Learning outcomes

Students will acquire basic knowledge about plant-pathogen interactions, pathogenicity and virulence mechanisms, and plant responses to pathogens.
At the end of the Course, students will have specific competences on diagnosis, prevention and therapy of grapevine diseases, according to modern measures of crop management and environment protection.
