Bacterial ring rot of potato is one of the most serious potato plant and tuber diseases.  Laminaria japonica  extract was investigated for its antimicrobial activity against  Clavibater michiganense  subsp.  sepedonicum  (Spieckermann & Kotthoff) Davis et al., the causative agent of bacterial ring rot of potato. The results showed that the optimum extraction conditions of antimicrobial substances from  L. japonica  were an extraction temperature of 80°C, an extraction time of 12 h, and a solid to liquid ratio of 1∶25. Active compounds of  L. japonica  were isolated by solvent partition, thin layer chromatography (TLC) and column chromatography. All nineteen fractionations had antimicrobial activities against  C. michiganense  subsp.  sepedonicum , while Fractionation three (Fr.3) had the highest ( P <0.05) antimicrobial activity. Chemical composition analysis identified a total of 26 components in Fr.3. The main constituents of Fr.3 were alkanes (80.97%), esters (5.24%), acids (4.87%) and alcohols (2.21%). Antimicrobial activity of Fr.3 against  C. michiganense  subsp.  sepedonicum  could be attributed to its ability to damage the cell wall and cell membrane, induce the production of reactive oxygen species (ROS), increase cytosolic Ca 2+  concentration, inhibit the glycolytic pathway (EMP) and tricarboxylic acid (TCA) cycle, inhibit protein and nucleic acid synthesis, and disrupt the normal cycle of DNA replication. These findings indicate that  L. japonica  extracts have potential for inhibiting  C. michiganense  subsp.  sepedonicum .
