Abstract

For controlling parasitic protozoa and fish parasites, the novel substituted hexahydro-1,2,4-triazinediones of the formula ##STR1## in which R.sup.1 represents a heteroaromatic radical which is bonded via carbon and is optionally substituted, PA1 X represents O, S, SO, SO.sub.2 or --CR.sup.5 (CN)--, PA1 R.sup.2 represents one or more identical or different radicals from the group consisting of hydrogen, halogen, nitro, alkyl, alkoxy, halogenoalkyl, halogenoalkoxy, alkylthio and halogenoalkylthio, PA1 R.sup.3 and R.sup.4, independently of one another, represent hydrogen, optionally substituted alkyl, alkenyl, alkinyl or aralkyl, and PA1 R.sup.5 represents hydrogen or alkyl, excepting compounds in which X represents --CR.sup.5 (CN)--and PA1 R.sup.1 represents thienyl. Also novel intermediates of the formulae ##STR2##
