Prevalence, Incidence and Management of Alternaria Blight of Rape-Seed and Mustard (Brassica juncea L) through Resistance and Integrated Approach

Rapeseed-mustard (Brassica juncea L) is an economically important oilseed crop of the world. In India, rapeseed-mustard is grown over in diverse agrolargest indigenous oilseed crop which contributing 32 per cent of total oilseed production in India climatic conditions ranging from north-eastern/northwestern hills to down south. It is second. Out of 63.09 million tonnes of estimated rapeseedmustard produced over 37.00 million hectares acreage with the productivity of 1850 kg/ha in the world, in India rapeseed-mustard is cultivated in an area of 6.7 million hectares with a production of 7.90 million tonnes with productivity of 1188 kg/ha (Anonymous, 2014). In Jammu & Kashmir state, rapeseed mustard is cultivated in 0.059 million hectares leading to production of 0.040 million tonnes with a productivity of 682kg/ha (Anonymous, 2015).
