Comparison of damage caused by beet necrotic yellow vein virus and beet soilborne virus 2
A comparative study to investigate the yield loss of sugarbeet due to infection by Polymyxa betae, beet necrotic yellow vein virus (EPPO A2 quarantine pest) and beet soilborne virus serotype 2 were carried out at the University of Giessen, Germany.
Pot and field experiments were conducted and it was found that there were significant differences between BNYVV and BSBV-2. BNYVV induced a quantity loss of 40% while BSBV caused only 26% yield loss. The quality of the sugarbeet was reduced by 55% through the BNYVV infection while the BSBV infection accounted for 35% quality loss.
