PROBLEM TO BE SOLVED: To solve such problems that creation of herbicidal composition having a broader weeding spectrum, high activity and a long sustained effect is desired because there are a plurality of species of weeds to be the object of control and their emergence extends over a long period of time, though a large number of herbicidal composition are developed and used at present.SOLUTION: This herbicidal composition includes (a) flazasulfuron or its salt, and (b) metribuzin or its salt, as effective components.COPYRIGHT: (C)2013,JPO&INPIT【課題】現在、数多くの除草組成物が開発され使用されているが、防除の対象となる雑草は種類も多く、発生も長期にわたるため、より幅広い殺草スペクトルを持ち、高活性で且つ持続効果の長い除草組成物の創製が望まれている。【解決手段】(a)フラザスルフロン又はその塩と(b)メトリブジン又はその塩とを有効成分として含有する除草組成物。【選択図】 図1
