ABSTRACT:
Synergistic antialgal compositions comprising substituted fluoroalkyl diphenylethers and a material selected from the group consisting of sodium hypochlorite, halodialkylhydantoin, n-alkyl dimethyl benzylammonium chloride, 2,2-dibromo-3-nitrilopropionamide, 2-bromo-2-nitro-1,3-propanediol, poly[oxyethylene(dimethylimino)ethylene(dimethylimino)ethylene dichloride], 3-iodo-2-propynylbutylcarbamate, sodium N-methyldithiocarbamate, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, N-(phosphonomethyl)glycine and salts thereof, zinc bis(dimethyldithiocarbamate), p-tolyldiiodomethylsulfone and fatty acid salt in ratios to each other which exhibit synergism are disclosed. Particularly effective combinations are based on oxyfluorfen as the diphenylether for use in protecting aqueous systems, such as latices and cooling water systems, from algal growth.
