Summary
The blackgram (Vigna mungo) crop in Uttar Pradesh has been found to suffer from a new fast spreading web-blight disease caused by an aerial strain of Thanatephorus cucumeris. The pathogen has a wide host range but is specific to aerial parts. The pathogen produces sclerotia in plenty on the affected parts and fallen leaves. Basidiospores are formed in nature on healthy tissues adjacent to lesions. Fruiting of the pathogen in vitro was successfully induced by making well nourished fungus grown on a less nutritive substratum. The modes of primary infection and secondary spread and possible methods of controlling the disease are discussed. [AS]
