Benzimidazole derivatives of the formula ##STR1## in which R is an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 3 to 5 carbon atoms, an alkynyl group having 3 to 5 carbon atoms or a benzyl group, which is unsubstituted or monosubstituted to disubstituted by a methyl group, halogen or a nitro group; R.sub.1 is hydrogen, an alkanoyl group having 1 to 4 carbon atoms, an alkoxycarbonyl group having 1 to 4 carbon atoms, a N,N-dialkylcarbamoyl group or N,N-dialkylthiocarbamoyl group, each having 1 to 4 carbon atoms in the alkyl groups, an alkylsulphonyl group having 1 to 4 carbon atoms, a benzoyl group, a phenylsulphonyl group, a 4-methylphenylsulphonyl group or the radical, ##STR2## in which Q is a carbonyl group, a thiocarbonyl group or an oxalyl group; R.sub.2 is hydrogen, halogen or a methyl group; R.sub.3 is hydrogen, halogen, a methyl group or an alkoxy group having 1 to 4 carbon atoms; R.sub.4 is hydrogen, halogen or a methyl group; X is oxygen or sulphur; Y is halogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a methylthio group, a methylsulphinyl group, a methylsulphonyl group, a trifluoromethyl group, a nitro group, a hydroxyl group, a cyano group or an alkanoyl group having 1 to 4 carbon atoms in the alkyl moiety m is 0, 1, 2 or 3; and n is 0, 1 or 2. Included are, if R.sub.1 is not hydrogen, the tautomeric compounds of the formula I. The compounds are effective for combating helminths in domestic and useful animals.
