Abstract:
Chickpea is one of the major legume crops cultivated in India. Sclerotinia rot or white rot of chickpea incited by Sclerotinia sclerotiorum (Lib.) de Bary has become a serious problem in recent years in major chickpea growing areas of Rajasthan and other chickpea growing parts of India. A roving survey was conducted during Rabi 2016-17 and 2017-18 in foremost chickpea growing districts of Rajasthan exposed that Sclerotinia rot was the main problem in Sri Ganganagar (19.95%), Hanumangarh (19.04%), Kota (18.55%), Sawaimadhopur (17.84%) and Bikaner (16.53%) districts. The maximum disease incidence was observed on the collar region, stem, and foliage leading to mortality of the plants. With the progress of the disease, a white web of fungal mycelium and Sclerotia were seen on disease-infected parts giving its typical diagnostic symptoms. The diseased plants were spotted in the field during February and March.
