First report of Xanthomonas citri pv. citri in Burkina Faso
In July 2011, citrus canker was suspected in Burkina Faso in the area adjacent to the Sikasso province of Mali where Xanthomonas citri pv. citri (EPPO A1 List) has been confirmed. In November and December 2012, leaves of clementine (Citrus clementina), lemon (C. limon), Volkamer lemon (C. volkameriana), sweet orange (C. sinensis), tangelo (C. paradisi x C. reticulata) and mandarin (C. reticulata) were collected from orchards with trees showing symptoms of citrus canker in the Comoé, Houet and Kénédougou provinces of Burkina Faso. Laboratory analysis (isolation on semi-selective medium, PCR, sequencing, biological tests) confirmed the presence of X. citri pv. citri. This is the first time that X. citri pv. citri is reported from Burkina Faso. It is noted that surveys are needed to determine the distribution of citrus canker in Burkina Faso, that sanitation measures should be taken in orchards to reduce disease prevalence, and that citrus canker-free nurseries should be established.
The situation of Xanthomonas citri pv. citri in Burkina Faso can be described as: Present, first detected in December 2012.
