In 1955 a severe wilt disease occurring on ginger in the Near North Coast district of Queensland was incorrectly attributed to infection by a Fusarium sp., and later shown to be caused by a strain of Ralstonia solanacearum, now reclassified as R. sequeirae. The disease was brought from China into Australia on latently infected rhizomes, and possibly also with associated soil. Several DNA-based diagnostic methods have shown that the pathogen causing bacterial wilt of ginger in parts of China is indistinguishable from the pathogen uniquely associated with the disease in Queensland.
