Erwinia amylovora is a bacterial disease affecting fruit trees (Cotoneaster, Crataegus, Malus,<br />

Pyrus, etc.) and rosaceous ornamental plants. Insects are a vector for spreading the HO as the<br />

bacteria grows on flower surfaces. When climatic conditions are adequate, infection starts in<br />

the flowers. Erwinia amylovora causes cell destruction and plant tissue necrosis. Spread by<br />

propagating material is also probable.<br />

The HO comes from North America and is present in several European countries, including<br />

AT, BE, BG, DK, FR, DE, EL, HU, IE, NL, PL, RO, SK, ES and UK.<br />

Economic benefits<br />

Erwinia amylovora causes substantial damage to host plants. It endangers both the crops and<br />

the plants themselves. Yield in both the current and following year may be substantially<br />

reduced. Due to the rapid spreading of the HO in infested trees, trees can often not be saved.<br />

In order to avoid infestation, chemicals may be used.<br />

Economical damages may thus be substantial, including the destruction of trees, loss of crops,<br />

and replanting of trees or switching to other cultivations.<br />

Main sectors at risk are the pear and apple industries, and the nursery trade. The value of<br />

orchards of apple trees has been estimated at €6,000/ha by one MS.<br />

Environmental benefits<br />

The potential impact of Erwinia amylovora on the environment is really significant, based on<br />

the fact that host plants are widespread in the countryside; park and gardens, where they are<br />

positively contribute to the natural habitat.<br />

For instance in IE, the most important of the hosts of this HO is Crataegus which is<br />

widespread in the Irish countryside. Cotoneaster and Sorbus are extremely popular<br />

ornamental trees in Irish parks and gardens. The berries of these plants are recognised as very<br />

important sources of food for wildlife during the winter months. These plants also provide an<br />

abundance of shelter and nesting sites for wildlife and birdlife.<br />
