Roving Survey of Root Rot Disease of Pea Caused by Fusarium solani f. sp. pisi in Rajasthan, India

Abstract

Pea, a vegetable crop grown in cool regions of the world. It has a great economic importance in India. The survey conducted in the major pea-growing regions of Rajasthan during the Rabi season of 2021-22 highlighted root rot as a significant issue caused by Fusarium solani f. sp. pisi. The study covered areas in Jaipur, Sikar, Nagaur, Ajmer, and Alwar regions. To assess disease incidence, researchers randomly selected 25 square meter areas at four spots in each field, totaling 100 square meters per field. In each village, fields were chosen, and plants displaying typical root rot symptoms were collected for further analysis. Upon examination, an average disease incidence of 23.68 percent was recorded across the surveyed districts. The highest incidence was observed in Jaipur at 30.85 percent, while the lowest was in Nagaur at 16.91 percent. To further understand the pathogen responsible for root rot, samples were collected and brought to the laboratory for isolation. This comprehensive survey provides valuable insights into the prevalence of root rot in pea crops across different regions of Rajasthan, aiding in the development of effective management strategies.
