Abstract of the disclosure: There are presented new diphenyl ether derivatives having a substituent selected from a halogen atom, a trifluoro- methyl group and a methoxy group at the 4-position in one phenyl moiety, having optionally also halo-substituents at the 2- and 5-positions, and having a nitro group at the 4'-position and a substituent selected from an unsubstituted or substituted (1,3-dioxolane-4-yl)methoxy group, an unsub- stituted or substituted (1,3-dioxa-5-cyclohexyloxy) group and an alkyl- or (substituted)amino-sulfonyloxy group at the 3'-position in the other phenyl moiety. They exhibit improved herbicidal effects on various weeds without any adverse phytotoxic effect on crops, e.g. rice seedlings.
