Sclerotinia stem rot: A potential threats to mustard cultivation in northern Madhya Pradesh

Sclerotinia sclerotiorum (Lib) De Bary, is the causal fungus of Sclerotinia stem rots in Mustard. This study was aim to survey the Sclerotinia stem rot affected area. Keeping in view the importance of the disease a well-planned block wise field survey of major mustard growing districts viz., Morena, Bhind, Gwalior, Sheopur and Datia were carried out during January-March 2015. The disease is emerging as a serious threat to mustard cultivation. While, the surveyed districts taken all blocks from three villages and from each village taken five field randomly selected. Surveyed village of blocks heavy disease incidence recorded in Morena (11.52%), Bhind (13.48%) and Gwalior (6.33%) were identified a shot spots but in Sheopur (2.81%) and Datia (5.00%) were recorded fewer incidences as compare to highly incidence districts. At present study of field surveys indicated that Sclerotinia stem rot has set its foot as a key position among mustard disease in Northern region of Madhya Pradesh. Sclerotinia stem rot incidence was increasing gradually year after year and emerging as a serious threat to mustard crop. The disease appears regularly become mild to severe forms in remains different Rapeseed-Mustard growing areas of Madhya Pradesh. The low incidence of Sclerotinia stem rot disease was adopting (Mustard + Wheat) cropping pattern adopted, where the sandy loam alluvial soil, while, where, adopting (Mustard + Pea), (Mustard + Chickpea) and mono crop (only mustard) grown areas were found high incidence of this disease and soil was light black to black cottony soil with less drainage facility. This disease most found in early sowing farmers’ field but there was not found in late shown fields. Hence, these above points may help to make strong strategies for managing this disease with compatible integrated disease management practices.
