First report of Xanthomonas axonopodis pv. citri in Somalia
In 2006 and 2007, symptoms of citrus canker were observed on 8- to 10-year-old lime (Citrus x limetta) and grapefruit (Citrus x paradisi) trees in Northern and Southern Somalia, respectively. Ten leaf samples showing suspect symptoms were collected and tested (real-time PCR, pathogenicity tests) in a USDA laboratory (Fort Detrick, Maryland, US). The presence of Xanthomonas axonopodis pv. citri (EPPO A1 List) was confirmed in 5 grapefruit samples collected from Southern Somalia but it was not detected in lime samples collected from the northern part. This is the first report of citrus canker in Somalia.
The situation of Xanthomonas axonopodis pv. citri in Somalia can be described as follows: Present, first observed in 2006/2007 and confirmed in 2008 on 5 samples.
