[Two viruses are associated with lettuce big-vein disease]

Abstract: Since many years lettuce big-vein disease (LBVD) occurring in lettuce (Lactuca sativa) and endivia (Cichorium endivia) is a well known disease. It is widely spread all over the world and can cause important economical losses. For more than 20 years the lettuce big-vein virus (LBVV) was thought to be the causal agent. New results indicate that another virus, named `Mirafiori lettuce big-vein ophiovirus ' (MLBVV), is responsible for the typical symptoms. Mostly both viruses are detected together in diseased plants. But also the presence of only one virus can be observed as shown in a sample which was sent to the Bavarian State Research Center for Agriculture (LfL), Freising, in the spring of 2005. In further investigations at the German Federal Authority and Federal Research Centre (BBA), Braunschweig, only the MLBVV was found. Like any other virus disease LBVD cannot be controlled directly. Therefore prevention is of utmost importance. If LBVD is already present integrated disease management strategies combining cultural and phytosanitary measures as well as growing tolerant lettuce cultivars are the only way to minimize economical damage.
