PURPOSE:To provide an antibacterial agent containing 4,5-dichloro-2- octylisothiazolin-3-one and an antibacterial agent such as methylene bisthiocyanate, etc., exhibiting excellent antibacterial activity by synergistic effect, capable of reducing treatment cost and useful for the treatment of irrigation system. CONSTITUTION:The objective agent contains (A) 4,5-dichloro-2-octylisothiazolin-3- one and (B) one or more components selected from methylene bisthiocyanate, 2,2-dibromo-3-nitrilopropionamide, 1,3-dibromo-5,5-dimethylhydantoin, 4,5- dichloro-1,2-dithiol-3-one and hexabromodimethylsulfone. The ratio of the component A to the component B is usually 10:1-1:200. The components are compounded with each other and applied to the water system to be treated. EFFECT:The antibacterial spectrum can be broadened compared with the separate use of each component. The development of resistant strain is suppressed and the agent can be used over a long period. |
