Aspergillus niger and Rhizopus oryzae are two common pathogens of post harvest fruits diseases in Mkpat Enin Local Government Area of Akwa Ibom State. Traditional control measures of these pathogens have emphasized use of chemicals with high environmental toxicity. The search for alternative control methods using local plant products which are environmentally friendly is therefore necessary. Thus, antifungal properties of Mimosa pudica, Phyllanthus amarus, Emilia sonchifolia, Bryophyllum pinnatum and Amaranthus hybridus leave extracts were investigated using disk diffusion method while screening for bioactive compounds was carried out using standard phytochemical procedures. Antifungal activities were tested against the two pathogens at 2%, 4%, 6%, 7% and 10% concentrations. All extracts indicated significant growth inhibition on the two pathogens with 10% recording the highest. Phytochemical screening showed the presence of tannin in all the plant extracts tested while saponin was found in all except B. pinnatum extract. Flavonoids were present in all but B. pinnatum extracts. Leave extracts of the tested plants can be explored as potential fruit disease control natural products which are less hazardous.
