An N-acyl-N-phenyltetrahydrophthalamic acid derivative represented by general formula (I), a process for producing the same, and a herbicide containing the same as the active ingredient: wherein X and Y represent each independently hydrogen or halogen; R1 represents hydrogen, halogen, lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkoxyalkoxy or lower alkoxycarbonylalkoxy; R2 represents lower alkyl, halogenated lower alkyl, or (un)substituted phenyl; and R3 represents lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkoxyalkoxy, benzyloxy, or lower alkoxycarbonylalkoxy. The herbicide is widely applicable to upland fields, paddy fields, orchards, pastures, turfs, forests, non-crop lands and so forth, and is highly safe to crops, thus proving very useful. |
