Problems solved by technology

The Chinese patent application with application number 201110314061.1 discloses a solid microemulsion containing pyrethroid insecticides. In its preparation method, non-polar solvents are still used to dissolve the active ingredients of solid pesticides. The method is only applicable to pyrethroids. Insecticides, not a one-size-fits-all approach

Abstract

The invention discloses solid microemulsion. The solid microemulsion comprises the following components in percentage by weight: 0.2%-20% of pesticide active ingredient, 30%-70% of solid non-ionic emulsifying agent, 0-10% of solid cation emulsifying agent, 0-40% of water-soluble carrier, and the balance of fertilizer carrier. The solid microemulsion is free of any chemical solvent, good in stability of pesticide active ingredient, small in pollution to the environment, broad in application range, capable of bringing multiple effects of the pesticide effect and the fertilizer effect into play while preventing crop insect pests and weeds, and therefore, the solid microemulsion is an efficient labor-saving novel dosage form.

Description

technical field [0001] The invention relates to a solid microemulsion with insecticidal, bactericidal and herbicidal biological activities and a preparation method thereof, belonging to the field of pesticides. Background technique [0002] At present, the common dosage forms of pesticide preparations include emulsifiable concentrate, water emulsion, microemulsion, wettable powder, water dispersible granule and so on. The emulsifiable concentrate uses a large amount of chemical solvents, which has high residues and pollutes the environment. The emulsifiable concentrate products are flammable and explosive during storage and transportation, and there are safety risks. Water emulsions and microemulsions also contain a small amount of chemical solvents, which do not fundamentally solve the pollution of chemical solvents, and there are certain limitations in the long-term stability of active ingredients in water in these formulations, so quality stability problems are prone to o...
