First report of Xanthomonas axonopodis pv. dieffenbachiae in Turkey

In spring 2001, a serious outbreak of a bacterial-like disease was observed on Anthurium andreanum plants grown for potted plant production in commercial glasshouses of the Mediterranean region, in Turkey. Disease incidence reached 20-25 %. Affected plants showed yellowish water-soaked lesions that enlarged and coalesced. Brown to black blighted areas were often observed together with a striking yellow zone along leaf margins. Bacterial ooze was also observed. 18 bacterial strains were isolated from diseased plants and identified as Xanthomonas axonopodis pv. dieffenbachiae (EPPO A1 quarantine pest) by using fatty acid profiles and pathogenicity tests on anthurium plants. This is the first report of this bacterium in Turkey. The situation of Xanthomonas axonopodis pv. dieffenbachiae in Turkey can be described as follows: Present, only in protected cultivation. Found in 2001 on Anthurium andreanum, in the Mediterranean region.
