad soluble agent, comprising the following steps: proportionally weighing the spinosad bulk drug, the surfactant, the adjuvant and water; placing the materials into a reaction bottle; and under the water bath condition at the temperature of 20-100 DEG C, fully stirring the materials into a transparent liquid to finally obtain the spinosad soluble agent. In the invention, the botanical pesticide spinosad can be dissolved in a solvent to obtain the spinosad soluble agent by adopting a simple, safe and environmental-friendly process, which lays a foundation for application and popularization of the spinosad soluble agent in agricultural production.

Description

technical field [0001] The invention relates to a chemical pesticide, in particular to a soluble formulation containing the botanical pesticide spinosad; the invention also relates to a preparation method of the spinosad soluble formulation. Background technique [0002] At present, the development of green pesticides, especially biopesticides, has attracted more and more attention. Among them, spinosad, a botanical pesticide, has attracted special attention because of its high activity, broad insecticidal spectrum, and environmental friendliness. However, since spinosad is insoluble in water and has very low solubility in organic solvents, the current spinosad pesticides mainly use suspension concentrates, emulsifiable concentrates, anticide baits, water emulsions and other dosage forms, because they cannot be prepared into solutions. , so it is more difficult to promote and use, and it has not been widely accepted by people. Therefore, the research and preparation of the...
