A 4-alkylideneamino-5-amino-1,2,4-triazol-3-(thi)-one of the formula ##STR371## R.sup.4 and R.sup.5 are identical or different and independently of one another represent hydrogen, or represent in each case straight-chain or branched alkyl having 1 to 8 carbon atoms, alkenyl having 2 to 8 carbon atom's, alkinyl having 2 to 8 carbon atoms, halogenoalkyl having 1 to 8 carbon atoms and 1 to 17 identical or different halogen atoms, halogenoalkenyl or halogenoalkinyl, in each case having 2 to 8 carbon atoms and 1 to 15, or 13, identical or different halogen atoms, cyanoalkyl having 1 to 8 carbon atoms, or alkoxyalkyl or alkylthioalkyl, in each case having up to 4 carbon atoms in the individual alkyl moieties, or represent cycloalkyl or cycloalkylalkyl, each of which has 3 to 8 carbon atoms in the cycloalkyl moiety and, where appropriate, 1 to 6 carbon atoms in the alkyl moiety and each of which is optionally monosubstituted to trisubstituted by identical or different substituents selected from the group consisting of halogen, cyano as well as in each case straight-chain or branched alkyl or halogenoalkyl, in each case having 1 to 4 carbon atoms and, where appropriate, 1 to 9 identical or different halogen atoms, or the radicals R.sup.4 and R.sup.5 furthermore represent aryl or aralkyl, each of which has 6 or 10 carbon atoms in the aryl moiety and, where appropriate, 1 to 4 carbon atoms in the straight-chain or branched alkyl moiety and each of which is optionally monosubstituted to trisubstituted by identical or different substituents selected from the group consisting of halogen, cyano, nitro, hydroxyl, in each case straight-chain or branched alkyl, alkoxy, alkylthio, halogenoalkyl, halogenoalkoxy, halogeno, alkylthio, alkylsulphinyl, alkylsulphonyl, halogeno-alkylsulphinyl, halogenoalkylsulphonyl, alkanoyl and alkoxycarbonyl, in each case having 1 to 6 carbon atoms in the alkyl moiety and, where appropriate, 1 to 9 halogen atoms, and R.sup.5 can also represent straight-chain or branched alkoxy having 1 to 8 carbon atoms, and

• R.sup.6 and R.sup.7 are identical or different and independently of one another represent in each case straight-chain or branched alkyl having 1 to 8 carbon atoms and optionally monosubstituted to trisubstituted by identical or different substituents selected from the group consisting of halogen or cyano, or the radicals R.sup.6 and R.sup.7 furthermore represent aralkyl which has 6 or 10 carbon atoms in the aryl moiety and, where appropriate, 1 to 4 carbon atoms in the straight-chain or branched alkyl moiety and each of which is optionally monosubstituted to trisubstituted by identical or different substituents selected from the group consisting of halogen, cyano, nitro, hydroxyl, in each case straight-chain or branched alkyl, alkoxy, alkylthio, halogenoalkyl, halogenoalkoxy, halogenoalkylthio, alkylsulphinyl, alkylsulphonyl, halogenoalkylsulphinyl, halogenoalkylsulphonyl, alkanoyl and alkoxycarbonyl, in each case having 1 to 6 carbon atoms in the alkyl moiety and, where appropriate, 1 to 9 halogen atoms.
