Abstract

The invention discloses a synergic glyphosate weeding composition containing humic acid and preparation methods of dispersible granula, soluble powder and water aqua thereof. Compared with the respectively used glyphosate, the composition can greatly improve the weeding activity of the glyphosate, reduce the dosage of the glyphosate and improve the utilization efficient.

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 ...
