Abstract:
The rhizome rot disease is the most destructive disease of ginger in India which reduces its economic and commercial value. To determine the causal agents of the disease fungal isolation was performed using PDA medium. The different fungal pathogens viz. Pythium aphanidermatum, Fusarium oxysporum f.sp zingiberi and Sclerotium rolfsii were isolated from infected rhizomes. These pathogens were identified based on their cultural, morphological and pathological characteristics and confirmed by microscopic observations. Pathogenicity of these pathogens were proved by applying various inoculation techniques like soil inoculation and rhizome inoculation. All the isolated pathogens were found to be pathogenic. While, P. aphanidermatum showed early mortality than other pathogens.
