Assessment of Root Rot Disease in Green Gram (Vigna radiata L.) Caused by Rhizoctonia bataticola Under Controlled Pot Culture Conditions

Root rot caused by Rhizoctonia bataticola is a major constraint in green gram (Vigna radiata L.) cultivation, especially under high temperature and low soil moisture. This study assessed the severity of root rot and the associated impact on plant growth under pot culture. Green gram plants (variety CO 8) were grown in nine pots under three treatments: uninoculated control, low, and high inoculum doses of R. bataticola. Disease incidence, severity, plant height, biomass, and yield were measured. Results showed that higher inoculum loads significantly increased disease severity and reduced growth and yield parameters. This study reinforces the destructive potential of R. bataticola in mungbean and highlights the need for integrated disease management strategies, including host resistance and soil health maintenance.
