Vigna mungo is a plant having good nutritional values and medicinal importance and it plays a significant role in human nutrition. Many recent studies have been conducted on the nutritional quality of V. mungo (Hussain et al., 2010; Blessing and Gregory, 2010). The studies suggest that this bean is a good source of protein, carbohydrate and minerals (Agugo and Onimawo, 2009; Suneja et al., 2011). Its medicinal uses are reported in different traditions of medicine such as Ayurveda and Unani. It is mostly used for therapeutic purposes and is known to posses antihypertensive and antidiabetic properties (Lin et al., Gary, 2006; Yang et al. 2008). This plant is severely attacked by various fungal pathogens. A periodical survey was conducted during the month of November-2012 to March-2013 to collect infected leaves of V. mungo from five different locations of Raipur district viz. Indira Gandhi Krishi Vishvavidyalaya, Raipur, two villages Jora and Bhatagaon, farm house and kitchen garden of Kushalpur Raipur. Severe brown spots were observed on the plants of Vigna mungo for phytopathological investigation. Total two fungal pathogens have been isolated from the leaves of the crop. Fusarium semitectum (FS). Corynespora cassiicola (CC) were isolated from leaves showing reddish brown, circular, regular and necrotic spots. Leaves were severely damaged in both symptoms and both species of Fusarium semitectum (FS Corynespora cassiicola showed severe degree of infection and diseases intensities. Pathogenicity test was proved by Koch's postulate. Conidial size was measured using micrometry. Suitable control and protective measures should be taken into account to prevent this major kharif crop from the microbial invasion so as to get a healthy crop of immense nutritive value.
