“…Symptoms include other abnormal shapes, colors, or forms of leaves and fruits, premature drop of fruits, fruit lesions, etc. Asymptomatic infection may be more prevalent in warmer climates [5]. In general, infected plants can take several months to show symptoms and their appearance may be temporary and fade during the summer months [3,6].…”

“…More than 20 species of aphids can transmit the virus in a non-persistent manner, of which the species Myzus persicae is one of the most efficient in doing so [4]. The intensity of spread depends on several factors, including the efficacy of the aphid species in transmitting and its abundance of winged forms, the winds in the area, and the presence of susceptible cultivars around [5]. The virus can also be transmitted through vegetative propagation techniques in nursery trading such as grafting [3][4][5]7].…”

“…Hence, infected trees serve as a reservoir for the virus if not eradicated, as well as nearby infected weeds and cultivars, due to the action of virus vectors. Consequently, PPV control relies on public and private prevention measures, such as laws and norms that regulate the trading of vegetative material susceptible to PPV and control illegal exchange trafficking; strict quarantine regulations for nursery stock; chemical vector control; proper eradication of infected material; and the control of weeds and susceptible vegetation [4,5].…”

Sharka is a disease affecting stone fruit trees. It is caused by the Plum pox virus (PPV), with Myzus persicae being one of the most efficient aphid species in transmitting it within and among Prunus orchards. Other agricultural management strategies are also responsible for the spread of disease among trees, such as grafting and pruning. We present a mathematical model of impulsive differential equations to represent the dynamics of Sharka disease in the tree and vector population. We consider three transmission routes: grafting, pruning, and through aphid vectors. Grafting, pruning, and vector control occur as pulses at specific instants. Within the model, human risk perception towards disease influences these agricultural management strategies. Model results show that grafting with infected biological material has a significant impact on the spread of the disease. In addition, detecting infectious symptomatic and asymptomatic trees in the short term is critical to reduce disease spread. Furthermore, vector control to prevent aphid movement between trees is crucial for disease mitigation, as well as implementing awareness campaigns for Sharka disease in agricultural communities that provide a long-term impact on responsible pruning, grafting, and vector control.

Plum pox virus (PPV) is the most dangerous viral agent of stone fruits. PPV can be transmitted by vector aphids and may cause serious damage on fruits, leaves and flowers of Prunus species, especially on plum, apricot, and peach. Eradication of infected plants is one of the most recommended control methods of PPV in the world. The main objective of this study is to evaluate the National PPV survey and eradication program carried by the National Plant Health Authority between 2013 and 2018. During the six years of study, approximately 60.000 trees in 96.26% of Turkey were screened for PPV symptoms and 21.394 samples were collected from suspected plants from seven different fruit species. The samples were tested by ELISA (Enzyme Linked Immunosorbent Assay), and then ELISA questionable samples were verified by RT-PCR (Reverse Transcription Polymerase Chain Reaction). Based on the six years results, 2.718 samples from 161 locations were determined as PPV positive and the infection rate was calculated as 12.70%. During this study, 78.868 trees were eradicated. By the help of intensive monitoring and eradication program, PPV infection rate decreased from 35.72% to 7.47%. On the other hand, PPV infection was firstly recorded and eradicated in seven provinces (Aydın, Bolu, Denizli, Erzincan, Kırıkkale, Sivas, Samsun) which have been knownas PPV-free before. This study showed that eradication is a very effective way to suppress PPV infection and spread. In conclusion, the national survey and eradication program should be operated nationwide and concentrated in nurseries.
