First record of Xanthomonas axonopodis pv. poinsettiicola in the Czech Republic
In the Czech Republic, a company located in Brno asked the regional NPPO in July 2007 to identify the possible cause of symptoms observed on potted plants of poinsettia (Euphorbia pulcherrima) growing in a glasshouse. Samples were tested by the NPPO laboratory. These tests (gas chromatography) revealed the presence of Xanthomonas axonopodis pv. poinsettiicola (EPPO Alert List). Young plants of E. pulcherrima had been supplied from the Netherlands and Germany and the pathogen occurred on plants from both countries. No official measures were taken by the NPPO but all diseased plants were destroyed and symptomless plants were released for distribution to the final consumers within the country. This is the first report of X. axonopodis pv. poinsettiicola in the Czech Republic.
The situation of Xanthomonas axonopodis pv. poinsettiicola in the Czech Republic can be described as follows: Transient, it was detected in 2007 in a single glasshouse and affected plants were destroyed.
