The distribution of <i>Plum pox virus</i> (PPV), <i>Prune dwarf virus</i> (PDV), <i>Prunus necrotic ringspot virus</i> (PNRSV), <i>Apple chlorotic ringspot virus</i> (ACLSV) and <i>Apple mosaic virus</i> (ApMV) in naturally growing shrubs of blackthorn and road-bordering trees of plum and myrobalan, and of PPV, PDV, PNRSV and <i>Cherry leafroll virus</i> (CLRV) in sweet and sour cherry trees were investigated. The most widely distributed viruses were PPV in plums (74% of the investigated trees were infected); PPV, PDV, and PNRSV in myrobalans (26%, 11% and 18%, respectively), PDV in blackthorns (27%), and PDV and PNRSV in cherries (25% and 22%). PPV was not detected in sweet and sour cherries. The incidence of ACLSV and ApMV was negligible in individually growing trees of the genus Prunus in the Czech Republic.

During 2006&ndash;2008 field surveys were carried out in the important cherry growing areas of the Czech Republic to assess the incidence of Prune dwarf virus and Prunus necrotic ring spot virus in commercial orchards and nurseries. A total of 1,438 samples from 1,198 sweet cherry trees and from 240 sour cherry trees were tested by ELISA for the presence of Prune dwarf virus and Prunus necrotic ring spot virus. The overall average infection level was 17.7%. The most infected species were sour cherry trees (22.5%). The most frequently detected virus was Prune dwarf virus (10.9%). Prunus necrotic ring spot virus occurred in 6.3% of samples. Our study provided an indication of a sanitary status of sweet and sour cherry in commercial orchards and nurseries in the Czech Republic. &nbsp;

Niagara Escarpment

In the fruit belt of the Niagara Peninsula, wild Prunus avium and P. serotina are common along the Niagara Escarpment, the larger streams, and the Niagara River. P. virginiana is somewhat more widespread than the former species and P. pensylvanica is very rare. P. nigra and P. americana are limited in distribution. The necrotic ringspot virus (NRSV) was detected in trees of P. avium, P. serotina, and P. virginiana, whereas the prune dwarf virus (PDV) (sour cherry yellows) was found only in trees of P. avium and P. serotina. Because of the limited incidence and distribution of virus-infected trees, however, and because the bloom periods of the wild species rarely coincide with sour cherry, peach, or plum, wild Prunus species are considered relatively unimportant as potential reservoirs of virus for infection of commercial orchards.

The symptoms of a rosetting and decline disease of peach are described. Prunus necrotic ringspot virus (PRSV), prune dwarf virus (PDV), and a virus which causes a dark green sunken mottle (DGSM) on peach leaves have been isolated from diseased trees. Combinations of these viruses interacted synergistically in peach seedlings, but with considerable variation in the degree of synergism. The most severe expression of rosetting resulted from the interaction of all three viruses. Interaction between PRSV and PDV usually caused recurrent rosetting. PRSV and PDV were transmitted through the seed of rosetted peaches, but the latter in only a low percentage of seeds (max. 6%) and then only in combination with PRSV, which was transmitted to a maximum of 35.7 %. There was no evidence for seed transmission of DGSM. A study of natural spread of rosetting in a commercial planting of Golden Queen peaches showed that rosetted trees increased from 0.8 to 56.1 %, a total of 265 in 472 trees, in 7 years. Seedlings grown in soil obtained from the root zone of infected trees did not become infected.
