Problems solved by technology

However, with the extensive use of dicamba, many weeds have gradually developed resistance to it, seriously affecting the use of dicamba
[0005] The above two herbicides are different in chemical composition, structure and physical and chemical properties, so their herbicidal ability and scope are also different, and there are certain deficiencies in their respective use, and it is easy to form drug dependence. Therefore, the study of herbicide mixtures Agents have very important ecological and environmental significance

Abstract

The invention discloses a weeding composition containing MCPA (2-methyl-4-chloro-phenoxyacetic acid) and dicamba. The weeding composition comprises raw material medicines and auxiliary materials, wherein the raw material medicines comprise 2-methyl-4-chloro-phenoxyacetic acid and dicamba. The invention further discloses a preparation method and an application of the weeding composition. Compared with the prior art, by mixing effective components of weed killers, the weeding composition has the benefits of expanding weeding spectrum, improving weeding effect, prolonging the suitable period of drug application, reducing drug harm, reducing activity of drug residue, holding over generation and development of drug resistance of the weed killers, and having an important ecological and environmental protection significance.

Description

Technical field [0001] The present invention involves a weeding composition and its preparation methods and applications containing MCPA and wheat awe, which belongs to the field of pesticide technology. Background technique [0002] With the further development of herbicide production and application, the mixing between herbicides has gradually developed.my country's mixed research on herbicides also attaches great importance to it. It is widely recognized as one of the important measures for the reasonable use of herbicides. It has developed a series of weeding mixtures and made great progress. [0003] MCPA, molecular formula: C 9 H 9 CLO 3 , Chemical name: 2-methyl-4 chloride.MCPA is a hormone -type selective herbicide, which is easy to absorb and conduct the roots and leaves, destroying the metabolism of plants, causing plant deformation, swollen mildew, and dying. It is suitable for rice, wheat and other dry land crops, Zexie, Nori, and other broad -leaved weeds, the worst ...
