Abstract:
Sclerotium delphinii (syn. Sclerotium rolfsii var. delphinii) is a serious pathogen infecting plants in the genus Ajuga, Arachis, Hosta, Iris, Malus and many additional herbaceous ornamental species but there has been no report of this pathogen infecting cotton. Plants infected with S. delphinii were first noticed in the fields of Wardha, India, during 2011- 2012.. The causal agent was isolated in PDA medium and identified by sequencing the ITS region and its pathogenicity was determined by fulfilling Koch’s postulates.
