Abstract

A Survey was being conducted in ten districts of Uttar Pradesh namely Ghazipur, Balia, Mirzapur, Mau, Azamgargh, Jaunpur, Varanasi, Gorakhpur, Deveria and Basti which were carried out during Rabi 2018-2019 and 2019-2020 to know the incidence and severity of foliar blight especially spot blotch disease of wheat caused by Bipolaris sorokiniana. Survey work was done in first and third week of March during both the years. As it is well known that the month of March is suitable period for survey work because during this month humidity and temperature favors the foliar blight incidence. The highest incidence of foliar blight was noted in district Gazipur (75.52 per cent) followed by Balia (73.65 per cent), Mirzapur (72.67 per cent), Mau (68.23 per cent), Azamgarh (60.38 per cent), Jaunpur (59.60 per cent), Vanarasi (58.18 per cent), Gorakhpur (57.87 per cent), Deveria (56.74 per cent) and Basti (56.55 per cent) respectively during first year (2018-19) of study.
