Ternary compound herbicidal composition

Abstract

The invention discloses a ternary compound herbicidal composition. The composition is prepared from the following components in percentage by weight: 10 to 80% of active ingredient and 20 to 90% of auxiliary component of pesticide formulation, wherein the first active ingredient is diflufenican, the second active ingredient is isoproturon, the third active ingredient is any one of thifensulfuron methyl, 2-methyl-4-chlorophenoxyacetic acid or salts or esters thereof, and the weight ratio of the first active ingredient, the second active ingredient to the third active ingredient is (10 to 30) to (50 to 150) to ( 1 to 8). The ternary compound herbicidal composition provided by the invention has the advantages of obviously expanding the herbicidal spectrum and improving the overall control effect on weeds in a wheat field. Meanwhile, the composition is safe to wheat, and is a very good novel pharmaceutical composition for controlling annual weeds in the wheat field.

Description

technical field [0001] The invention belongs to the field of agrochemicals, and in particular relates to a herbicidal composition aimed at solving the problem of controlling annual weeds in wheat fields. Background technique [0002] Diflufenican belongs to the amide herbicides and carotenoid biosynthesis inhibitors. The content of carotenoids in the treated plants decreased, which in turn resulted in the destruction of chlorophyll, rupture of cell membranes, weeds showed discoloration or whiteness of young shoots, and finally led to death. It can be used for the pre-emergence or post-emergence control of wheat after sowing, to prevent and control pig worms, field viola, mother-in-law, and Baogai grass, etc. [0003] Isoproturon (isoproturon) belongs to photosynthetic electron transport inhibitor, belongs to substituted urea selective pre-emergence and post-emergence herbicide, the drug is mainly absorbed by weed roots and stems and leaves, and conducts upward with water in...

AI Technical Summary

Problems solved by technology

[0005] 2-methyl-4-chloro (MCPA) or its salt or its ester is a phenoxyacetic acid selective hormone-type herbicide, which is easily absorbed by roots and leaves. It is mainly used to control various annual and Perennial broad-leaved weeds, it has a significant effect on Cyperus cyperi, three-edge grass, sausage, bermudagrass, and sagittarius, but it is basically ineffective against gramineous weeds

[0006] Herbicide varieties containing a single active component have defects in weed control to varying degrees, such as weeds are prone to resistance after continuous use, the herbicide spectrum becomes narrower, and environmental pollution is caused.
