Problems solved by technology

However, glufosinate-ammonium also has the following disadvantages: its control effect on some perennial tolerant plants (such as tall, lignified weeds) is poor; the control of older weeds is not complete, after using glufosinate, older weeds grass prone to resurgence
It has high selectivity between gramineous weeds and dicotyledonous crops, and is used for the control of crabgrass, okra, goosegrass, barnyardgrass, Annual grass weeds such as foxtail and stephatia and perennial grass weeds such as bermudagrass and imperata, but ineffective against broadleaf grass and sedge

Abstract

The invention discloses a herbicide composition and application thereof, and relates to the technical field of pesticide herbicides, the effective components of the herbicide composition comprise glufosinate-ammonium, 2-methyl-4-chloro-phenoxyacetic acid salt or 2-methyl-4-chloro-phenoxyacetic acid ester and haloxyfop-R-methyl, the mass fraction ratio of the glufosinate-ammonium to the 2-methyl-4-chloro-phenoxyacetic acid salt or the 2-methyl-4-chloro-phenoxyacetic acid ester to the haloxyfop-R-methyl in the herbicide composition is (8-32): (10-50): (1-5), and the total mass percent of the glufosinate-ammonium, the 2-methyl-4-chloro-phenoxyacetic acid salt or the 2-methyl-4-chloro-phenoxyacetic acid ester and the haloxyfop-R-methyl in the herbicide composition is 20%-80%. Compared with a single agent and a composition containing two groups of effective components, the herbicide composition has the advantages that the control effect is obviously improved, the use dosage of pesticides is reduced, the pesticide use frequency is reduced, the pesticide use cost is reduced, and the adverse influence of the pesticides on the ecological environment is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition containing glufosinate-ammonium, dimethyltetrachloride and high-efficiency haloxyfop-pyl and application thereof. Background technique [0002] Glufosinate-ammonium: Glufosinate-ammonium is a broad-spectrum contact herbicide with broad herbicidal spectrum, low toxicity, high activity and good environmental compatibility, and has broad application prospects. Glufosinate-ammonium has a wide herbicidal spectrum and has a good control effect on almost the vast majority of annual or even perennial weeds in farmland. It can be used in orchards, vineyards, potato fields, non-cultivated land, etc. to control annual and perennial dicotyledonous and gramineous weeds. Grass, such as: Mai Niang, crabgrass, barnyard barnyardgrass, wild barley, ryegrass multiflora, foxtail, wild wheat, etc. It can also control broad-leaved weeds such as quinoa, amaranth, polygonum,...
