First report of Xanthomonas axonopodis pv. dieffenbachiae in Réunion
In Réunion, Xanthomonas axonopodis pv. dieffenbachiae (EPPO A1 quarantine pest) was first observed in 1997 during routine inspections. It was found in 2 nurseries on Anthurium andreanum plants imported from the Netherlands. The disease rapidly spread to other Anthurium plants in the nurseries causing severe damage. Between 1997-1999, 114 isolates were collected from 3 main locations: the 2 nurseries where the disease had originally been found, and another nursery which was later found contaminated. All isolates were identified as X. axonopodis pv. dieffenbachiae. Since 1997, phytosanitary measures are being applied and include the following: destruction of all affected plants, infected nurseries are placed under quarantine, surveillance at entry ports is intensified to prevent any further introduction. This is the first report of X. axonopodis pv. dieffenbachiae in Réunion. The situation of X. axonopodis pv. dieffenbachiae in Réunion can be described as follows: Present: found only in a few areas, under eradication.
