Details on the situation of Grapevine flavescence dorée phytoplasma in Friuli-Venezia Giulia, Italy
In the region of Friuli-Venezia Giulia, the presence of grapevine yellows has been observed since the 1980s. Bois noir phytoplasma (i.e. stolbur) occurs in this region and in 1996, the presence of Grapevine flavescence dorée phytoplasma (EPPO A2 quarantine pest) was confirmed in the Province of Pordenone, at the border of a larger focus located near Valdobbiadene in the Veneto region. As both the extent and incidence of flavescence dorée was low, eradication was considered to be feasible. Eradication measures include compulsory control of the vector Scaphoideus titanus and systematic destruction of all diseased grapevines (with compensation for the growers). In spring 2000, the disease was not observed in the Provinces of Gorizia, Trieste and Udine. Flavescence dorée was only found in some parts of the Province of Pordenone (Caneva, Sacile, Fontanafredda, Porcia, Brugnera, Prata di Pordenone). In 2001, the disease was found in a few new localities in the Province of Pordenone (Pasiano di Pordenone, Roveredo in Piano). However, its incidence in 2001 was lower than in 2000. Eradication measures and surveys will continue in this region.
