Description

technical field [0001] The invention relates to the technical field of pesticide preparation, and discloses a preparation process of a pure traditional Chinese medicine herbicide. Background technique [0002] Herbicides, pesticides used to kill or control the growth of weeds are called herbicides. And weeds refer to all plants that need to be eradicated because they hinder human production, construction and life. Weeds occupy and absorb crop fertilizers or compete with crops for sunlight, rain, space and other growth conditions, which have a great impact on the growth and yield of crops. During the planting and growth of many crops, herbicides can be classified according to the mode of action, application site, and source of compounds. Divided into contact herbicides, systemic conduction herbicides and systemic conduction and contact comprehensive herbicides, and are divided into stem and leaf treatment agents, soil treatment agents, stem and leaf, soil treatment agents, ...
