HERBICIDE AND METHOD OF PRODUCING OF NOVEL ETHERS AND ESTERS OF OXIMES OF DIPHENYL ETHERS

摘要

The invention relates to novel oxime derivatives of diphenyl ethers of the formula IMAGE wherein Q is an aliphatic or araliphatic ether or ester radical, R1 is halogen or a nitro, cyano or trifluoromethyl group, each of R2 and R3 is hydrogen, halogen or a nitro or cyano group, R4 is hydrogen or halogen and X is hydrogen, halogen or a member selected from the group consisting of cyano, nitro, lower alkyl, lower alkanoyl, carboxylic acid lower alkyl ester or carboxamide. These compounds have good selective herbicidal action, they inhibit plant growth, and can be employed as safeners for protecting cultivated plants from the phytotoxic action of aggressive agrochemicals.
