Problems solved by technology

Since the particles of the wettable powder are relatively coarse, larger particles are attached to the surface of the weeds during use, and the weeds are not easy to absorb, and the relative amount of use is relatively large, resulting in a large loss of active ingredients of the pesticide, which is easy to damage the environment. long-term pollution

Embodiment 1

[0020] A kind of clodinafop-propargyl microemulsion and preparation method thereof, it first prepares 2 kilograms of clodinafop-propargyl former medicines, 5 kilograms of dimethylformamide, 2 kilograms of n-butanols, 4 kilograms of nonionic surfactants, anionic surfactants as raw material. Then add all the dimethylformamide and n-butanol into the stirring reaction kettle and mix evenly, then add the clodinafop-propargyl original drug and mix and stir for about 1 hour, and the rotation speed is controlled at 50 rpm. Then add nonionic surfactant and anionic surfactant and continue to stir evenly, finally add water to make up to 20 kg, and continue to stir for 1 hour to make it a uniform transparent solution product.

Embodiment 2

[0022] A kind of clodinafop-propargyl microemulsion and preparation method thereof, it prepares 1 kilogram of clodinafop-propargyl former medicine earlier, 3 kilograms of dimethylformamide, 3 kilograms of isobutanols, 3 kilograms of nonionic surfactants, anionic surfactants as raw material. Then add all the dimethylformamide and n-butanol into the stirring reaction kettle and mix evenly, then add the clodinafop-propargyl original drug and mix and stir for about 1 hour, and the speed is controlled at 100 rpm. Then add nonionic surfactant and anionic surfactant and continue to stir evenly, finally add water to make up to 20 kg, and continue to stir for 2 hours to make it a uniform transparent solution product.

Abstract

The invention relates to a clodinafop-propargyl microemulsion and a preparation method thereof; the microemulsion comprises the following components in percentage by weight: 1 to 50 percent of clodinafop-propargyl, 1 to 20 percent of solvent, 1 to 20 percent of cosolvent, 5 to 30 percent of emulsifier and 50 to 90 percent of water. First, the solvent, the cosolvent and the clodinafop-propargyl are uniformly stirred and mixed by weight percent at the rotating speed of 50 to 200r/min, and then are added with the emulsifier according to the ratio requirement to be uniformly stirred again, and finally are added with water to be continuously stirred for 1 to 2h, and the uniform and transparent solution product is prepared. The clodinafop-propargyl microemulsion of the invention is mainly used to cure tail alopecurus, wild oat, false oat, brachiaria, digitaria, barnyard grass, cricket grass, Italian ryegrass, chenopodium, general bluegrass, gold setaria, setaria, johnson grass, halepense and the like. The microemulsion of the invention not only can effectively improve the use efficiency of medicine, but also can reduce the pollution for the environment.

Description

technical field [0001] The invention relates to a pesticide herbicide microemulsion, in particular to a herbicide clodinafop-propargyl microemulsion and a preparation method thereof. Background technique [0002] The chemical name of the compound clodinafop-propargyl is 2-propynyl-(R)-2-4[4-(5-chloro-3-fluoro-2-pyridyloxy)phenoxy]propionate. [0003] Its structural formula is: [0004] [0005] The English common name of clodinafop-propargyl is Clodinafop-propargyl, and the trade names include top herbicide and Maiji. CAS number: 105512-06-9 (105511-96-4) (105511-96-4). [0006] Clodinafop-propargyl is developed and developed by ciba-Geigy Company. It belongs to aryloxyphenoxypropionic acid herbicides. It can effectively inhibit the biosynthesis of esters and become an acetyl cosensitizer A hydroxylase inhibitor. This product degrades quickly in soil Part of the free acid phenyl and pyridine enters the soil. Clodinafop-propargyl can effectively control sagegrass, wild...
