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 from 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 herbicidal composition comprising the compound. Background technique [0003] In general, weed control is extremely important to improve agricultural productivity, and various herbicides have been used at the same time. 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 it has been reported that many existing insecticides have developed resistance without showing satisfactory...
