Many fungal diseases on wheat are responsible for yield loss and besides increasing production cost due to the fungicide application. Many pathogens are seedborne and play an important role in disease epidemiology. The present work was carried out to verify the effect of nitrogen rates and propiconazole application on fungal disease severity and seed health of two wheat cultivars, 'IAC-24' and 'IAC-60'. The results showed a polinomial effect of N rates on the severity of Bipolaris sorokiniana on leaves and a linear effect on seeds, in the absence of fungicide application, for both cultivars.
