Learning outcomes

Students will acquire a basic knowledge on main plant diseases and specific knowledge about grapevine disease agents; students will also acquire the necessary technical and regulatory informations for the correct management of disease control in the vineyard.


Introduction to plant pathology
History of Plant Pathology, scientific and economic relevance of plant pathology.
Terminology: Parasitism and Pathogenicity, Host Range of Pathogens, Stages in the Development of Disease, The Disease Cycle
Classification of the main classes of phytopathogens (taxonomy)
Diseases caused by phytopathogenic fungi and fungal-like organisms
General features of phytopathogenic fungi
Taxonomy and classification
The infection process
Pathogenicity factors: lytic enzymes, phytotoxins, hormones, research for fungal pathogenicity factors.
Diseases caused by phytopathogenic procariotes
General features of phytopathogenic procariotes (bacteria and phytoplasmas)
Taxonomy and classification
The infection process
Pathogenicity factors: lytic enzymes, phytotoxins, hormones, LPSs, research for bacterial pathogenicity factors.
Diseases caused by phytopathogenic viruses and viroids
General features of phytopathogenic viruses
Taxonomy and classification
The infection process: transmission, replication, movement.
Viroids: transmission, replication.
