N-Aryl-N'-(cyclo)-alkyl-thioureas of the formula <IMAGE> (I) in which R1 represents alkyl-(C1-C6) or cycloalkyl-(C3-C7), R2 represents alkyl-(C2-C6) or cycloalkyl-(C3-C7), R3 represents alkyl-(C1-C6), alkenyl-(C3-C6), cycloalkyl-(C3-C7), cycloalkenyl-(C5-C7) or halogen, n represents 0, 1 or 2, and R7 represents optionally substituted cycloalkyl-(C3-C10), optionally substituted cycloalkenyl-(C5-C10) or the radical <IMAGE> in which R4 represents hydrogen, alkyl-(C1-C6) or cycloalkyl-(C3-C7) and R5 and R6 may be identical or different and represent alkyl-(C1-C6) or cycloalkyl-(C3-C7), 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 <IMAGE> (II) with amines of the formula H2N-R7. |
