Sonebhadra district is one of the less studied regions of India for its ethnobotanical values. The present paper synthesizes the first report related to the documentation of ethnomedicinal plants of Sonebhadra district and their infection by foliar fungi. Ethnobotanical data were collected using semi-structured interviews and field observations. Correct identity of the plants was done with the help of relevant flora. Fungal organisms were identified on morphotaxonomic bases. The use of 143 medicinal plants belonging to 56 angiospermic families, by the tribal communities of Sonebhadra district has been documented. Out of 143 medicinal plants, 31 were found infected by different species of foliar fungi viz. Pseudocercopsora, Alternaria, Cercospora, Passalora, Corynespora, Mycovellosiella, Veronia and Dreschslera. Documentation of indigenous knowledge used for cure of different diseases by the tribes of the area can be used as basis for developing management plans for conservation and sustainable use of ethnomedicinal plants of the area. The report on foliar fungi infecting medicinal plants may draw attention of pharmaceutical firms and responsible sectors for proper care of the traditionally used medicinal wealth of the area.
Key words: Ethnobotanical, medicinal plants, indigenous knowledge, foliar fungi, Sonebhadra district.
