At present, various herbicidal compositions have been developed and used, but they are not necessarily sufficient to control undesired plants such as weeds to be controlled, and a highly active herbicidal composition has been desired. A herbicidal composition comprising 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridylsulfonyl) urea or its salt and 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide or its salt, and a method for controlling undesired plants using it.
