What is phony peach disease?

Phony peach disease (PPD) is caused by a bacterium (Xylella fastidiosa) that spreads through the xylem (vessels that transport water and nutrients) of many plant species. Leafhopper insects transmit it. Though many infected plant species show no symptoms, it is a serious disease of peaches and several other hosts.

How can you prevent Xylella?

At present, when the disease is identified the only available measures to stop it spreading are preventative: destroying affected trees and plants, applying buffer zones around an outbreak site, and checking plants imported from areas affected by Xylella.

Where did Xylella fastidiosa come from?

Xylella fastidiosa subsp. pauca is believed to have originated in South America. It is the causal agent of citrus variegated chlorosis (CVC) in Brazil and also affects South American coffee crops, causing coffee leaf scorch.

How is Xylella fastidiosa diagnosed?

Positive identification of Xylella fastidiosa can be accomplished by three methods: enzyme- linked immunosorbent assay (ELISA), a serological test; polymerase chain reaction (PCR) analysis, a molecular method; and culturing the bacterium on selective media.

Why are olive trees dying in Italy?

The tree-killer is a bacterium called xylella fastidiosa. Since 2013, it has killed millions of olive trees in Italy and is now threatening those in Spain and Greece. Together, these countries produce 95% of Europe's olive oil.
