  Introduction
  Virus diseases have a major impact on the productivity of cultivated plants,
  especially vegetable and fruit crops, in very diverse agricultural ecosystems.
  Suppression of their impact is almost impossible because of the systemic and
  non-curable nature of virus infections in the field. In many important crops
  virus-resistant or -tolerant cultivars of good agronomic quality are lacking.
  When available, resistances may break down due to the variability and the
  diversity of plant viruses. In this context, cross-protection appears to be a
  potentially useful component of an integrated virus management strategy.
