This paper reviewed current literature concerning the problem of rhizomania disease caused by Beet necrotic yellow vein virus (BNYVV, Benyvirus). At present, it is considered as a serious problem in almost all sugar beet growing regions of the world. Some details conceming virus taxonomy and compositions of BNYVV genome, virus transmission and disease spreading as well as the methods of virus detection and control of rhizomania disease are described. In Poland the occurrence of the BNYVV, especially due to favorable conditions for its vector Polymyxa betae can still make sugar beet production uneconomic. Taking into consideration the first report about considerable lasses the most urgent task is to restrain the spread of rhizomania.

Beet necrotic yellow vein virus - the agent causing rhizomania was for first time detected in Poland in 1987. In 1987-1988 the samples from 204 sugar beet fields with the plants showing the symptoms of rhizomania, were tested with ELISA test and in 64 of them the presence of virus was observed. In 1989-1990 occurrence of virus was recorded only sporadically. In next years (1992-1995) the studies carried out in area of high virus occurrence did not confirm the thesis about spreading of the disease. Positive results of ELSA test were confimed with ISEM and Western blotting.
