In-vitro Effect Evaluation of Botanicals against Sclerotinia sclerotiorum (Lib.) De Bary, Caused Stem Rot Disease in Rapeseed-Mustard

Mustard (Brassica juncea (L.) de Bary) is one of the most important oilseed crops in India. It’s cultivated in various states of India and around the world. It is grown as a traditionally crop (Pure crop) as well as intercrop (mixed crop) in marginal and sub-marginal soils in the some part of eastern, northern and north western region of the Indian states. Its favourable climate is cool and moist weather situation during the period of winter season, for its better growth and as well as its productivity. Many biotic and abiotic factors are involved to decrease the yield of rapeseed- mustard in every year. Among them, Stem rot (Sclerotinia sclerotiorum) disease is the most destructive fungal disease that causes maximum damage in rapeseed- mustard. The first symptom of Sclerotinia stem rot was seen as water soaked patches on leaves and on root of the plant at its flowering stage. Madhya Pradesh is an important rapeseed mustard producing state of India contributing more than 10 per cent of the total production in the country.
