Rhizoctonia bataticola: A threatening pathogen causing dry root rot of chickpea (Cicer arietinum L.) under changing climate conditions: An extended review

Abstract

Dry root rot, caused by Rhizoctonia bataticola (syn. Macrophomina phaseolina), is one of the most destructive soil-borne diseases affecting chickpea cultivation in semi-arid and arid zones. The pathogen thrives in conditions of high temperature and low soil moisture, both of which are being amplified due to global climate change. This extended review compiles information on the biology, epidemiology, environmental interactions, pathogenic variability, host resistance, and integrated management strategies of this pathogen. Research from across India confirms that Rhizoctonia bataticola is a highly adaptable pathogen exhibiting significant variability and virulence across regions. Integrated management combining host resistance, seed treatment, fungicide application, and biological control offers the best sustainable approach to mitigating its threat.
