The analyses of the results after four years of research (2006-2009),which included continuous examimation of fi eld symptoms and laboratoryanalyses,have shown the presence of Mycosphaerella graminicola, causer ofSeptoria tritici grey blotches on wheat (Triticum aestivum L.).The fi eld analyses of the Pelagonia, Probistip, Skopje, Resen and Kocaniregion,have shown that the symptoms occur during the entire wheat vegetationperiod , especialy on the wheat leaves.The damages caused by these fungi can range from minimal to almosttotal loss of a the crop. The intensity of the disease depends entirely on the timewhen it occurs and on the weather conditions.Generally, areas with more frequent rainfall have increased levels of thedisease.The results from the laboratory analysis of our ascomycete samples,were compared with previously published data using numerous microscopeobservations of the morphological characteristics.
