Moko disease (Ralstonia solanacearum race 2) is not present in Jamaica and its presence in Malawi is doubtful
The EPPO Secretariat has been informed that according to the official authorities of Jamaica, Moko disease of banana, caused by Ralstonia solanacearum (EPPO A2 quarantine pest) race 2, has never been found in this country. The record in the 2nd edition of Quarantine Pests for Europe is therefore erroneous.
In addition, doubts were expressed also on the occurrence of the disease in Malawi, as according to plant pathologists it has definitely not been seen in recent years. The single record is rather old and could not be verified. The record in the 2nd edition of Quarantine Pests for Europe can therefore be considered dubious.
