Xanthomonas axonopodis pv. citri found in Zanzibar (Tanzania)
Xanthomonas axonopodis pv. citri (X. campestris pv. citri - EPPO A1 quarantine pest) was found in the island of Zanzibar (Tanzania) in 1991 on lime, and subsequently on sweet orange and lime in one orchard in 1992. The identity of the bacterium was confirmed at the Central Science Laboratory (UK) in September 1992. The Ministry of Agriculture, Livestock and Natural Resources in Zanzibar notified FAO in 1994 and announced the finding in the local newspapers. The status of citrus canker in mainland Tanzania is unknown but will be investigated in a current project on bacterial plant pathogens.
