Abstract

The invention discloses a scoparone missible oil acaricide and a preparation method thereof, and belongs to the technical field of pesticides. The acaricide comprises scoparone, a solvent, an emulsifier and a filling agent, the mass percents of the solvent, the emulsifier and the filling agent is (35-60): (8-12): (40-50), and the mass percentage of the scoparone and the emulsifier is 1: 2. The preparation method comprises the following steps: (1) taking raw materials for later use; (2) adding scoparone into a solvent, and uniformly stirring to obtain a mixed solution; and (3) adding the emulsifier into the mixed solution, stirring uniformly, adding the filling agent, and mixing and stirring uniformly. The prepared acaricide has good dispersibility in water and uniform emulsification, belongs to an environment-friendly natural acaricide, has little harm to human bodies and environments, can be decomposed, and is stable in hot storage and cold storage and easy to store.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a basartemisinic acid emulsifiable acaricide and a preparation method thereof. Background technique [0002] At present, there are many kinds of pesticide formulations in my country, such as oil, emulsifiable concentrate, powder, wettable powder, suspension concentrate, granule, water formulation, etc. Among them, the emulsifiable concentrate formulation is that the original pesticide is dissolved in organic solvents such as toluene and xylene in proportion. Add a certain amount of pesticide-specific emulsifiers such as calcium alkylphenyl iodate and non-ionic emulsifiers, and then prepare a transparent homogeneous liquid, which has the characteristics of convenient application, high drug efficacy, relatively stable properties, and easy dispersion in water. , which has a large output and a wide range of applications, is a major formulation of pesticides. In addition, when using...
