Abstract
In fields of sugar beet (Beta vulgaris L. var. saccharifera) near Osijek and Županja (eastern Croatia) virus symptoms similar to those of beet necrotic yellow vein furovirus (BNYW) were observed on plant specimens in 1997. The main symptoms were pale greenish yellow foliage, upright leaves, reduced root size and root proliferation characteristic of rhizomania. Samples of sugar beet collected in the fields during June, July and August 1997 were checked for BNYW. In these samples BNYW v as revealed. This was established on the basis of test plant reactions, serology, electron microscope analysis of virus particles and soil transmission experiments. That is the first certain finding of rhizomania caused by BNYW in sugar beet in Croatia. Attempts to isolate BNYW from sugar beet growing in fields near Čakovec and Virovitica (northwestern and central Croatia, respectively), which also showed rhizomania symptoms, were unsuccessful.
