Occurrence of Botrytis Fabæ Sardina in England

Abstract

The Chocolate Spot disease of broad and field beans is well known and widespread throughout Great Britain, and causes considerable loss of crop when there is high humidity and much rain at the time of flowering. The cause of the disease, in the eastern counties at least, was shown by A. R. Wilson¹, in 1937, to be the common fungus Botrytis cinerea Fr. He proved, however, that similar symptoms could be brought about by other Botrytis species, such as B. Tulipæ Lind.
