The present invention relates to a red tide preventive agent capable of effectively removing a red tide cause organism, and provides a red tide preventive agent composed of a lipophilic lipid, rhamnolipid and a chemical glycolipid sugar ester, and a span surfactant, which are produced from microorganisms. Since the red tide preventive agent of the present invention can use a low-cost raw material, it can be mass-produced, thereby reducing the processing cost when controlling red tide, and having a high biodegradation, there is no secondary environmental pollution when applied to seawater, and at low concentrations for a short time. Because it shows the effect, it can be useful for quick relief in case of red tide, not red tide prevention. |
