First report of Iris yellow spot virus in Greece
From February to June 2008, 530 onion (Allium cepa) and 439 leek (A. porrum) samples showing different types of lesions were collected from several areas of Greece and tested for the presence of Iris yellow spot virus (Tospovirus, IYSV – EPPO Alert List). All sampled plants were infested with Thrips tabaci. IYSV was detected in both onion and leek samples collected from different prefectures, suggesting that the virus is already well established in Greece.
- On onion, IYSV was found in the following prefectures: Evros (detected in 36% of the tested samples), Heraklion (44%), Kavala (23.7%), Magnissia (61.7%), Pella (10%), Rodopi (55%), Thessaloniki (15.3%), Viotia (9.4%).
- On leek, IYSV was found in the following prefectures: Evros (5%), Pella (9.3%), Thessaloniki (13%).
