Pythium stalk rot: Pythium aphanidermatum
Symptoms |
-
Usually the basal internodes become soft, dark brown water soaked, causing the plants lodge.

Damaged internodes commonly twist before the plants lodge. Diseased plants can remain alive until all vascular bundles become affected.
-
Isolations in culture media are necessary to differentiate Pythium from Erwinia stalk rots.
