Abstract
The present invention provides a method for combating harmful microorganisms, which comprises applying to a desired site an effective amount of 2-hydroxy-benzophenone of the formula ##SPC1## Wherein Z.sub.1 denotes halogen or alkyl, X.sub.1 and Y.sub.1 each denote hydrogen, halogen, alkyl, cycloalkyl, benzene or substituted benzene, X.sub.2, X.sub.3, X.sub.4, Y.sub.2 and Y.sub.3 each denote hydrogen, halogen or alkyl and X.sub.5 denotes hydrogen or halogen, with the number of the alkyl, benzene and cyclohexyl radicals as substituents being together at most 4. The anti-bacterial range of these 2-hydroxy benzophenones extends both to gram-positive and gram-negative bacteria.
