Abstract:
The present study was on pathogenicity, morphology and identification of Claviceps fusiformis which responsible for ergot disease of pearl millet and observed most favorable stage of panicle emerged at which highest disease was observed. The disease was found to be very severe in all pearl millet growing areas causing heavy destruction. The main aim of this study clearly demonstrated that C. fusiformis is a primary pathogen in pearl millet, causing ergot disease. Isolates of C. fusiformis were collected from ergot infected panicle (at honey dew stage) of pearl millet in the fields around Jobner, Jaipur. The pathogen was isolated from sample on PDA media in Petri plate and make a mass multiplication for pathogenicity test. Inoculated the conidial suspension on healty plant and symptoms test morphology of pathogen are identified according to Thakur and King 1988 and observed that highest PDI (53.1 per cent) at 75 per cent panicle emerged followed by 42.6 per cent PDI at 50 per cent panicle emerged than 35.88 per cent PDI at 25 per cent panicle emerged.
