May 2018


Grapevine yellows (GYs) are mainly spread in European viticultural areas. Phytosanitary measures worldwide are based on data obtained on classical pathosystems, but the latest findings suggest that the epidemiological pattern of these diseases is evolving and adapting to different ecological conditions. Risk assessment of introduction in GY-free areas has to be reconsidered in view of the broadening of the range of pathways of entry and means of diffusion in the field. The purpose of this review is to make available an update on findings of recent years to provide useful tools to prevent further spread of these serious diseases of grapevine.
