Sharka, caused by Plum pox virus (PPV) is the most dangerous infectious disease of cultivated stone fruit trees, inducing severe damages to fruit production. The main strains (Marcus, Dideron, Rec) affect apricot, European and Japanese plum, peach, and many hybrids used as rootstock, whereas cherry is infected only with two specific cherry strains and almond is infected only in experimental conditions. In 1982, the PPV strain Dideron occurred in Emilia Romagna and spread in several apricot and plum orchards, in 1995 the Marcus isolate began to cause an epidemic diffusion, mainly in peach orchards.

During the last 20 years, Sharka has been managed following the requirements of European legislation and the specific Italian decree on compulsory control measures against PPV, which defines the phytosanitary measures in orchards and nurseries: namely, inspections, compulsory eradication of PPV-infected trees, and delimitation of the cultivated areas as either pest-free or contaminated.

In 2014, the regional plant protection service (PPS) identified 9 areas (26.288 hectares) where PPV was established and impossible to eradicate.

PPS authorized nursery activities only in pest-free areas (and at least 300 m from any orchard) or in screen-house conditions.

The planting of varieties partially resistant to the Marcus isolate is suggested for areas where PPV is already endemic and the removal of infected plants is not compulsory. The Regional Administration supports breeding research to develop PPV-resistant varieties and, in the last 10 years, the PPS has carried out some trials to test the new seedlings and the new varieties for PPV tolerance/resistance, before inserting them in any certification program.
