Trichlopyr, dicamba and glyphosate-containing complex herbicide and preparation technology thereof

Abstract

The invention discloses a trichlopyr, dicamba and glyphosate-containing complex herbicide, active ingredients include glyphosate, dicamba and trichlopyr, the weight ratio of glyphosate to dicamba to trichlopyr is 1-90:1-90:1-90, and the content of glyphosate, dicamba and trichlopyr accounts for 62% of the total weight of the complex herbicide. The complex herbicide can be made into a wet powder, a soluble powder, a water agent and a microemulsion. The complex herbicide can reduce the resistance of weeds, and has the characteristics of short seed death time and high seed death rate.

Description

technical field [0001] The invention relates to a herbicide and a preparation method thereof, in particular to a compound herbicide of clopyroxyacetic acid, dicamba and glyphosate and a preparation process thereof, belonging to the field of pesticide preparations. Background technique [0002] Pesticides used to eliminate or control the growth of weeds are called herbicides, and herbicides can be classified according to the mode of action, application site, and compound source. According to the mode of action, it can be divided into selective herbicides and total herbicides. According to the movement of herbicides in plants, they can be divided into contact herbicides, systemic conduction herbicides and systemic conduction and contact herbicides. According to the chemical structure, it is divided into inorganic compound herbicides and organic compound herbicides. According to the method of use, it is divided into stem and leaf treatment agent, soil treatment agent and stem...
