Commercial varieties show symptoms only if they have been grafted on Virginia Crab, although the virus can cause latent infection in other rootstocks. If infected, the root system weakens and declines, causing the dieback of the scion. Sunken depressions and grooving develop on the stem and the limbs below the union, and longitudinal sutures appear on the bark. In its mild form, symptoms develop only after the second year following inoculation. If severely infected, moderate pitting in the wood occurs during the second year worsening thereafter.
