Abstract

Alkoxycarbonyl-substituted hydroxythiophenecarboxamides of the formula ##STR1## in which R.sup.1 represents alkyl, alkoxyalkyl, alkylthioalkyl, fluoroalkyl, cyanoalkyl, alkenyl or alkinyl or represents cycloalkyl, PA0 R.sup.2 represents alkyl or optionally substituted phenyl, PA0 R.sup.3 represents alkyl, alkoxyalkyl, alkylthioalkyl, cyanoalkyl, fluoroalkyl, alkenyl, alkinyl, cycloalkyl or alkoxy and PA0 R.sup.4 represents hydrogen, alkyl, alkoxyalkyl, alkylthioalkyl, fluoroalkyl, cyanoalkyl, alkenyl, alkinyl or cycloalkyl, or PA0 R.sup.3 and R.sup.4, together with the nitrogen atom, represent a heterocyclic radical which is optionally substituted by alkyl and can be further substituted in the alkylene chain by oxygen, sulphur or nitrogen, are useful as fungicides and intermediates.
