|内容記述: || In October 2008, brown leaf spot was first detected on the leaves of a rose red lily (Lilium speciosum var. speciosum L.) in Machida, Tokyo, Japan and ever since has been observed annually in August-October. The aim of this study was to clarify the pathogenic source of this disease. Typical symptoms observed were brown leaf spots surrounding the yellow leaf margins. Over time, the lesions enlarged but did not cover the entire leaf. The causative agent was a fungal species member of Pestalotiopsis, as determined via conidial morphology and molecular data. To our knowledge, this is the first report of Pestalotiopsis sp. causing brown leaf spot disease in lily in Japan. We propose to call this disease, brown leaf spot, “Kasshoku-hanyou-byo” in Japanese.|
