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.
