Zusammenfassung:3-carbamoyl-4-hydroxy-couramins for combating parasitic helminths of the formula in which R1 represents hydrogen, halogen, alkyl, NO2, CN or alkoxy, X represents O, S, SO or SO2 R2 represents alkyl, halogenoalkyl, phenyl, naphthyl or pyridyl, which can optionally be substituted; or the radical -X-R2, together with the radical R3 can also form an alkylenedioxy (-O-alk-O), halogenoalkylenedioxy, oxyalkyleneoxyalkylene (-O-Alk-O-Alk-) or oxyhalogenoalkylene-oxyhalogenoalkylene bridge; and R3 and R4 independently of one another represent hydrogen, halogen, CN, OH, NO2, amino, mono- or dialklylamino, alkyl, halogenoalkyl, aralkyl or aryl, which can optionally be substituted, can be used for combating parasitic helminths.
