The Most Important Fungal Diseases Associated with Some Useful Medicinal Plants

Plants are a major source of active ingredients and are for that fact used to treat many diseases such as fungal infections. The objective of this study was to identify the plants used in traditional medicine to treat fungal diseases in the prefecture of Sotouboua. An ethnobotanical survey was conducted among healers, elderly and knowledgeable villagers. A semi structured questionnaire and pictures showing common and easily recognizable fungal infection symptoms were used to support a live interview. During this study, 37 plant species belonging to 20 families have been identified. Fabaceae were the most represented family (7 species). The most used parts were leaves (43, 24%) followed by the roots (18, 91%). The decoction is the preferred method of preparation while the oral route is the main route of administration. Sotouboua prefecture in Togo has significant plant biodiversity that is used by dwellers in the management of fungal diseases.

A season wise survey was conducted on the fungal diseases of some important cultivated medicinal plants in two consecutive years 2014 and 2015 in the northern region of Bangladesh. Eleven fungal diseases namely root rot (Fusarium solani) and leaf blight (Alternaria alternata) of Ashwagandha, leaf spot (Curvularia lunata) and collar rot (Fusarium oxysporium) of Alovera, powdery mildew (Erysiphe sp.) and root rot (Fusarium oxysporium) of Tulsi, collar rot (Fusarium oxysporium) and leaf spot (Collettotrichum gloeosporioides) of Kalmegh, tuberous rot (Fusarium solani) and stem rot (Fusarium oxysporium) of Satamuli, and root rot (Fusarium solani) of Basak were recorded. Most of the diseases were found in the rainy season’s comparative to other seasons. Among all the above-mentioned diseases, the powdery mildew (Erysiphe sp.) of Tulsi was found mainly in winter season. With the spreading of these fungal diseases on medicinal plants could be a set back to the industry associated with the formulation of its medicinal products. Therefore, this work may encourage other researchers to study these diseases further for development of proper management. SAARC J. Agri., 17(2): 197-212 (2019)

BACKGROUND: Plants remain the natural sources of efficacious phytonutrients with beneficial assets to mankind against microbial disorders. Diverse folklores have reported the roles of medicinal plants in the remedies of various disorders in man and animals. Metabolites and pesticides from the plant origin are considered better alternatives due to favorable environmental impact as compared to the synthetic counterparts. Significant economic losses and hindrance of global papaya production are due to fungal diseases. Phytochemicals have made medicinal plants become sources of environmentally friendly alternative antimicrobials. AIM: This study aimed at assessing the antifungal activity of leaf extracts of Moringa oleifera against phytopathogenic fungi isolated from Carica papaya. METHODS: n-Hexane, ethyl acetate, ethanol, methanol, and aqueous extracts of M. oleifera leaves were evaluated for their antifungal properties. Agar well-diffusion method was implemented for in vitro screening, minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the extract types against fungal species of Aspergillus, Penicillium, Rhizopus, and Trichoderma. RESULTS: All the extracts evaluated inhibited fungal growth to some degree, with the aqueous extract exhibiting more inhibitory activities than the organic extracts. There was significant inhibition of fungal development by the tested plant extracts at different concentrations. MIC of the extracts was 15.625 mg/ml while the MFC values ranged between 15.625 and 31.25. In this work, the antifungal activity of M. oleifera was found to be equal or higher than commercially available fungicide, ketoconazole. CONCLUSION: The results of this study indicate that foliole extracts of M. oleifera have potential for use as biofungicides for plant protection against fungal diseases.
