Cotoneaster dammeri: Fire Blight (Erwinia amylovora) Resistant Cultivars in Germany

Heinrich Lösing

pp: 123-124


The bacteria disease fire blight first appeared in 1971 in Schleswig - Holstein on Crataegus monogyna and Pyrus fruit trees. It spread south, reached Hamburg in 1974, Westfalia in 1975, and finally the southern parts of Germany in 1981 (Baumm, 1989). Initial attempts at control included strict eradication of C. monogyna from windbreaks, especially in nurseries and around infested locations. Commercial production of common hawthorn was banned. These restrictions could not stop Erwinia amylovora. Nowadays people have learned to live with the disease, which is mainly found in Germany on Chaenomeles, Cotoneaster, Crataegus, Cydonia, Pyrus, and Photinia.
