Abstract

The invention relates to a novel nicotinamide compound, a preparation method thereof and a herbicide containing the compound. The compounds of the present invention can be used as herbicides for foliar treatment or soil treatment because they are highly safe to wheat or corn and have excellent herbicidal activity against narrow leaf weeds, nutgrass flatsedge weeds or broad leaf weeds.

Description

Technical field [0001] This application claims priority to Korean Application No. 10-2019-0130935 filed on October 21, 2019, and all contents disclosed in the specification and drawings of this application are incorporated herein by reference. [0002] The present invention relates to a novel nicotinamide compound, a preparation method thereof and a herbicide composition containing the compound. Background technique [0003] Generally, weed control is extremely important for improving agricultural productivity, and various herbicides have been used simultaneously. For example, triazine herbicides such as atrazine, or anilide herbicides such as alachlor or metolachlor have been used in corn cultivation. On the other hand, as non-selective herbicides, herbicides such as paraquat or glyphosate have been used. However, many weeds still cause losses in agriculture, and several existing insecticides have been reported to have developed resistance and failed to show satisfactory ...
