Abstract

Studies on the leaf blight disease of Allram spp. caused by Botrytis and Botryotinia fungi.

Abstract

A description is given of a Botrytis-like fungus affecting onion leaves in the Osaka and Hyogo prefectures, causing water-soaked, elongated lesions which become covered with conidia in humid weather and black sclerotia under drier conditions. The fungus is considered to be identical with B. byssoidea in the conidial state, and with Sclerotinia allii in the ascigerous one, and is renamed Botryotinia allii (Sawada) Yamamoto.
