Scientific institutions of Lebanon are in great difficulty because of the lack of funds and the heavy damage suffered during the civil war. However research activity in fruit crops is being resumed thanks also to foreign support (including that provided by MAI-B and the University of Bari). By visual inspection the following diseases have been detected in citrus: blind pockets, concave gum, impietratura, psorosis A, cachexia, stubborn. Tristeza has not been reported, but a specific survey has not been carried out. Now a programme in collaboration with MAI-B and the University of Bari has been set up for the establishment of a certification programme for citrus, grapevine and stone fruits.
