Abstract

Ralstonia solanacearum is a soil-borne gram-negative bacterium that causes bacterial wilt disease in more than 250 plant species belonging to botanical families. Over the last decades, R. solanacearum infestation has increasingly been observed in temperate climate regions. Three R. solanacearum isolates have been obtained from wilt infected brinjal (eggplant) plant from Mizoram, North East India. Different morphological and biochemical testes confirmed the typical characteristic features of bacterial wilt pathogen. Amplification of 280bp DNA fragment in PCR with (759,760) egl gene primer, further confirmed the existence of Ralstonia solanacearum pathogen in North East India.
