Abstract
Summary A die-back disease of onion foliage characterized by pale spotting and death of the leaves from the tip downwards, associated with Botrytis infection, was investigated during 1941–2. Of three species of Botrytis isolated from diseased leaves, B. squamosa , recorded for the first time in this country, was the predominant organism. The other fungi were B. cinerea and an unidentified form. Infection was limited to autumn and winter and plants usually grew away healthy in spring and summer. The disease is probably an example of facultative parasitism.
