Problems solved by technology

[0004] (1) Short storage stability time: the normal storage time of pesticides is 2-3 years, while the normal storage time of water emulsion is about 1 year;
[0005] (2) Stratification is easy to occur: it will break the emulsion due to temperature, physical and chemical changes of the original drug and additives, ultraviolet rays, time, water quality, etc., that is, the separation of water and solvent to form stratification;
[0006] (3) Precipitation is prone to occur: due to the decomposition of auxiliary agents and the original drug, the original drug will fall out of the preparation, form rice grains or crystal-like substances and sink to the bottom, greatly reducing the efficacy and effectiveness of the product. content of ingredients;
[0007] (4) It is difficult to solve the problem of pesticide synergy: since water is the main solvent, the formation of water emulsion is a principle of dynamic stability. , is extremely unstable in this dosage form. Therefore, the surface swelling force of the normal dosage form of water-emulsion is similar to that of water. Poor adhesion and penetration are the biggest problems of water-emulsion, and it is difficult to improve the efficacy of the product.

Abstract

The invention discloses a water emulsion pesticide, comprising the following compositions in percentage by weight: 8.5-40% of technical material, 10-35% of xylene, 0.8-7.2% of cyclohexanone, 2.1-6% of agricultural emulsion 602#, 0.6-5.3% of agricultural emulsion 404#, 1.3-3.2% of N-alkylbenzisothiazolone, and the rest amount of water; and the technical material comprises one or two of prochloraz, emamectin benzoate, coumoxystrobin, diethofencarb pyrimethanil amines, iprodione, triazophos, spiroxamine, kresoxim, pyridaben, propiconazole and tetraconazole. The water emulsion pesticide and the production technology thereof have the advantages that the application range is wide, the dosage form is stable, the synergy is obvious, and the production technology is simple.

Description

technical field [0001] The invention relates to a water-emulsion insecticide, in particular to a water-emulsion insecticide and a production process thereof, belonging to the field of water-emulsion insecticides. Background technique [0002] With the strengthening of people's awareness of the environment, it is required to reduce the environmental hazards caused by the use of pesticides. In order to meet this social requirement, in the development of pesticide products, while focusing on the development of new varieties of pesticides with low toxicity and high efficiency, higher requirements are put forward for pesticide preparations, and the development of pesticide preparations is required to be solidified and water-based. [0003] The international code name of water emulsion dosage form is Ew, which was once called concentrated emulsion (Concentrate Emulsion). It is a preparation made by mixing liquid or mixed with a solvent to disperse the liquid pesticide original dru...
