Fact Sheet for National Clean Plant Network for Berries. Interpretive Summary: Blackberry yellow vein disease is a complex disease that emerged in the southeastern United States at the turn of the 21st century. The disease is widespread along the east coast from the mid-Atlantic throughout the mid-south and rarely seen along the west coast. Technical Abstract: Blackberry yellow vein disease was first observed in the Carolinas in the 1990s but has increased to cause epidemics since 2000. The disease is caused by a combination of viruses, the identity of which is less important the number of viruses infecting a plant. The major viruses associated with this disease in affected fields are RNA viruses and include blackberry yellow vein associated virus which is transmitted by whiteflies, blackberry leaf mottle associated virus transmitted by eriophyid mites, blackberry chlorotic ringspot virus transmitted by seed and pollen, tobacco ringspot virus, transmitted by nematodes, seed and pollen, blackberry vein banding associated virus transmitted by mealybugs and blackberry virus E and Y, both speculated to be transmitted by eriophyid mites. Given the number of viruses and vectors associated with the disease it is not economical to actively control all vectors. The better approach is to start with clean material, tested free for all the viruses associated with the diseases and plant in areas that have not had previous history of the major viruses associated with the disease. |
