PCR based detection of bacterial wilt pathogen, Ralstonia solanacearum in ginger rhizomes and soil collected from bacterial wilt affected field

Abstract

PCR based detection of bacterial wilt pathogen in rhizomes and soil has been described. Bacterial wilt pathogen, Ralstonia solanacearum was PCR detected in apparently healthy rhizomes and soil collected from fields in endemic area. The protocol offers an indexing method for bacterial wilt pathogen in seed rhizomes and soil. The study emphasizes the need for imposition of restriction in the movement of such rhizomes from endemic locations to non traditional areas.
