During 1989 and 1990, disease qymptoms were observed on Pinus pinea, P.
halepersls and P.
brutia in nurseries and artificial forests at Kamari, Kusaibia, Tel Hadya, Kfar Halep, Jabal Soula and Jinderiss in Aleppo and Idlib Governorates.
It was also observed along the main roads of Aleppo-Homs, Aleppo-Jericho, Aleppo-Bab El-Hawa and Aleppo-Mouselmieh.
The syrnptoms observed included yellowing of pine needles which turn into btighted alternata, Ascochyta sp., Aureobasidium pullulans, Leptostroma pinastri, Lophodermium pinastri, Mycosphaerella sp., Phoma glomerata and septoria sp.
b) Fungi associated with die-back: Coniothyrium pini, Pleospora sp.
and Sphoeropsis sabinae.In addition, leaves followed by die back.
These symptoms are accompanied with black mycelial threads in the pith region.
The disease was severe on l0-25oh and mild on over 50% of the trees.
In the laboratory, 12 fungi were isolated and there morphology, colony shape and pathogenicity characteristics were evaluated.
It was possible to group these fungi in two categories: a) Fungi associated with leaf blight Alternaria identification of the black mycelial threads in the pith region revealed the presence of the fungus Neocosmospora sp.
