Three winter wheat cultivars, PKB-Lepoklasa, Jugoslavija and Francuska, were differently susceptible to Fusarium spp., widely used in the production and processing, were selected for the experiment. Three treatments were applied to these cultivars: the artificial inoculation with the isolates Fusarium spp., wheat protection with the fungicide on the basis of active ingredients of flutriafol and carbendasim (85 + 135 g/l) where the spontaneous infection in different wheat pheno-phases is monitored. The same cultivar from the same location did not include in the experiment. Experiments were performed three years. Phytopatologic estimate were two times during the period of vegetation. During three years of researching PKB Lepoklasa had 100% infected plants with fungi Fusarium spp., while cultivar Jugoslavija 85%, Francuska 65%. The presence of fungi resulted the reduced germination, as mycotoxins inhibited the proteins synthesis. The development of fungi in wheat plants resulted grain wilt due to the damage of burial procession. The fungi of the genus Fusarium spp. produce many mycotoxins, while the presence of trichothecene type B-deoxynivalenol. Moreover, zearalenone and fumonisin were determined.
