Abstract
Synergistic combinations of active compounds consisting of benzimidazolyl-alkyl-carbonates and (2,2'-dihydroxy-5,5'-dichlor)-diphenyl-methane or 2-hydroxy-diphenyl have a strong activity against micro-organisms. The combination can be employed e.g. for protecting industrial materials against microbicidal decomposition.
