Microbicidal compositions are described. The compositions comprise (a) 2-(Thiocyanomethylthio)benzothiazole (TCMTB) and (b) an N-alkyl heterocyclic compound of the formula:The variable 'n' ranges from 5 to 17, and the heterocyclic ring defined byis a substituted or unsubstituted ring having four to eight members. Components (a) and (b) are present in a combined amount effective to control the growth of at least one microorganism. Methods for controlling the growth of microorganisms on various substrates or in aqueous systems are also described. Also described is the industrial application of the microbicidal composition in the leather industry, the lumber industry, the papermaking industry, the textile industry, the agricultural industry, and the coating industry, as well as in aqueous systems.
