Clodinafop-propargyl microemulsion and preparation method thereof

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...

AI Technical Summary

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

At the same time, the airflow pulverization used in the processing of wettable powder will inevitably generate dust in the actual production process, which not only endangers the producers, but also pollutes the environment due to the drift of dust.

The wettable powder also causes secondary pollution to the environment due to the generation of dust during use
