Abstract

N-Aryl-N'-(cyclo)-alkyl-thioureas of the formula ##STR1## in which R.sup.1 represents alkyl-(C.sub.1 -C.sub.6) or cycloalkyl-(C.sub.3 -C.sub.7), PA1 R.sup.2 represents alkyl-(C.sub.2 -C.sub.6) or cycloalkyl-(C.sub.3 -C.sub.7), PA1 R.sup.3 represents alkyl-(C.sub.1 -C.sub.6), alkenyl-(C.sub.3 -C.sub.6), cycloalkyl-(C.sub.3 -C.sub.7), cycloalkenyl-(C.sub.5 -C.sub.7) or halogen, PA1 n represents 0, 1 or 2, and PA1 R.sup.7 represents optionally substituted cycloalkyl-(C.sub.3 -C.sub.10), optionally substituted cycloalkenyl-(C.sub.5 -C.sub.10) or the radical ##STR2## in which R.sup.4 represents hydrogen, alkyl-(C.sub.1 -C.sub.6) or cycloalkyl-(C.sub.3 -C.sub.7) and PA1 R.sup.5 and R.sup.6 may be identical or different and represent alkyl-(C.sub.1 -C.sub.6) or cycloalkyl-(C.sub.3 -C.sub.7), and acid addition salts thereof, are useful for their ectoparasiticidal, insecticidal, fungicidal and acaricidal effects. These compounds may be produced, inter alia, by reacting aryl isothiocyanates of the formula ##STR3## with amines of the formula H.sub.2 N--R.sup.7.
