Abstract

The invention discloses a microemulsion pesticide. The microemulsion pesticide consists of the following ingredients in percentage by weight: 2.2-10% of active pharmaceutical ingredients, 2.5-20% of cyclohexanone, 2-10% of polyoxyethylene nonyl phenyl ether, 0.5-5% of agricultural emulsion No. 500, 2-10% of agricultural emulsion No. 602 and the balance of water, wherein the active pharmaceutical ingredients comprise one or two of beta-cypermethrin, iambda-cyhalothrin, cyfluthrin, methomyl, carbosulfan, pyriproxyfen, fluacrypyrim, diafenthiuron, hexaflumuron, phoxim, abamectin and acetamiprid. The microemulsion pesticide has the advantages of wide application scope, stable formulation and simple formula, and is convenient to operate.

Description

technical field [0001] The invention relates to an insecticide, in particular to a microemulsion insecticide and a preparation process thereof, belonging to the field of microemulsion insecticides. Background technique [0002] For a long time, with the widespread use of chemical pesticides, people have paid more and more attention to how to reduce environmental pollution and poisoning to humans and animals. Reducing toxicity and improving drug efficacy are the development trend of pesticides. At present, my country is relatively backward in the research and development of pesticide dosage forms. Taking emulsifiable concentrate and wettable powder as examples, their consumption accounts for 70-80% of the total preparation amount; and the dosage form is relatively single, and the ratio of the original drug to the preparation is 1: 6. In developed countries, the ratio is about 1:30, which is far from it. Obviously, this is far from adapting to the current development of agricu...
