Root and storage-rot disease of cocoyam in Nigeria

1981

Okeke, G.C. (National Root Crops Research Institute, Umudike, Umuahia (Nigeria))

Symptoms and some aspects of etiology of cocoyam root and storage rot were studied. Botryodiplodia theobromae, Fusarium solani, F. moniliforme, and Sclerotium rolfsii were found to be in constant association with storage rot of cocoyam in Nigeria. Field symptoms of the disease included extensive root decay, leaf chlorosis followed by necrosis and shriveling of affected parts, and finally premature death of the aerial portions of the plant. Poor production of cormels and reduced corm sizes were other field symptoms of the disease.
