Abstract
The presence of fungi in oranges poses a significant risk to public health, impacting global economies and the
well-being of both humans and animals. To effectively address this problem, it is important to identify the specific
types of fungi to address this concern effectively. This study was aimed at isolating and characterizing fungal
species associated with rotten sweet oranges (Citrus sinensis L.) in the University of Ilorin using phenotypic
characterization and molecular tools. A total of five orange fruits were collected from different trees at the Unilorin
botanical garden and immediately transported to the Biology laboratory, University of Ilorin. The rotten part of
the fruits was cut out, surface-sterilized, and then inoculated onto potato dextrose agar. Aspergillus flavus,
Aspergillus niger and Rhizopus arrhizus were the fungal isolated and identified. The identification of these
pathogens is crucial for implementing effective post-harvest management measures. This will aid in eliminating
the pathogens from sweet orange fruits during post-harvest handling, reduces spoilage and extending their shelf
life.
