FIELD: chemistry.

SUBSTANCE: invention relates to protection of objects from microorganism growths. The composition against fouling organisms contains 4-bromo-2-(4-chlorophenyl)-5-(trifluoromethyl)-1n-pyrrole-3-carbonitrile or salts thereof, as a component (1) and as a component (11) of a copper or zinc compound selected from Cu₂O, Cu(OH)₂, CuSO₄, copper pyrithione, CuSCN, CuCO₃, ZnCI₂, ZnSO₄, zineb and zinc pyrithione. In the composition, the weight ratio of component (I) to one of components (II) ranges from 10:1 to 1:10. When component (II) is zinc pyrithione, the weight ratio of component (I) to zinc pyrithione ranges from 2:1 and 1:2. The preparation against fouling organisms contains a 4-bromo-2-(4-chlorophenyl)-5-(trifluoromethyl)-1n-pyrrole-3-carbonitrile component or salt thereof as component (I) and component (II), selected from Cu₂O, Cu(OH)₂, CuSO₄, copper pyrithione, CuSCN, CuCO₃, ZnCI₂, ZnSO₄, zineb and zinc pyrithione. The preparation is used as a combination for simultaneous or successive application, in which the weight ratio of component (I) to one of components (II) ranges from 10:1 to 1:10. When component (II) is zinc pyrithione, the weight ratio of component (I) to zinc pyrithione ranges from 2:1 to 1:2.

EFFECT: invention increases efficiency of the composition and the preparation.
