Abstract: The invention relates to an aqueous dispersion which includes a mixture composed of the active ingredients carbendazime, 2-(thiocyanomethylthio)-benzothiazole and 2-methylthio-4-t-butyl-amino-6-cyclopropylamino-s-triazine. Further active ingredients with algicidal or fungicidal effect can optionally be present in the dispersion. The dispersion can be used for the fungicidal and algistatic finishing of paints, varnishes and plasters.
