Abstract

Isolation of Erwinia amylovora from blighted plums (Prunus domestica) and potato roses (Rosa rugosa).

Abstract

In 2000, from Miesbach, Germany, bacteria were isolated from plums and potato roses showing symptoms of fire blight. These strains were labelled MB1, MB2 and MB3. Cultural, molecular and pathogenicity tests showed that the isolated bacteria were strains of Erwinia amylovora. This is claimed to be the first report of fire blight naturally occurring on a species of Rosa.
