The present invention relates to certain processes and compositions useful for inhibiting the growth of slime in water and, in particular, water used for industrial purposes; for example, in the manufacture of paper and pulp paper, in cooling water systems and in effluent water treatment. The novel processes and compositions of the present invention are processes or mixtures which show unexpected synergistic activity against microorganisms, including bacteria, fungi and algae, which produce, in aqueous systems or bodies, slime which is objectionable from either an operational or aesthetic point of view. Specifically, the invention is directed to the use of compositions comprising .alpha.-Bromo-p-methylacetophenone and 1,3-dichloroacetone oxime acetate.
