Morphological identification of weevil and fungal pathogen associated with sweet potato tuber during storage
Sweet potato is a perishable food crop that is prone to weevil and fungal infection. Development of diseases due to fungal infection will lower its quality, reduce marketable price and sometimes the tubers are unable to sell. Crop losses due to diseases not only have bad implication to farmers, bu...

| description | Sweet potato is a perishable food crop that is prone to weevil and fungal infection. Development of diseases due to fungal
infection will lower its quality, reduce marketable price and sometimes the tubers are unable to sell. Crop losses due to
diseases not only have bad implication to farmers, but also give threat to global food production and food security. This
study was conducted to identify and document the insect and fungal pathogens associated with sweet potato diseases. For
this purpose, infected tubers were collected, incubated and isolated before conducting the pathogenicity test. Ninety sweet
potato weevils, Cylas formicarius had emerged and caused extensive damaged to the tuber. Following the sweet potato
weevil infestation, four fungal isolates were successfully identified as Fusarium oxysporum (one isolate), Penicillium sp.
(one isolate) and Aspergillus sp. (two isolates). All these isolates were pathogenic to sweet potato tubers with different level
of diseases severity, ranged from 33.33% to 42.59%. Identification of weevil and fungal pathogen associated with sweet
potato diseases is important to help in control strategy to avoid epidemic diseases that may cause loss of economic return.
Besides that, farmers should applied integrated pest management control for continuous production of good quality sweet
potato tuber. |
