Graft-transmissable Diseases of Grapevines

Grapevine is widely cultivated in many countries of the world. The crop contributes to the well-being of farmers, workers, the industrial sector and the economies of countries. Virus and virus-like diseases constitute a major limiting factor to the development, quality and productivity of grapevine. Once a plant is infected, there is no cure. This handbook is a reference guide for the detection and diagnosis of virus and virus-like diseases of grapevine. In using this guide farmers can ensure that new varieties introduced are healthy (virus-tested) and that factors that could contribute to infestation are eliminated.
