Update on the Rhizomania situation in the EC (United Kingdom)
It was reported at the International Symposium on Plant Health and the European Single Market in Reading (UK) that during 1992 13 new outbreaks of rhizomania caused by beet necrotic yellow vein furovirus (EPPO A2 quarantine pest) have occurred in eastern England. Studies from outbreaks in 1989 resulted in a decrease of root weight and sugar yield of sugar beets by 42% and 44%, respectively.
