Department of Plant Pathology, COA, Gwalior, Madhya Pradesh, India A potential menace: Stem rot in mustard Omprakash Bharti, RK Pandey, Reeti Singh and RK Singh Abstract Stem rot is a most serious disease of rapeseed mustard. Earlier, it was considered as a minor disease and now, it has become a serious problem in recent years. Northern region of Madhya Pradesh jointly contributes >60% production of the rapeseed mustard. In search of the new botanicals, biological agents, animal byproducts and chemicals may lead to integrated management of the disease with no fluctuation of the environment. With view of resistance, there was no proven resistance in the brassica genotypes against the disease. Stem rot is a polyphagous and soil born nature, hence, the sclerotia can survival upto 5 years in the soil. The identified of the new genes in rapeseed mustard against this disease though advanced biotechnological approaches. With the view of the above points more need to do work in future on the mustard crop against Stem rot. Keywords: Stem rot, mustard, chemical, survey, isolates, RAPD Introduction Stem rot is one of the most serious disease and causes damage to oilseed Brassica. Earlier, it was considered as minor disease and now, it has become a serious problem in recent years. Stem rot set as a key in foot of the most mustard growing area of northern region of Madhya Pradesh. Disease incidence was recorded upto 60 per cent and in fields where disease incidence was upto 70 per cent, 40-50 per cent seed yield loss was recorded Fig-1. With the view of the Resistance in mustard genotypes, none of the cultivars were found free from infection of the disease till now. The overview article or survey of article is prepared on available related aspects work done on the Stem rot (Sclerotinia sclerotiorum) in rapeseed mustard crop has been reviewed by earlier researcher and upto present status of work. The available literature on the concerned topic is briefly reviewed as under: History and geographical distribution Shaw and Ajrekar (1915) [71] first recorded that the occurrence of Sclerotinia blight on rapeseed and mustard has been made from India and later the disease has been observed in severe from in other countries like Australia (Holtzhausen and Knox Davies, 1974) [33] Brazil (Neto,1955) [52] . Canada (Duczek and Morral, 1971; Plat ford and Bernier, 1975; Davidson, 1977) [26, 21] . China (Yang, 1959) [88] Denmark (Buchwald 1947) [11] England (Sansford,1995) [69] , Finland (Jamalainen 1954) [35] , France (Brun et al. 1981; Hims,1979) [10, 32] , Germany (Klemm,1938; Kirchner and Pluschkell,1979; Kruger1976) [42, 41, 45] India (Shaw and Ajrekar, 1915; Roy and Saikia, 1976) [71, 67] , Israel (Palti,1959) [57] , Italy (Zazzerini and Tosi, 1985) [89] , Mexico (Ponce and Mendoza 1983) [59] , New South Wales (Loof, 1959) [59] , Nepal (Shreshtha, 1986), New Zealand (Wong and Willets,1975) [85] , Peru (Bazan and Segura, 1952) [6] , South Africa (Holtzhausen and Knox Davies, 1974) [33] Swedan (Djurle,1982) [25] and United Kingdom (Hims, 1979) [32] . Boland and Hall (1994) [9] reported that Sclerotinia sclerotiorum (Lib.) de Bary capable to infect over 408 plant species under 75 families. Purdy (1955) [62] concluded that the synonymy with S. sclerotiorum several species described from various hosts and locations since 1955 no new information has appeared that would justify alternate of my opinion. Sansford (1995) [69] reported that the stem rot is world-wide problem to mustard cultivation. Vasudeva (1958) [82] reported that the term white blight has been used as a common name of the disease incited by S. sclerotiorum. However the disease has also been named as white rot (Rai and Dhawan, 1976; Rai et al.1974) [64, 65] White blight (Roy and Saikia, 1976) [67] and stem canker (Klemm, 1938; Kruger et al. 1981) [42] , based on the specific symptoms produced. The different isolates of Sclerotinia sclerotiorum of infected B. juncea in
