Abstract

The invention discloses water-dispersible granules containing glufosinate-ammonium, fluoroglycofen-ethyl and quizalofop-p-ethyl and belongs to the field of weeding. The water-dispersible granules contain the following ingredients in percentage by weight: 30%-60% of glufosinate-ammonium, 1%-10% of fluoroglycofen-ethyl, 5%-12% of quizalofop-p-ethyl, 2%-5% of humectant, 2%-5% of dispersant, 1%-3% ofdisintegrant, 2%-4% of organosilicone surfactant and the balance of fillers. The water-dispersible granules containing the glufosinate-ammonium, the fluoroglycofen-ethyl and the quizalofop-p-ethyl, disclosed by the invention, are good in weeding effect, the consumption of pesticides is lowered, and the potency is stable.

Description

technical field [0001] The invention relates to the field of weeding, in particular to a water-dispersible granule containing glufosinate-ammonium, acifluorfen and quizalofop-p-ethyl. Background technique [0002] Glufosinate-ammonium is a phosphonic acid herbicide that can inhibit glutamine synthetase in the plant nitrogen metabolism pathway, thereby interfering with plant metabolism and causing plant death. Glufosinate-ammonium has the characteristics of broad herbicidal spectrum, low toxicity, high activity and good environmental compatibility, and its activity speed is slower than that of paraquat and better than that of glyphosate. At present, it has become a non-selective herbicide coexisting with glyphosate and paraquat, and has broad application prospects. Many weeds are sensitive to glufosinate and can be used as a substitute for glyphosate in areas where glyphosate is resistant. Acefluorfen is a diphenyl ether herbicide and an inhibitor of protoporphyrin oxidase....
