The aim of this study was to evaluate the development of wheat leaf diseases depending on fungicide treatment. A two-factorial field experiment (A – fungicide treatment (five schemes, including control without fungicide); B – the level of nitrogen fertilization (four levels)) with four replications was carried out in 2019. Disease development during the whole vegetation season was evaluated by calculating the area under the disease progress stairs (AUDPS); and the two-factor dispersion analysis was used to determine the significance of data. Tan spot and Septoria leaf blotch were the most important diseases. The level of nitrogen did not influence the development of leaf diseases; however, the impact of fungicides was significant. All the used fungicide treatment schemes decreased severity of diseases, but differences between variants were not essential in 2019.
