Sclerotinia stem rot of Indian mustard (Brassica juncea) caused by Sclerotinia sclerotiorum (Lib.) de Bary is one of the imminent diseases of Rape seed-mustard. A study was conducted to ascertain the epidemiological factors involved in disease development. As soon as the disease appeared in field, the number of infected plant was recorded. Subsequently the disease incidence was recorded fortnightly and it was correlated with atmospheric parameters. The data on the maximum and minimum temperature, relative humidity, rainfall and per cent disease incidence in each phase were recorded from the observatory of the University and correlated with the most favourable temperature, relative humidity and rain fall for the disease development. It was perceived from the observations that the disease continued to progress in field at a low temperature causing massive damage to the crop. The disease continued to progress till the temperature reached 26.90C (maximum temperature) and 14.60C (minimum temperature) in 2014-15.
