AI Technical Summary

Technical Problem

The dosage forms of existing acetic herbicides are mainly wettable powders. During use, solid particles are not easily absorbed by weeds, resulting in a large loss of effective pesticide ingredients, which is easy to cause pollution to the environment. At the same time, dust will be generated during processing and use, which will harm producers and the environment.

Method used

Complexing agent and synergistic complexing agent are used to wrap alkynium ester into hydrophilic droplets, and combined with moisturizer and surfactant to make liquid herbicides without the need to add organic solvents, which improves water solubility and reduces environmental pollution.

Benefits of technology

The green and environmentally friendly effect of alkynacetate herbicide is achieved, reducing the use of organic solvents, reducing the damage to the environment, and improving the use efficiency of herbicides.
