FOOD PATHOLOGY AND PARASITOLOGY
Module POSTHARVEST PATHOLOGY OF PLANT PRODUCTS

Academic Year 2024/2025 - Teacher: ALESSANDRO VITALE

Expected Learning Outcomes

a. Knowledge and understanding: the course aims to provide students with basic knowledge on the main biotic and abioticalterations of post-harvest plant products, on their identification and diagnosis and on the control and prevention of contaminationby phytopathogens and mycotoxins affecting quality and the quantity of vegetables post-harvest and in storage.

b. Applied knowledge and understanding: through the acquisition of knowledge on the main biotic and abiotic alterations, onthe most up-to-date biological and integrated diagnosis and control methodologies, the student will acquire the ability to plan themost appropriate strategies to be used in post-harvest

c. Autonomy of judgment: through attendance of lectures, exercises and seminars, students will acquire full autonomy inchoosing the most effective and up-to-date post-harvest disease prevention and control strategies

d. Communication skills: reading scientific articles, participation in seminars, in-depth study of specific themes through groupactivities and the presentation of the results obtained will allow students to develop correct technical-scientific terminology in thefield of postharvest plant pathology, and an adequate ability to explain the topics learned.

e. Ability to learn: the course will contribute to the development of the ability to understand and critically analyze the topics boththrough group work and independently, to the analysis of scientific results and to the preparation of the thesis, thus preparing thestudent for its future activity in the field of technical consultancy in the agri-food sector.

Course Structure

The course is carried out through lectures and exercises in the classroom and in the laboratory. In detail, the undersigned will conduct theoretical lessons for 1 CFU (equivalent to 14 hours) of practical activities (classroom and laboratory exercises, educational visits, seminars, etc.) among those planned by the course.

Discussions on case studies are also planned. If the conditions require it, the lessons will be held online, and the exercises and field visits will be replaced byexercises and technical visits online.

Information for students with disabilities and/or DSA. As a guarantee of equal opportunities and in compliance with currentlaws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures,based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contact of CInAP (Center for Active and Participatory Inclusion - Services for Disabilities and/or DSAs), in the person of professor Anna DeAngelis.

Required Prerequisites

Basic knowledge of microbiology and plant biology

Attendance of Lessons

Attendance is not compulsory, but it is strongly recommended Attendance at lessons is not mandatory to take the exam.

Learning Assessment

Learning Assessment Procedures

The exam consists of an individual oral interview and tests the ability to reason and connect the knowledges acquired.

Elementsof evaluation will be the relevance of the answers to the questions asked, the quality of the contents, the ability to connect withother topics covered by the program, the ability to provide examples, the ownership of technical language and the overallexpressive ability of the student.
