Learning outcomes and their assessment

Students obtain the knowledge about the reasons of plant diseases and know the classification of diseases and the peculiarities of diseases caused by bacteria and viruses – 1st test.
Students comprehend the concept of resistance, understand the peculiarities of disease development and know the methods of disease assessment and diagnostics. They can characterise the most important phyla of the kingdoms Fungi, Chromista and Protozoa – 2nd test.
Students can diagnose diseases and identify their causal agents till genus level – laboratory exercises and a practical test.
Students know the most important plant diseases, can evaluate their harmfulness and integrate the knowledge about disease life cycles with the factors promoting their development, with agronomic practice and with possibilities of disease control – 3rd and 4th test.
