Present situation of beet necrotic yellow vein benyvirus in Sweden


In 1996, beet necrotic yellow vein benyvirus (EPPO A2 quarantine pest) was found in three farms in Sweden. In 1999, a national survey showed that rhizomania occurs in 26 farms located in 4 more or less distinct areas. Phytosanitary measures have been taken in farms where the virus was found, and include the following: 1) beets or other host plants are not included in crop rotation more than once in four years; 2) only resistant or tolerant beet cultivars can be grown; 3) beet crops are harvested on one occasion and the machinery is immediately cleaned; 4) all beets are delivered in one occasion to one sugar factory (having appropriate water outlets); 5) beets are freed from soil as much as possible; 6) all agricultural machinery is cleaned before leaving the farm.
Note: the EPPO Secretariat had previously no data on the occurrence of this virus in Sweden.
