Keywords: Aqueous plant extract, comparative effect, mycelial growth, sporulation, staple food, storage fungi.



Abstract - This study investigated in-vitro the control of fungal species found associated with the storage of four staple food crops at Ibadan in the humid forest of southern Nigeria using some indigenous plant extracts. Aspergillus flavus, Aspergillus niger, Penicillium expansum and Rhizopus stolonifer were found associated with the spoilage of horticultural crops in storage. The results of the investigation revealed that, Acalypha ciliata, Aloe vera, Azadirachta indica and Vernonia amygdalina were effective in the inhibition of Aspergillus flavus and Penicillium expansum. Annona squamosa effectively inhibited the mycelial growth and sporulation of Aspergillus niger and Rhizopus stolonifer. Aloe vera extract was equally effective in the reduction of mycelial growth and sporulation of Aspergillus niger. In the overall, a significant reduction in mycelial growth and sporulation of the pathogens was found associated with treatment with most of the plant extract tested.
