dc.description.abstractThis study was conducted in finding out the invitro effects of aqueous and methanol extracts of Moringa oleifera (Lam) aerial parts on fungi isolated from some selected varieties of Sorghum bicolor L. Different varieties of Sorghum bicolor L. namely Samsorg 17, Samsorg 40, Samsorg 42, Samsorg 43 were obtained from Plant Science Department IAR, and a local land race Kaura was collected from Sabon Gari Market in Zaria. Five different fungi namely AspergillusflavusLink,Aspergillus niger VanTieghem,Fusarium oxysporum Schlecht, Rhizopus stolonifer (Ehrenb.)Lind and Phoma herbarum Sacc were isolated from the grains. These were isolated on both potato dextrose agar(PDA) and Saboraud‟s dextrose agar(SDA) using the agar plate method. The predominance of Aspergillusspp. indicate that they possibly act as pioneer organisms in the seed borne infection while the presence of other isolates show that there is possible succession of fungi in the seed borne infection. On invitro culture of these organisms in PDA amended with varying concentrations of MoringaoleiferaLam extracts (Aqueous and Methanol) from the leaves, seeds and stem bark using the radial growth method, extract from the leaves were found to be more effective than the other two in the mycelia growth inhibition of the isolated fungi. Growth of these fungi inhibits more in the presence of higher concentrations as compared to lower concentrations of extract. However the cumulative effects of these extracts were found to vary with concentration, plant parts, pathogen as well as type of solvent used for the extraction.en_US
