Applying knowledge and understanding
At the end of the course, the student will be able to:
1. Apply acquired knowledge regarding plant health and its implication in the crop production chain related to food production.
2. Understand the cause of plant disease, even if not included in the course and define possible actions to mitigate plant health effects.
Making judgements
At the end of the course, the student will be able to:
1. Assess plant products in term of quality (related to plant disease) and safety
Communication skills
At the end of the course, the student will be able to:
1. appropriately utilize the scientific language and the specific lexicon of plant pathology to describe and transfer in oral and written form the acquired concepts.
Learning skills
At the end of the course, the student will be able to:
1.Increase his/her knowledge on Plant health, by self-consultation of specialized texts, scientific and educational journals, also beyond the topics discussed during the lessons
2. Understand the impact of cropping system systems on the quality of plant products.

Teaching methods
The lessons will be held with the support of power point presentations.
Working groups will be organised on plant health topics of interest for the students, mainly on plant health and its impact on selected crop chains.
The course will be integrated with seminars on specific topics relevant for plant health (EFSA expert from Plant Health panel; expert in IPM, entomologist)
Assessment methods and criteria
A diagnostic assessment will be managed at the beginning of the course. It will be managed with oral questions and a general discussion with the students.
Summative assessment will be written. The written examination will contain open questions on the main course topics, both on the general aspects of pests, their impact crop production, quantitative and qualitative aspects, and pest management in different cropping systems, so as on relevant pests in selected value crop chains.
Other information
Lesson frequency is not mandatory, but strongly encouraged.
