<p>Novel amino-substituted derivatives represented by general formula (I) exhibiting a herbicidal activity higher than those of known analogues thereof, a process for the preparation thereof, and a herbicide comprising the same as the active principle. In said formula, A is N or CR3; Z is O or S; Q is a five- or six-membered heterocycle; R1 and R2 are each independently H, C1-C6 alkyl, C1-C6 alkoxy or the like; R3 is H, C1-C6 alkyl, halogeno or the like; and X is NR4R5 (wherein R4 and R5 are each independently H, C1-C6 alkyl, C3-C7 cycloalkyl, C1-C6 alcoxy, C1-C6 alkyl or the like, or R4 and R5 may together form a ring.</p> |
