Abstract: A survey for the incidence of post-harvest rot of fungal pathogens of Irish Potato was carried out in four locations within Biu Local Government Area of Borno State,the sample size of 80 tubers / market (320) was taken and the average percentage incidence of rot was 9.06%, the highest rot was in Mirnga Market (13.25%) while the lowest was in Hospital Market (6.25%). Four fungal pathogens. were associated with this rot (Aspergillus flavus, Thielavia terricola, Rhizopus stolonifer and Scopulariopsis brevicaulis) the most frequent occurring was Rhizopus stolonifer while the least frequently occurring was Aspergillus flavus. Thielavia terricola was most pathogenic with rot lesion size of 14.11mm. In vitro test with garlic oil, neem seed oil and tridax leaf ash showed that the test substances were significantly effective (p=0.0001). Tridax leaf ash had the highest inhibition of 18.50 while neem seed oil and garlic oil had the least inhibition rate of 20.16 and 24.18 respectively. In vivo test with garlic oil, neem seed oil and tridax leaf ash at p=0.0001showed that the test substances were significantly(0.0001) effective. Tridax leaf ash had the highest inhibition of 3.13. while Garlic oil and neem seed oil had the least inhibition rate of 4.02 and 4.19 respectively. It is therefore suggested that more research should be conducted on the ash with garlic oil and neem seed oil and their effects on the same pathogens or similar ones.
