Many herbicidal compositions have been developed and practically used.However, types of weeds to be controlled are also many, and their emergenceextends over a long period. Accordingly, it is desired that a herbicidalcomposition be developed which has a wider herbicidal spectrum and which ishighly active and has a long lasting effect. As a result of a research tosolve such problems, the present inventors have found it possible to obtain ahighly practical herbicidal composition by a combined use of (A) 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide or itssalt and (B) N2-tert-butyl-6-chloro-N4-ethyl-1,3,5-triazine-2,4-diamine or itssalt, and thus have accomplished the present invention.
