Detection of Pseudomonas solanacearum in Wild Arachis Spp Imported from Brazil uri icon

abstract

  • Groundnut bacterial wilt (Pseudomonas solanacearum) (=Ralstonia solanacearum) was intercepted on wild Arachis spp. when these were grown for quarantine clearance in the Post Entry Quarantine Isolation Area (PEQIA) at ICRISAT center, Patancheru, Andhra Pradesh, India. These accessions were imported from Brazil. Also, there is no record of groundnut bacterial wilt occurrence in Andhra Pradesh. The symptoms of the disease expressed at temperatures more than 30°C. Occurrence of bacterial wilt on accessions from Brazil where the disease has not yet been reported indicates that the pathogen is possibly transmitted in ?latent form? from one generation to the next in groundnuts grown under temperate conditions
