Current pest situation evaluated by EPPO on the basis of information dated 2008: Present, widespread
Comments
Bacterial wilt of potato (presumably race3 biovar 2) is causing problems in potato production in Malawi

EPPO Reporting Service (1998/26) : R. Black (pers. comm.) proposes that the only existing record of Ralstonia solanacearum race 2 in Malawi is old and doubtful (and therefore the record appearing on CABI/EPPO disease map 784 was considered erroneous).
