Abstract
Abstract Substituted benzylimidazolium salts of the formula ##STR1## where R 1 , R 2 and R 3 are identical or different and are each hydrogen, C 1 -C 4 -alkyl or halogen, R 4 is alkyl of 8 to 14 carbon atoms or benzyl which is unsubstituted or substituted by halogen or alkyl, R 5 is hydrogen, alkyl of 1 to 8 carbon atoms, phenyl or benzyl, R 6 is alkyl of 1 to 4 carbon atoms or halogen, R 7 is alkyl of 1 to 4 carbon atoms or halogen and X is an anion of an acid, in particular of a hydrohalic acid, and microbicides containing these compounds.
