Stem rot or white mould of mustard is becoming an emerging threat for mustard cultivation in the Northern part of Bangladesh. Stem rot of sesame has been identified as a new disease in Bangladesh caused by Colletotrichum dematium. Foot and stem rot of groundnut is becoming major disease with the change of climatic factor. Leaf spot of groundnut and purple blotch of onion were found to be severe in the cropping season 2010-2011 at the surveyed locations
