| Abstract: | Fireblight was first observed in Romania in 1992-08 near Braila, and shortly after in the pear collection of the Fruit Research Institute in Pitesti-Maracineni. Advanced symptoms indicated that the disease was present at least one year earlier. Symptomatology, fruit pathogenicity, selective culture media, hypersensitivity, agglutination and fatty acid class analysis confirmed the authenticity of the pathogen as Erwinia amylovora. Of the native Romanian fruit cultivars affected, apple cv. Delicios de Voinesti and pear cv. Aromat de Bistrita appear the most susceptible to fireblight. |
