Abstract

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

Description

technical field [0001] The present invention relates to a herbicidal composition containing (A) 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide or a salt thereof (hereinafter referred to as compound A) and (B) N 2 -tert-butyl-6-chloro-N 4 - Ethyl-1,3,5-triazine-2,4-diamine or a salt thereof (hereinafter abbreviated as compound B). Background technique [0002] Patent Document 1 discloses Compound A, but does not disclose its use in combination with Compound B. [0003] Patent Document 1: EP0232067A Contents of the invention [0004] The problem to be solved by the present invention [0005] Various herbicidal compositions have been developed and used in practice. However, there are many types of grasses that need to be controlled, and they persist over long periods of time. Therefore, it is desirable to develop herbicidal compositions with broad-spectrum herbicidal action, high activity and long-lasting effect. [0006] way to solve the pr...
