Abstract

The invention discloses an effectiveness-enhanced glyphosate weeding combination and a preparation method for dispersible granule, water soluble powder and aqueous solution agent thereof. Compared with the glyphosate which is independently used, the invention has the advantages that the combination can greatly promote the weeding activity of the glyphosate, the use amount of the glyphosate is reduced and the use efficiency is improved.

Description

technical field [0001] The invention relates to a synergistic herbicidal composition, especially a synergistic composition containing glyphosate. Background technique [0002] Glyphosate (glyphosate), scientific name N-(phosphonomethyl) glycine, N-(phosphonomethyl) aminoacetic acid (Phosphonomethyl Imino Acetic Acid), is an organophosphorus herbicide developed by Monsanto Company of the United States. As a non-selective, non-residue post-emergence herbicide, glyphosate is absorbed through plant leaves and non-woody stems and leaves, and is transmitted to all parts of the plant. Very effective against deep rooting perennial weeds and annual and biennial grasses, sedges and broadleaf weeds. The most prominent feature of glyphosate is that it can be absorbed by stems and leaves and transmitted downwards to underground rhizomes and tillers, which is extremely destructive to the underground tissues of weeds. Its herbicidal principle is mainly through inhibiting the activity of ...
