Fireblight in Israel—1985. Observations and recommendations

Fireblight, caused by the bacterium Erwinia amylovora , was observed in Israel for the first time in 1985. Primarily, the disease affected several pear orchards. The pathogen was also isolated and identified from symptomatic tissue of apple and cotoneaster. The occurrence, severity and distribution of the disease in 1985 is discussed in relation to environmental conditions and horticultural practices. Although fireblight was widespread in 1985, overall damage from the disease was limited. Actions taken to confirm the presence of fireblight and to manage the disease during its first season of occurrence are discussed. Prospects for the occurrence of fireblight in Israel in the future are discussed and specific recommendations for management of the disease are presented. Based on its behaviour in other countries, fireblight is expected to become established in Israel and the disease will require constant management to minimize losses.
