Abstract

The invention discloses a spinosad soluble concentrate which comprises the components in percentage by mass: 1% to 5% of a spinosad active compound, 70% to 88% of a solvent, 10% to 20% of a penetrating agent and 1% to 5% of an auxiliary agent. The invention also discloses a preparation method of the spinosad soluble concentrate, wherein the preparation method comprises the steps: heating an ethanol solvent to 30 DEG C-35 DEG C, adding the spinosad active compound while stirring, heating to 40 DEG C-50 DEG C, adding N-N-dimethylformamide and methanol while stirring, cooling to 40 DEG C or less, adding the penetrating agent, stirring until the solution becomes a homogeneous transparent liquid, and thus obtaining the spinosad soluble concentrate. The problem that spinosad is difficult to dissolve in water and organic solvents is solved, the spinosad soluble concentrate is prepared, the use range of spinosad is expanded, and the use method of spinosad is simplified.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, in particular to a spinosad soluble agent and a preparation method thereof. Background technique [0002] At present, the development of green pesticides, especially biopesticides, has attracted more and more attention. Among them, the biopesticide spinosad has attracted special attention because of its high activity, wide insecticidal spectrum and environmental friendliness. Spinosad, as a highly efficient and safe biopesticide, can be widely used in the prevention and control of domestic agricultural and forestry pests, storage pests, sanitary pests and livestock parasites. Accelerating the development of spinosad biopesticides will undoubtedly There is a huge market and broad prospects in the country. However, since spinosad is insoluble in water and has low solubility in organic solvents, the current spinosad pesticides mainly use suspension concentrates, emulsifiable concentrates, an...
