The course covers the main causes of damage of forest trees by abiotic stress (thermal, water, pollution) and biotic due to fungi, oomycetes, bacteria, viruses. Will be illustrate Koch's postulates, the concepts of parasitism, pathogenicity and virulence, the infectious cycle, the plant-pathogen interactions, disease resistance, epidemiology, diagnosis and struggle. The main diseases of forest trees in forest plantations and nurseries will be illustrated.

The course covers:
- the main causes of damage of forest plants to abiotic (thermal stress, water, pollution) and biotic due to fungi, oomycetes, bacteria and viruses.
- -discusses the concepts of parasitism, pathogenicity (Koch's postulates) and virulence, the infectious cycle, the plant-pathogen interactions, disease resistance, epidemiology, diagnosis and struggle.
- -describes the main diseases of forest trees in the Alps and the Mediterranean, and particularly those that affect the foliage (defoliation, dieback and rusts), the stem (agents of canker, wilt and decay), the root system (rot and boot rot decay).
The course focuses on the ecological and biological characteristics of pathogenic microorganisms and their interaction with plants.
