Cottin, R. | Bourdeaut, J. (IFRA/CIRAD, Martinique (France))
Virus and viral-like diseases have a major impact on citrus production worldwide and often become the dominant yield-limiting factor in grove management. The most obvious impact of these diseases is their lethal effect on specific hosts. Less obvious but of equal economic importance is the non lethal response that reduces tree size, vigour and fruit yield. Citrus virus and viral-like diseases may also restrict the grower's choice of rootstocks and scions which can be grown profitably in certain areas. Describes the symptoms of two major diseases of citrus: Exocortis, a viroid disease and Tristeza, a virus disease. Discusses their diagnosis in the field and in the laboratory and reviews information on control measures for these kinds of diseases for citrus.
