Beet necrotic yellow vein furovirus present in Czechoslovakia
Beet necrotic yellow vein furovirus (EPPO A2 organism) is present in the Czech and Slovak Federal Republic.
A survey was carried out in the southwestern part of Slovakia in which suspicious plants were collected from 23 localities around Bratislava. In several samples the virus was detected by host range studies, electron microscopy and serological methods. Later field observations showed that the virus is present in an area of 50 x 150 km and that at some locations the yields declined down to 30 t/ha with a sugar content as low as 9 - 12%.
