Abstract:
Chickpea (Cicer arietinum L.) is one of the third most important legumes crops after dry beans and peas grown across the world. Collar rot caused by Sclerotium rolfsii is a major disease of chickpea in Central India that may cause 55 to 95% seedling mortality. An intensive roving survey was conducted in 2021-22 and 2022-23 during rabi cropping season to determine the prevalence and incidence of the Collar rot of Chickpea caused by Sclerotium rolfsii in the Bundelkhand region of Uttar Pradesh. Incidence of Collar rot disease was detected in early stages of crop (4-5 week after sowing) development with geotagging of the field. Collar rot is commonly seen in the high moist condition. The location of the field was taken through GPS camera, and each field three spots were randomly selected using quadrate (1 m²). Collar rot disease was found in all of the surveyed blocks. Highest mean disease incidence of 14.5% was recorded in Lodhipur village of Muskara block followed by 14.5% in Kakrau village of Kurara block. Lowest mean incidence 4.5% was recorded in Chakrauli village of Karwi block. The overall mean disease incidence highest in Hamirpur district 10.06% followed by Mahoba district 10.02%. Thus, the incidence of collar rot in chickpea ranged from 4.5 to 14.5%, which was quite high to causing seedling mortality and significant crop losses.
