Abstract :
Molds are the chief pathogens of stored corms
and as such cause huge post-harvest and economic losses to
cocoyam farmers in Nigeria. This research was aimed at
isolating and identifying molds associated with post-harvest
loss of Xanthosoma sagittifolium. The spoilage molds
identified were Aspergillus tamari, Aspergillus niger,
Fusarium oxysporium, Fusarium solani and Mucor
circinelloides. These isolates were subjected to pathogenicity
tests using fresh healthy tubers in order to confirm their
ability to elicit same spoilage symptoms in healthy corms. 30
test corms were used and were divided into groups A, B, C,
D, E and F. Weights, rot types and percentage rot severity
were monitored during the research. Dry rot had the highest
value of 75%, soft rot had 25%; these brought to the
summary of the fact that these molds are associated with the
spoilage of Xanthosoma sagittifolium during storage.
