Pyrazoxystrobin microemulsion and preparation method thereof

Abstract

The invention discloses a pyraclostrobine microemulsion and a preparation method thereof, relates to the technical field of microemulsion preparation, and aims to solve the problems that when existing azoxystrobin is used for sterilizing crops, an organic solvent needs to be mixed, the environment is polluted, some effective components in the azoxystrobin are difficult to dissolve in water, and the sterilization efficiency of azoxystrobin on crops is influenced. The pyraclostrobine microemulsion is prepared from the following raw materials in parts by weight: 30 to 50 parts of pyraclostrobine, 10 to 20 parts of a cosolvent, 5 to 10 parts of a stabilizer, 1 to 2 parts of a synergist, 5-15 parts of an anti-freezing agent, 20-50 parts of an emulsifier and 50-90 parts of purified water, the stabilizer is isopropyl phosphate, the synergist is an organosilicon polyoxyethylene ether compound, and the pyraclostrobine comprises azoxystrobin, pyrazole, a wetting agent, an adhesive and water.

Description

technical field [0001] The invention relates to the technical field of microemulsion preparation, in particular to a pyraclostrobin microemulsion and a preparation method thereof. Background technique [0002] Microemulsion is composed of liquid pesticides, surfactants, water, stabilizers, etc. It is a thermodynamically stable dispersion system over time. It is characterized by using water as the medium and contains no or little organic solvents. Safe storage and transportation, less environmental pollution, save a lot of organic solvents, azoxystrobin is an organic compound, slightly soluble in hexane, n-octanol, soluble in methanol, toluene, acetone, easily soluble in ethyl acetate, acetonitrile, Chloromethane and azoxystrobin are methoxyacrylate fungicidal pesticides with high efficiency and broad spectrum. It has good activity and can be used for stem and leaf spray, seed treatment, and soil treatment, mainly used for grain, rice, peanut, grape, potato, fruit tree, vege...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of pyraclostrobin microemulsion and preparation method thereof, to solve the problem that existing azoxystrobin proposed in the above-mentioned background technology needs to be mixed with organic solvents when carrying out bactericidal treatment to crops, which will cause environmental problems. pollution, and some active ingredients in azoxystrobin are difficult to dissolve in water, causing the problem of affecting the bactericidal efficiency of azoxystrobin on crops
