Resumo: The objective of this study was to characterize isolates of biovar 2 of Ralstonia solanacearum pathogenic to eucalyptus "urograndis" hybrid by means of biochemical tests, as well as evaluation of host range and identification by PCR with primers for species, biovar and phylotype. Carbohydrate utilization assays revealed that the eucalyptus isolates belong to phenotype Tropical of biovar 2 (2T). From artificial inoculations it was possible to reproduce symptoms or recover the bacterium from: eucalyptus, potato, tomato, eggplant, datura, geranium, turnip, mustard, nasturtium, beetroot, sunflower, bean, French marigold, horseradish tree, and cashew. The PCR assays confirmed that the isolates belong to biovar 2, phylotype II of the bacterium. The confirmation of new biovar naturally infecting eucalyptus indicates that R. solanacearum easily adapts to new hosts.
