Abstract

The invention relates to a spinosad suspension and a preparation method thereof. The spinosad suspension is prepared through mixing a spinosad original medicine, a wetting agent, a dispersant, a tackifier, an antifreeze agent, an antiseptic, an antifoaming agent and deionized water. The preparation method comprises the following steps: placing above raw materials in a barrel according to a prescribed ratio, crushing the raw materials by a high shearing machine to uniformly mix the raw materials, grinding the raw materials by a sand mill, carrying out quality inspection, and packaging the ground raw material mixture after an inspection result is qualified in order to obtain the spinosad suspension. The spinosad suspension adopting water as a medium has the advantages of low production cost, no organic solvents, safety and environmental protection, simplicity, feasibility, and good product effects.

Description

technical field [0001] The invention relates to an agricultural compound insecticide, in particular to a spinosad suspension and a preparation method thereof. [0002] technical background [0003] Suspending concentrate is a new dosage form of pesticide processing. It is composed of pesticide original drug, carrier, dispersant and water. It is viscous, flowable, dust-free, low-cost, and high-efficiency. It also has the advantages of wettable powder and emulsifiable concentrate, can be wetted by water, and has good suspension after diluted with water. No dust hazard, safe for operators and the environment; using water as the dispersion medium, there is no problem of flammability and phytotoxicity caused by organic solvents; compared with wettable powder, it is allowed to use different particle sizes of the original drug, so that the preparation The biological effect and physical stability are optimal. [0004] Spinosad, also known as spinosad, is a kind of macrolide pollut...
