First Occurrence of Gray Mold of Celery Caused by Botrytis cinerea in Japan

Abstract

Gray mold of celery, Apium graveolens L., occurred on Chichijima in Ogasawara(Bonin) Islands in 2007. The pathogen isolated from the diseased plants was identified as Botrytis cinerea Persoon: Fries. An inoculation test confirmed that this fungus was the causal agent of this disease. This is the first report of this disease in Japan.
