Abstract

The continued persistence of Botryodiplodia theobromae Pat., a yam-rot pathogen, from one storage period to another was investigated in the leaves, stem fragments and in the tuber of the host. The fungus survived in the stem for six months in the tubers for over eight months, and in the leaves for only three months. It was also viable for at least ten months in sterile soil samples inoculated with infected yam tuber pieces which served as food bases. The fungus survived in yam tubers as modified hyphae in form of chlamydospores.
