| Abstract: | Bacillus SA2 was isolated from the soil of plantting wasabi in Sichuan Province which could inhibit Phoma wasabiae Yokogi. It was identified as Bacillus thuringiensis by physiological, biochemical test and molecular systematic analysis. The texts exhibited that SA2 could control the disease by P. wasabiae and cortrol efficaey on the diseace in the potted plant and the field test reached 85.57% and 78.98 % respectively. The result indicated that the antifungal strain in the study well worth developing and applying for the biocontrol of the disease. |
