Further details on an earlier finding of Ralstonia solanacearum on Pelargonium in Pennsylvania (US)
In EPPO RS 2001/124, the presence of Ralstonia solanacearum (EPPO A2 quarantine pest) on Pelargonium was reported in Pennsylvania (US) without further details. It is now known that Pelargonium plants infected by R. solanacearum biovar 2, race 3 were found in 3 glasshouses in 1999 and in 2 glasshouses in 2000. The infected Pelargonium cultivars originated from propagators in Guatemala or Mexico.
