Abstract

Disclosed is a Carbosulfan microemulsion belonging to the field of agricultural pesticide manufacture, which comprises Carbosulfan, phosphoric acid ester type anionic surface active agent, epoxides and water, characterized in that the microemulsion also comprises non-ionic surface active agent, anti-freeze agent and assisting solvent.

Description

technical field [0001] The invention belongs to the technical field of pesticide and insecticide manufacture, and in particular relates to a carbosulfan microemulsion. Background technique [0002] Pesticide microemulsion is an environmentally friendly green pesticide preparation newly developed in the 1980s. It uses water as the medium, and uses dispersion and emulsification to uniformly disperse the effective active components that are insoluble in water through the homogenization process. In water, a thermodynamically stable system of the oil-in-water type is formed. After the dispersed phase in the emulsion is homogenized, the droplet diameter is ≤0.1um, so the product has a transparent appearance, good physical and chemical stability, strong permeability to plant and insect tissue cells, and high control effect. [0003] The microemulsion uses water as the main solvent, which not only saves a lot of organic solvents, but also greatly reduces the pol...
