Abstract
White rust caused by Albugo candida has been reported to be most wide spread and destructive fungal disease of rapeseed-mustard. An extensive field survey was carried out during rabi season 2020-21 at farmer’s fields in total five villages of Jalaun district in Bundelkhand region. The observation of disease was taken during the month of January to February from pre- flowering to pod formation/maturity stage of the crop. The disease incidence and severity in these surveyed villages ranged from 31.45 to 54.70 per cent and 28.57 to 51.21 per cent, with an overall average of 38.75 per cent & 36.21 per cent, respectively. But significantly maximum disease incidence and severity was recorded in Goran village (54.70 and 51.21 per cent) followed by Kahata village (39.87 and 37.10 per cent), respectively. While as, the minimum percent incidence and severity was observed in Jaisari Kalan (31.45 and 28.57 per cent) followed by Timron (33.77 and 31.83 per cent).
