Present situation of Erwinia amylovora in Austria
The EPPO Secretariat has recently been informed by the Austrian Plant Protection Service of the present situation of Erwinia amylovora (EPPO A2 quarantine pest).
- Situation in Vorarlberg (from 1993 to 1998)
In Austria, fireblight was first reported in 1993 (see EPPO RS 94/172) in the region of Vorarlberg state (on a few plants in one village). In this region, from 1993 to 1998, fireblight spread from this initial focus to a few localities. Intensive eradication measures were taken, and the disease could successfully be eradicated in some foci. In Vorarlberg state, the forecasting programme 'Maryblight' has been used, and in 1998 the application of streptomycine-sulphate during the flowering period has been allowed under strict security conditions. In Vorarlberg state, the infestation remains limited.
- Situation in other regions in 1998
In August 1998, an outbreak of fireblight was observed in some localities of Tyrol state. The disease occurred on old apple and pear trees in extensive fruit production. In September 1998, the disease was observed in a single place near Salzburg, on trees in extensive fruit production.
In all infested areas, intensive eradication measures were immediately taken (partial or complete destruction of infested plants). Surveys in all regions of Austria are being intensified and fruit producers, nurseries and bee-keepers are well informed about the risks. All nurseries are intensively inspected, and so far they have been found free from fireblight.
