First report of pear decline phytoplasma in Poland

In Poland, disease symptoms including premature foliage reddening and slow decline of pear trees (cv. Kiparyjska, Radcowka and Williams ‘Bon Chrétien’ grafted on Pyrus communis) were observed in some orchards. In two orchards, quick decline of pear trees was seen (cv. Patten grafted on Pyrus communis). Samples of roots and shoots have been tested (DAPI, PCR), and the presence of pear decline phytoplasma (EPPO A2 quarantine pest) was confirmed. This is the first report of this pathogen in Poland.
