Fire blight and the pathogen Erwinia amylovora were subjects of field observations and laboratory tests within a period of 17 years (1989/2005). It was proved that the disease is spread through over the country being meanwhile registered in regions of all administrative districts. From all seven hosts, more than 400 isolates were obtained, most of them preserved in a collection and identified as E. amylovora strains. Some data on field susceptibility of quince, apple and pear cultivars to fire blight were obtained, also a quince breeding program has been run. A complex of preventive measures and some strategic approaches were outlined, too.
