Abstract

A brief account is given on the present situation of tristeza disease in the Mediterranean countries.
The recent developments in terms of presence, distribution, epidemiology and control measures are critically reviewed and analyzed.
Emphasis is laid on the necessity to intensify and extend the local monitoring activity and the use of citrus certified plant propagating material.
