Antifungal, Telfaira occidentalis, Fungi, Carica papaya, Phytochemicals


Infused within plants are potent phytochemicals with beneficial activities to mankind which includes the management and treatment of microbial infections. Fungal diseases result in significant economic losses and hindrance of global papaya production. Phytochemicals have made medicinal plants become sources of environmentally friendly alternative antimicrobials. This study aimed at evaluating the antifungal activity of leaf extracts of Telfeira occidentalis against phytopathogenic fungi isolated from Carica papaya. Ethyl acetate, n-Hexane, ethanol, methanol and aqueous extracts of Telfeira occidentalis leaves were evaluated for their antimicrobial properties. Agar-well diffusion method was employed for in vitro screening, minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the extract types against test fungal species of Aspergillus, Penicillium, Rhizopus and Trichoderma.
All the extracts evaluated inhibited fungal growth to some degree, with the aqueous extract exhibiting more inhibitory activities than the organic extracts. MIC and MFC values of the extracts ranged between 15.625 to 31.25 and 62.5 to 125 mg/mL, respectively. The antifungal activity of T. occidentalis was found to be equal or higher than commercially available fungicide, ketoconazole. The results of this study indicate that leaf extracts of T. occidentalis has potential for use as bio-fungicides for plant protection against fungal diseases.
