Thirty‐five carbocyanines were examined for fungitoxicity and some were found to be active. This newly found biological property was limited to carbocyanines of a fairly low molecular weight, and was dependent on the heterocyclic base or bases from which the carbocyanine was derived. Alkyl substituents enhanced the fungitoxicity of the dyes irrespective of their position. Tests with some dyes showed that these penetrated to the protoplasts of the spores, staining them irreversibly.
