DistributionTop of page R. solanacearum is comprises sub-populations variously reported as groups, races, biovars, biotypes, sub-races and strains. The commonly applied terms biovar and biotype refer to differences in biochemical and phage reactions (Hayward, 1962). Races, distinguished on the basis of differences in plant host range (Buddenhagen et al., 1962), are usually referred to in this text. The distribution is given for confirmed Ralstonia solanacearum race 1 or presumed race 1 based on host range. This race has a wider host range than race 3 and a higher temperature optimum (35-37°C).

The distribution in this summary table is based on all the information available. When several references are cited, they may give conflicting information on the status. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.Last updated: 23 Apr 2020
Hosts/Species AffectedTop of page Lists of host records have been recorded (Kelman, 1953; Bradbury, 1986; Persley, 1986; Hayward, 1994) but the original reports, gathered over many years, vary greatly in reliability. Few reference strains of race 1 from reported host plants have been deposited in publicly accessible culture collections to support the authenticity of records. There are many solanaceous and non-solanaceous plant species that are hosts to R. solanacearum. They can only be ascribed to known and possibly novel races when strains from them are isolated and examined.
