PROBLEM TO BE SOLVED: To provide a safe and efficient method for producing a sustained-release slime control composition containing a bactericidal component against bacteria such as iron bacteria, etc., and a method for concretely installing the composition irrespectively of freshwater and seawater. SOLUTION: The method for producing a sustained-release slime control composition includes a process for heating and mixing (a) a higher fatty acid and a polyethylene glycol as binders solid at normal temperature with (b) one or more as a bactericidal component selected from the group consisting of dimethyl didecyl ammonium chloride, dimethyl isononyl decyl ammonium chloride, dimethyl dioctyl ammonium chloride, benzethonium chloride, copper sulfate and copper terephthalate and (c) one or more as an auxiliary selected from the group consisting of a polyvinyl alcohol, an oil-absorbing fine powder and a physicochemical regulator and then a process for casting the liquid composition obtained by heating and mixing into a mold, allowing the composition to stand naturally or forcedly reducing the temperature of the composition to solidify and mold the composition.
