Situation of beet necrotic yellow vein furovirus in Hungary
Rhizomania, caused by beet necrotic yellow vein furovirus (EPPO A2 quarantine pest) is one of the most important factor causing yield reduction on sugar beet in Hungary. Studies have been carried out in 40 sugar beet plots, in four counties (Borsod-Abauj-Zemplén, Fejér, Heves, Szabolcs-Szatmar-Bereg). The virus was identified by ELISA tests. In these four counties, the average infection level varied from 7.4 to 42.8 %. The lowest incidence was observed in Szabolcs-Szatmar-Bereg county and the highest in Fejér county.
