The present invention is directed to heterocycle-substitutednbenzene derivatives represented by a general formula [I];n n Wherein R 1 is halogeno, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, nitro, cyano, C 1 -C 4 nhaloalkyl or the like; R 2 is halogeno, nitro, cyano, C 1 -C 4 alkyl, C 1 -C 4 nalkoxy, C 1 -C 4 haloalkyl, C 1 -C 4 haloalkoxy, C 1 -C 4 alkylthio or the like; R 3 and R 4 each independently represent hydrogen, C 1 -C 4 alkyl or thenlike; T represents cyclohexanedione-1,3-dione cyclic group representednby a general formula [II];n nwherein R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are each independently halogeno, C 1 -C 4 nalkyl, C 1 -C 4 haloalkyl, C 1 -C 4 alkoxy or the like, or either R 5 or R 6 nand either R 7 or R 8 may together form C 1 -C 5 alkylene chain, and thensalts thereof. The compounds according to the present invention havenexcellent herbicidal activity, and the herbicidal formulations preparednaccording to the present invention containing the inventive compoundsnare useful as hercicides being selectively-safe to objectivenagricultural crops. |
