AbstractDiseases and abiotic damage influence the use and maintenance of forest ecosystems, tree populations and individual trees. This course provides a basic overview of important infectious diseases and abiotic damage in woody plants, with a focus on Central Europe.
ObjectiveStudents are able to
- describe the basic processes of pathogenesis in trees.
- explain methods of disease diagnosis and control.
- name and identify ecologically or economically significant tree and forest diseases.
ContentThe concept of 'Forest Health', history of forest pathology, environment and disease, pathogenesis and defence, basics of epidemiology, Principles of tree management. Morphology, biology, diagnosis and control of selected pathogens (parasitic phanerogams, fungi, bacteria, viruses and viroids). Morphology of mycorrhiza. Damages to woody plants caused by abiotic environmental factors.
Lecture notesLecture slides are avilable in electronic form.
