Survey in Algeria does not find Erwinia amylovora
A survey was undertaken for the possible presence in the Alger region of fireblight, due to Erwinia amylovora (EPPO A2 organism), a dangerous disease of rosaceous pip fruit and ornamentals.
A total of 196 samples were carefully collected from seven pear orchards, which were regularly visited and represented a total area of 35,76 ha, with 150.033 trees. From this material 107 isolations were made. No strain of E. amylovora was found. However, 24 strains of Erwinia were obtained: 13 E. chrysanthemi, 9 Erwinia-like and 2 E. carotovora carotovora. The survey was limited to one area.
