Grapevine viruses can shorten the life of infected grapevines and reduce both the quality and yield of grapes. Several viruses, especially those belonging to ‘rugose wood complex’, have been associated with graft incompatibility. In some cases, especially in many white grape varieties and non-vinifera rootstocks, virus-infected vines do not show symptoms and the virus can spread to susceptible neighbouring vines and vineyards. It is important to test propagation material prior to planting or grafting to avoid the risk of introducing or spreading viruses. This page provides links to a range of resources on viruses that affect grapevines.
