“…Based on serological analysis of more than 3000 leaf samples of Prunus spp., the highest level of PPV infection was detected in plum (82%), followed by peach (40%) and apricot (32%) (Kamenova & Borisova, 2019). A high infection rate in plum cultivars grown in our country are reported by, Kamenova & Milusheva (2005), Dragoyski et al (2009Dragoyski et al ( , 2010, Petrov (2014) and Borisova & Sotirov (2021), but by ELISA tests on leaves, not on flowers. There are no known treatments of the disease that can be used once the tree becomes infected.…”

“…Infected trees have to be destroyed. Once the disease has been identified, measures to control and prevent plum pox include conducting field examinations, using certified nurseries, controlling aphids and eliminating infected trees in nurseries and orchards (Németh, 1994;Kamenova et al, 2003;Borisova & Sotirov, 2021).…”

Since ancient times, the fruits of the plum have occupied an important place on the table of the Bulgarians. To obtain high and stable yields an important condition is the proper organization and conduct of plant protection activities and the fast, the correct and accurate diagnosis of PPV - Stoneware. In our climate, Plum pattern manifests symptoms first on the first spring leaves. The described symptoms of flowers in different stone species are few and scarce, so we conducted the present study in two following years 2019 and 2020 to describe, differentiate and compare visual symptoms of flowering with the results of DAS-ELISA tests on the leaves of the studied stone species. From the surveyed PPV host species in two orchards 12 mather trees with color symptoms were selected and described in two regions of Bulgaria - the Sofia field (Vrajdebna (1,2 ha) and the Vratsa region (Roman Orchard Nursery (0,4 ha). In a total of 9 samples, PPV infection was confirmed. The established deviations were found only in fruit crops that bloom with white flowers. Based on the results and conclusions, the present study will contribute to the timely detection of the causative agent of pox virus in the earliest symptoms in nurseries and gardens and will provide the right and quick direction to overcome the damage through proper plant protection activities

“…It is an incurable viral disease of trees of the genus Prunus (apricot, peach, plum, mirabelle, etc.) [1] . It spreads from tree to tree and from orchard to orchard [2] (see in Figure 1, how the orchards might be closely interlinked) and is transmitted by aphids [3] .…”

On the possible impacts of a regulatory change on resource conservation: The case of the plumpox virus in France

Preserving natural resources in the context of global change includes looking at how to protect trees, whether in forests or for fruit production, from various epidemic diseases. A change in European regulation presently underway (EU 2016/2031; currently, in 2023, transitional measures are being implemented in France) transfers, from the public authorities to the profession (all the tree growers susceptible to be concerned), the responsibility for detecting plum pox virus, which has the potential to damage virtually all stone fruit orchards, and for eliminating the affected trees. Yet the disease is a viral one, transmitted by a vector (aphids) from tree to tree and from orchard to orchard. Within a few years, fruit from contaminated trees can no longer be marketed. We show here that, in the context of this new regulation, the heterogeneity of the tree growers (due to the size of the orchards, the diversification of the crops, the future of the farm...) can lead to a recrudescence of the disease throughout the stone fruit orchards. This would also imply all kind of negative effects on the economic (employment in the agricultural sector, national trade balance, processing and marketing sector activities...), social and environmental (landscapes...) levels. The results can easily be generalised to any problem of conservation of natural resources whose management is delegated to private stakeholders.

First molecular characterization of plum pox virus strains in stone fruits of Tuscany (Central Italy)

2023

Plum pox virus (PPV) a potyvirus in the family Potyviridae, is the etiologic agent of sharka, the worldwide most important and detrimental viral disease of stone fruits (genus Prunus). Although PPV was identified in Italy already in the 1970s and it has been largely reported in almost all Italian regions, a broad investigation and genetic characterization of PPV isolates was lacking in most of them, including Tuscany (Central Italy). To address this knowledge gap, in 2020 and 2021, field surveys were carried out in 80 commercial Tuscany orchards and a total of 690 leaf samples were collected from different Prunus species. PPV was identified in 25 and 12 peach and plum samples, respectively (more than 5% of tested samples), whereas no positive samples were reported in apricot. Eighteen of the 37 PPV positive samples showed mixed infections with other viruses and viroids, mostly Prunus necrotic ringspot virus in plum and peach latent mosaic viroid in peach. Molecular typing of PPV infected samples generated NIb/CP amplicons corresponding to PPV-Marcus (M) or PPV-Recombinant (Rec) strains. Furthermore, starting from the identification of eight PPV nucleotide sequences (among which five and two new PPV-M and PPV-Rec isolates, respectively), this study firstly identified the PPV-Mb subgroup in Italy, which was even prevalent than PPV-Ma. Finally, PPV-Rec isolates resulted phylogenetically close to Italian and Turkish isolates previously detected. Overall, the results here presented represent an important step to fill knowledge gaps about PPV in Tuscany, and we believe it may encourage other similar research to achieve more accurate data on PPV populations at both national and international levels.
