R 1H, 1-6C alkyl or 1-4C alkoxy-1-6C alkyl; R 2H, 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl, 1-4C alkoxy-1-6C alkyl, di-1-4C alkoxy-1-6C alkyl, 1-4C alkoxy-1-4C alkoxy-1-6C alkyl, 3-6C cycloalkyl or 3-6C cycloalkyl-1-6C alkyl; Y' : 1-6C alkylsulfonyl, 1-4C alkoxy-1-6C alkylsulfonyl, phenylsulfonyl, thiophenyl-2-sulfonyl, benzoyl, 1-4C alkylbenzoyl-1-6C alkyl or benzyl, (all optionally mono- to tri-substituted by halo, 1-4C alkyl or 1-4C alkoxy), or H. An independent claim is included for a herbicidal composition comprises the compound (I). [Image] ACTIVITY : Herbicide; Plant growth inhibitor; Seed germination Inhibitor. The herbicide efficacy of [3-(cyclopropylmethyl-methyl-amino) -4-methanesulfonyl-2-methyl-phenyl]-(5-hydroxy-1,3-dimethyl-1H-pyrazol-4-yl)-methanone (Ie) was evaluated for pre-emergence herbicidal action against harmful plants e.g. Viola tricolor. The compound (Ie) showed 100% controlled of Viola tricolor. MECHANISM OF ACTION : None given.
