Species of virus

Grapevine leafroll-associated virus (GLRaV) is a name for a group of viruses that infect grapevine.[1]

Quick Facts Scientific classification, Groups included ...

Obscure mealybugs (Pseudococcus viburni) feed on the phloem of vines and woody-stemmed plants, especially pear and apple trees and grape vines.[2] Some individuals are vectors for infectious pathogens and can transmit them from plant to plant while feeding; mealybug-spread grapevine leafroll associated virus type III (GRLaV-3), in particular, has wreaked havoc among the grapes of New Zealand, reducing the crop yield of infected vineyards by up to 60%.[3]

The biggest problems in Grapevine Leafroll Disease are reduced grape yield, altered grape ripening, and altered grape chemistry.[4]: 623  Leafroll viruses are associated with rugose wood condition of grapevine.[5]
