Abstract Freshly produced conidia were collected from barley grain medium by washing with distilled water, the spore suspension is filtered onto filter paper in a funnal, dried at 30-35℃, and stored in desiccator at indoor, 4℃ and -20℃.The conidia retained their original level of viability and pathogenicity after 10 months indoor,there are further preservation times at 4℃ and -20℃. Thus,the problem is solved that culture rice seedling can not synchronize with sporulation culture of blast fungus during the artifical inoculation.
