Abstract : Citrus is one of the most widely grown plants in the world; however, it is affected by many types of fruit rot diseases after harvesting. Orange fruits showing rot symptoms that are displayed for sale local market were collected and examined for the presence of the pathogenic fungi. Three species of fungi Alternaria alternata, Aspergillus niger, and Penicilllium digitatum were found to be associated with fruit rots of orange. P. digitatum was the most frequently isolated and A. niger was the least isolated 63.9% and 11.1% respectively. All isolated fungi were pathogenic to the different fruits when pathogenicity tests were carried out. They produced same symptoms and signs as observed in the original spoilt orange fruits before isolation. All fungal isolates were able to re-infect the healthy citrus fruits with the exception of Alternaria which was weakly to grow and produce spoilage condition on the inoculated healthy orange fruits after five days. P. digitatum as the most pathogenic inducing a rot diameter of 2.4cm within 5 days of inoculation.
