Zusammenfassung:Hydroxypyridone carboxamides of the formula I in which the substituents have the following meanings: X is oxygen or sulphur; R and R independently of one another are hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl or alkoxy, where the abovementioned organic radicals can optionally be substituted; R is hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, halogen or nitro; R is alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, alkylthio, phenyl or a 5- or 6-membered heterocyclic, aliphatic or aromatic radical containing one to three hetero atoms selected from the group consisting of oxygen, sulphur or nitrogen, where the abovementioned radicals are optionally substituted; with the exception of 6-methyl-4-hydroxypyrid-2-one-3-carboxamide and N-tert-butyl-6-methyl-4-hydroxypyrid-2-one-3-carboxamide.
