Abstract:
A survey study was carried out to determine the prevalence and incidence of basal rot disease of onion in Maharashtra from major onion growing regions. Four districts viz., Nashik, Pune, Solapur and Ahmednagar of Western Maharashtra were surveyed. The survey sought to determine the crop stage at which the symptoms appear, disease incidence and yield loss in onion crop. During survey basal rot of onion was found as an important fungal disease in majority of onion fields. The onion basal rot disease is prevalent in all four districts surveyed. Nashik district recorded maximum incidence followed by Pune and Ahmednagar districts whereas minimum incidence was observed in Solapur district. The level of infection was found to be influenced by climatic conditions such as temperature, rainfall and relative humidity.
