Various preservation methods at low temperature have been reported for several powdery mildew fungi, but the conidia of <I>Podosphaera aphanis </I>causing powdery mildew of strawberry could not be preserved either at low temperature or by freeze-drying and liquid-drying of conidial suspensions or diseased leaf discs. Here, we developed a new technique for a labor-saving preservation of the conidia of the fungus by using the aseptic seedling culture of strawberry. Conidia produced on the seedlings could be preserved at 5°C for six months. Using this method, we could obtain the stable stock cultures of 12 strains collected from various regions in Japan.
