Abstract

Abstract Oxime carbamates and oxime carbonates of the formula ##STR1## in which Ar is optionally substituted phenyl, naphthyl, furan or thiophene, X is hydrogen, carboxylic acid, alkanoyl, halogen or alkyl, and R is a mono- or di-substituted amine, an optionally substituted alkoxy or an optionally substituted alkylthio group, the substituents of which include optionally-substituted hydrocarbyl groups and heterocyclic groups. Are suitable as antidotes for the protection of cultivated plants against harmful agricultural chemicals, in particular against herbicides which are insufficiently compatible with the cultivated plants. These compounds can be used either on their own or together with the agricultural chemicals. One of the possibilities offered is the dressing or immersion treatment of seed or of seedlings, of the crop to be protected, with solutions or dispersions said compounds.
