Embodiment 1

[0023] 10% propargite microemulsion. 10g of propargite, 6g of N-methylpyrrolidone, 5g of 600#, 5g of polyethylene glycol, 5g of piperonyl butoxide, and 69g of water. Dissolve the crude oil of alkyne in the solvent, put in the emulsifier, then put in the synergist and the stabilizer, stir well, and then put it into the homogenizer equipped with dispersion medium water, mix vigorously and homogenize to get the alkyne Mite microemulsion products.

Embodiment 2

[0025] 25% propargite microemulsion. 25g of propargite, 10g of N-methylpyrrolidone, 8g of 600#, 6g of polyethylene glycol, 5g of piperonyl butoxide, and 54g of water. Dissolve the crude oil of alkyne in the solvent, put in the emulsifier, then put in the synergist and the stabilizer, stir well, and then put it into the homogenizer equipped with dispersion medium water, mix vigorously and homogenize to get the alkyne Mite microemulsion products.

Embodiment 3

[0027] 40% propargite microemulsion. 40g of propargite, 18g of N-methylpyrrolidone, 8g of 600#, 6g of polyethylene glycol, 5g of piperonyl butoxide, and 23g of water. Dissolve the crude oil of alkyne in the solvent, put in the emulsifier, then put in the synergist and the stabilizer, stir well, and then put it into the homogenizer equipped with dispersion medium water, mix vigorously and homogenize to get the alkyne Mite microemulsion products.

Abstract

The invention discloses a preparation method of a propargite microemulsion. By selecting and studying a plurality of solvents, emulsifying agents and preparation technologies, the invention replaces a large number of organic solvents with water, thus reducing the environment pollution from agricultural chemicals. The propargite microemulsion prepared by using an appropriate surface active agent and an addition agent through ultramicro-thinning process has high chemical and physical stability and strong emulsifying dispersivity, and is a non-polluted acaricide with high efficient, broad spectrum and low toxicity. The acaricide is characterized in that the propargite microemulsion contains 1 to 45 percent of propargite, 5 to 30 percent of solvent, 5 to 10 percent of stabilizing agent, 5 to 10 percent of synergistic agent, 5 to 30 percent of emulsifying agent, and 20 to 70 percent of water. The propargite crude oil is dissolved in the solvent into which emulsifying agent, synergistic agent and stabilizing agent are put and stirred evenly, and then the solvent is put in a viscolizer which is filled with dispersive medium water for strong mixing and homogenization, thus obtaining the propargite microemulsion product.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a method for preparing a propargite microemulsion. The invention uses water to replace a large amount of organic solvents through the screening and research of various solvents, emulsifiers and preparation processes, thereby reducing the pollution of pesticides to the environment. technical background [0002] Propargite, the common name of propargite, propargate, chemical name: 2-(4-tert-butylphenoxy)-cyclohexylprop-2-ynyl sulfite, is a low-toxicity broad-spectrum organic Sulfur acaricide, with contact and stomach toxicity, no systemic and penetration. It is effective against adult mites and nymphs, and the duration of effect can reach 30-35 days. Propargite can be used to prevent and control harmful mites in various crops such as cotton, vegetables, apples, citrus, tea, flowers, etc. It can also effectively control mites that are resistant to organophosphorus and organochlorine pest...
