I'm nearly certain that the 10 new Cabernet Sauvignon vines I planted this spring are infected with grapevine leafroll virus (GLV). By mid-summer the leaves started to exhibit the classic inter-veinal reddening and downard rolling of leaf margins. From what little I've read, it seems that the virus is typically propagated through cuttings and secondary vectors not spread from plant to plant by contact or seed.
Anyone have experience with this? I purchased these vines from Double A vineyards in NY. Should I ask for replacement vines?
