Agricultural fungicidal method

New diphenyl ether derivatives having one to three substituents selected from a halogen atom and a trifluoromethyl group at any optional one to three positions of the 2'-, 3'-, 4'-, 5'- and 6'-positions in one phenyl moiety and nitro group at the 4-position and unsubstituted or substituted aminosulfonyl group at the 3-position in another phenyl moiety. They have a superior herbicidal effect and can be prepared starting from a known 3-benzylmercapto compound through three steps.
