example 1

[0024] 10% azoxystrobin · chlorothalonil microemulsion. The weight percentages of each component are: azoxystrobin 5%, chlorothalonil 5%, methanol 10%, phenethylphenol polyoxyethylene ether 4%, octylphenol polyoxyethylene ether sodium phosphate 7%, Ethylene glycol 4%, deionized water make up 100%. Preparation method: According to the above ratio, put the weighed azoxystrobin, chlorothalonil, methanol, phenethylphenol polyoxyethylene ether, octylphenol polyoxyethylene ether sodium phosphate into the homogeneous mixer and fully Stir evenly, then slowly add the water phase dissolved in ethylene glycol, vigorously mix and homogenize, and obtain 10% 10% azoxystrobin·chlorothalonil microemulsion.

Abstract

The invention relates to an agricultural fungicide, in particular relating to a method for preparing an azoxystrobin and chlorothalonil microemulsion. The microemulsion comprises the following components by weight percent: 5-20% of azoxystrobin, 5-15% of chlorothalonil, 5-25% of latent solvent, 5-25% of surface active agent, 2-8% of freeze-proof agent, 0.5-4% of penetrating agent and the balance of water, wherein the total weight percent of the components is 100%. The water is used as the matrix of the microemulsion, the production cost is low, the microemulsion is easily packaged, and the microemulsion is safely produced, stored, transported and used. The microemulsion can be used for preventing and treating various fungus diseases of crops, is small in environmental pollution, and is beneficial to improving the quality of ecological environment.

Description

technical field [0001] The invention relates to an agricultural fungicide, in particular to a preparation method of azoxystrobin and chlorothalonil microemulsion. technical background [0002] Pesticide microemulsion is an environmentally friendly green pesticide preparation newly developed in the 1980s. It uses water as a medium to homogenize effective active components that are insoluble in water through a homogenization process by means of dispersion and emulsification. Dispersed in water to form a thermodynamically stable system of oil-in-water type. After the dispersed phase in the emulsion is homogenized, the droplet diameter is less than or equal to 0.1 microns, so the product has a transparent appearance, good physical and chemical stability, and high control efficiency. [0003] The microemulsion uses water as the main solvent, which not only saves a lot of organic solvents, but also greatly reduces the pollution to the environment after the application of the medi...
