FIELD: chemistry.
SUBSTANCE: invention relates to biocides. The synergetic antimicrobial composition contains glyphosate or zinc salt thereof and 3-iodo-2-propynyl butylcarbamate. A coating composition contains said synergetic antimicrobial composition. A dry film is obtained from said coating composition. A zinc salt of glyphosate is obtained by: (a) obtaining an aqueous glyphosate solution, (b) mixing said aqueous glyphosate solution with an aqueous solution of an inorganic zinc salt. Said mixing is carried out while keeping pH of the mixture not higher than 5.
