| 摘要 |
The present invention is directed to heterocycle-substituted benzene derivatives represented by a general formula ÄIÜ; <CHEM> Wherein R<1> is halogeno, C1-C4 alkyl, C1-C4 alkoxy, nitro, cyano, C1-C4 haloalkyl or the like; R<2> is halogeno, nitro, cyano, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 haloalkyl, C1-C4 haloalkoxy, C1-C4 alkylthio or the like; R<3> and R<4> each independently represent hydrogen, C1-C4 alkyl or the like; T represents cyclohexanedione-1,3-dione cyclic group represented by a general formula ÄIIÜ; <CHEM> wherein R<5>, R<6>, R<7>, R<8>, R<9> and R<10> are each independently halogeno, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 alkoxy or the like, or either R<5> or R<6> and either R<7> or R<8> may together form C1-C5 alkylene chain, and the salts thereof. The compounds according to the present invention have excellent herbicidal activity, and the herbicidal formulations prepared according to the present invention containing the inventive compounds are useful as hercicides being selectively-safe to objective agricultural crops. |
