Grapevine leafroll-associated virus 3
Virus classification
Group: Group IV ((+)ssRNA)
Family: Closteroviridae
Genus: Closterovirus
Species: Grapevine leafroll-associated virus
Subspecies: Grapevine leafroll-associated virus 3

Grapevine leafroll-associated virus 3 (GRLaV-3) is virus infecting grapevine in the genus Closterovirus.[1][2]

Obscure mealybugs (Pseudococcus viburni) feed on the phloem of vines and woody-stemmed plants, especially pear and apple trees and grape vines.[3] 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, in particular, has wreaked havoc among the grapes of New Zealand, reducing the crop yield of infected vineyards by up to 60%.[4]
