Symptoms of Fusarium stalk rot include rotting at roots, crown and lower internodes. Fusarium culmorum is a ubiquitous soil-borne fungus able to cause foot and root rot and Fusarium head blight on different small-grain cereals, in particular wheat and barley. phaseoli), Rhizoctonia root and pod rots (Rhizoctonia solani), and Pythium damping off, wilt and pod rot (various Pythium species).
