Microbicidal agents

Abstract

The invention relates to synergistic mixtures of o-phenylphenol and additional bactericides.

1 . A microbicidal composition comprising o-phenylphenol and at least one further compound from the group consisting of 
 bronopol (2-bromo-2-nitro-1,3-propanediol)    MIT (2-methyl-2H-isothiazol-3-one) and    Tektamer 38 (1,2-dibromo-2,4-dicyanobutane).    
     
     
         2 . The use of a composition as claimed in  claim 1  for protecting industrial materials against attack by fungi and algae.  
     
     
         3 . A method for protecting industrial materials against attack by fungi and algae, characterized in that the industrial materials are admixed or treated with a composition as claimed in  claim 1 .  
     
     
         4 . A process for preparing a composition as claimed in  claim 1 , characterized in that o-phenylphenol and at least one further compound from the group consisting of bronopol (2-bromo-2-nitro-1,3-propanediol), MIT (2-methyl-2H-isothiazol-3-one) and Tektamer 38 (1,2-dibromo-2,4-dicyanobutane) and, if appropriate, extenders-and, if-appropriate, surfactants are mixed.
