Tomato spotted wilt virus found in Czechoslovakia
Frankliniella occidentalis (EPPO A2 pest) the vector of tomato spotted wilt virus (potential EPPO A2 quarantine organism) has been present in Czechoslovakia since 1989. However, the virus did not appear in recent years.
In 1992 several plants from three commercial growers showed typical symptoms of tomato spotted wilt virus infection. Samples were analyzed by ELISA and found to be infected by the lettuce strain of the virus. Infected plants were chrysanthemums, begonia, tomato, pepper, Zantedeschia aethiopica and the weed Galinsoga parviflora.
