The Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) confirmed detections of Ralstonia solanacearum race 3 biovar 2, on geraniums with wilt symptoms in greenhouses in February of 2003 and again in December the same year.  In both cases, the vast majority of geraniums were from one supplier, with the first instance originating from Kenya and the later instance from Guatemala. The first plant confirmed positive by PPQ occurred on February 11, 2003, subsequent eradication commenced February 26, 2003, and ended May 1, 2003. In the second detection, the first confirmed positive plant occurred December 30, 2003, eradication commenced January 2004, and ended March 15, 2004. Ralstonia solanacearum race 3 biovar 2 has not been detected in the US since it was last eradicated in 2004. Furthermore, Ralstonia solanacearum race 3 biovar 2 has never been detected outside of a greenhouse. Strong offshore production, inspection, and certification requirements are operating to prevent repeat incursions of infected geraniums, as well as on imported propagative material of Solanaceous hosts.
