First report of Tomato chlorosis virus in the Republic of Korea
Tomato chlorosis virus (Crinivirus, ToCV – EPPO A2 List) occurs in the Republic of Korea. It was first found in 2013 on greenhouse tomato plants in Nonsan (Chungcheongnamdo), Iksan (Jeollabukdo), Hampyeong and Hwasun (Jeollanamdo), as well as in Jeju (Jejudo). During further studies, the presence of ToCV was detected by RT-PCR in root samples collected from the following 17 weed species: Cardamine flexuosa, Cerastium glomeratum, Chenopodium album, Conyza canadensis, Erigeron annuus, Ipomoea hederacea, Mazus pumilus, Phytolacca americana, Quamoclit coccinea, Solanum americanum, Solanum nigrum, Sonchus asper, Stellaria media, Trigonotis peduncularis, Vicia angustifolia var. segetalis, Vicia tetrasperma, and Youngia japonica. It is noted that these weed species might serve as virus reservoirs between tomato cultivation seasons.
The situation of Tomato chlorosis virus in the Republic of Korea can be described as follows: Present, only in some areas.
