Abstract
The incidence and survey of different diseases were worked out during 2009-10 and 2010-11 under natural disease pressure and observed that leaf mosaic (Begomovirus) was more severe followed by foot and stem rot (Phytophthora parasitica). The results indicated that over all incidence of leaf mosaic ranged from 65.66% (Bahraich) to 68.72% (Balrampur) whereas foot and stem rot ranged from 13.60% (Shravasti) to 16.36% (Gonda).
