Abstract

The invention discloses a spinosad solution, which comprises a spinosad original drug, a penetrant, an auxiliary agent and a solvent, wherein the mass fraction of each component is: spinosad original drug 1%~ 5%, 70% to 88% of solvent, 10% to 20% of penetrant, and 1% to 5% of auxiliary agent; the invention also discloses a preparation method of the spinosad solution. Heat up to 30℃-35℃, add spinosad with stirring, heat up to 40℃~50℃, add N-N-dimethylformamide and methanol with stirring, cool down to below 40℃, add penetrant, stir until The solution becomes a homogeneous transparent liquid, and the solution of doxorubicin can be obtained. The invention solves the problem that spinosad is insoluble in water and organic solvents, prepares a spinosad soluble agent, expands the use range of spinosad, and simplifies the use method.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, in particular to a spinosad solution and a preparation method thereof. Background technique [0002] At present, the development of green pesticides, especially biological pesticides, has attracted more and more attention. Among them, the biological pesticide spinosad has attracted particular attention because of its high activity, broad insecticidal spectrum and environmental friendliness. As an efficient and safe biological insecticide, spinosad can be widely used in the prevention and control of domestic agricultural and forestry pests, storage pests, sanitary pests and livestock parasites. There is a huge market and broad prospects in the country. However, because spinosad is insoluble in water and has low solubility in organic solvents, currently spinosad pesticides are mainly used in formulations such as suspension concentrate, emulsifiable concentrate, anticide bait, and wa...
