First report of Cucurbit yellow stunting disorder, Tomato chlorosis and Tomato infectious chlorosis criniviruses in Greece
In 1997, yellowing symptoms were observed, at low incidence, on glasshouse tomato plants in southern Greece and Crete. By 2001, the distribution and incidence had increased to the majority of glasshouse tomatoes. In most cases, disease incidence reached 80 to 90 %, or even 100%. In field-grown tomatoes, similar symptoms appeared but at lower incidence. These epidemics were associated with high populations of whiteflies (Trialeurodes vaporariorum and Bemisia tabaci). Molecular tests revealed the presence of Tomato chlorosis (ToCV) and Tomato infectious chlorosis (TICV) criniviruses (both on the EPPO Alert List). In a large scale study, infected tomato samples were collected from mainland Greece (mainly Peloponese but also Macedonia), and from the islands of Poros, Rhodos and Crete. TICV was found in the majority of symptomatic samples (89 %), including in some samples collected from open-fields. ToCV was detected in tomato samples from Rhodos, Poros, Crete and Pella (Macedonia), but only in glasshouse tomatoes. A few mixed infections were detected in Crete and Poros. This is the first report of Tomato chlorosis and Tomato infectious chlorosis criniviruses in Greece.
The situation of Tomato infectious chlorosis crinivirus in Greece can be described as follows: Present, widespread in glasshouse tomatoes (mainland Greece: Peloponese, Macedonia, islands of Poros, Rhodos, Crete), few reports from field-grown tomatoes.
The situation of Tomato chlorosis crinivirus in Greece can be described as follows: Present, found only in glasshouse tomatoes (mainland Greece: Macedonia, islands of Poros, Rhodos, Crete).
Note: In the same paper, the presence of Cucurbit yellow stunting disorder crinivirus (EPPO Alert List) is reported on cucumber and melon, from the islands of Rhodos and Poros, and Leonidio in eastern Peloponese. The EPPO Secretariat had previously no data on its occurrence in Greece.
The situation of Cucurbit yellow stunting disorder crinivirus in Greece can be described as follows: Present, few reports (mainland Greece: eastern Peloponese, islands of Poros and Rhodos).
