摘要

A 3-azabicyclo[3.1.0]hexane-2-one derivative represented by the following formula (I), and a herbicidal composition containing the same as a herbicidally active ingredient: (wherein X is a hydrogen atom, a halogen atom, an alkyl group having 1 to 3 carbon atoms, an alkoxy group having 1 to 3 carbon atoms or a haloalkyl group having 1 to 3 carbon atoms; Y is a hydrogen atom, a halogen atom or an alkyl group having 1 to 3 carbon atoms; R₁ is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; R₂ is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; m is an integer of 1 to 3; n is an integer of 1 or 2; and when m is 2 or 3, the groups represented by X may be identical or different, and when n is 2, the groups represented by Y may be identical or different).
