- Title
ROOT ROT OF CROCUS CAUSED BY PYTHIUM ULTIMUM.
- Authors
Tomlinson, J. A.
- Abstract
This article focuses on the root rot of crocus caused by Pythium ultimum. In November 1950, some young, well-sprouted crocus corms had been forced in a greenhouse for early flowering but, after a good start, had shown arrested development. The corms themselves were healthy but many of the roots had been cut short by a bright orange-colored rot and were dull and water-soaked. Isolated orange-colored lesions, up to a quarter of an inch in length, were also present on many roots. Abundant aseptate mycelium and oospores were found in the affected areas. The fungus was isolated in pure culture and identified as Pythium ultimum Trow.
