Megjegyzések:	The research work has been carried out at the Látókép Research Site of the University of Debrecen, Centre for Agricultural Sciences, Farm and Regional Research Institute on calcareous chernozem soil in. We examined the effects of sowing times and the fungicide treatments on the phytopathogenic characteristics phytopathological properties of sunflower hybrids. In order to characterize the phytopathological properties of sunflower hybrids in a complex way infection index (Ii) has been elaborated. The infection of sunflower populations by fungal phytopathogenes was mainly determined by the weather conditions of the crop year. The development of infection indexes depended mainly on the sowing time in the studied crop years (r=-0.806, r=-0.755). Fungicide application had significant contribution to the moderation of the unfavourable effect of sowing time in both years and thus it decreased the infection index of sunflower populations (r=-0.464, r=-0.578). Plant phytopathogenes resulted in significant yield loss in sunflower populations only in the crop year of 2012 that was characterized by heavy infection.
