TECNICHE FITOSANITARIE PER L'AMBIENTE E IL PAESAGGIOModule ENVIRONMENTAL PLANT PATHOLOGY
Academic Year 2023/2024 - Teacher: Santa Olga CACCIOLAExpected Learning Outcomes
Course Structure
- Environmental Applied Plant Pathology
The course will consist of lectures and laboratory exercises are planned; the activities will include i) the recognition of the main symptoms of plant diseases; ii) learning the main techniques of isolation of fungal pathogens from infected plant tissues. Students are required to participate actively during both the lectures and laboratory activities. Furthermore, students will be asked to prepare a report on a monographic topic chosen with the teacher which will then have to be presented during the lessons as a power point. This will allow students to acquire a series of knowledge related to the following aspects: a) perform a bibliographic research by consulting articles and websites on the chosen topic, taking care to select the most reliable bibliographic sources; b) prepare a report on the basis of a well-drawn outline; c) set up a power point by choosing appropriate images and structuring the slides in an appropriate manner; d) present the talk in public and answer to the questions of the teacher.

Learning Objectives (SKILLS)
- Environmental Applied Plant Pathology
The main objective is to provide the knowledge of plant pathogens, mode of infection, damage, diagnosis and strategies to control diseases of plants in green areas, parks and in natural environments. To provide also theoretical and practical knowledge to plan environmental and landscape protection measures as well as bioremediation strategies in compliance with both phytosanitary legislation and the health of workers and citizens.
AUTONOMY OF JUDGEMENT
Students will be accompanied by the lecturer along a path of knowledge and learning that will enable them to acquire autonomy of judgment through planning theoretical-practical activities, such as analyzing a scientific article and applying laboratory protocols to answer technical questions. They will be posed phytopathological problems (symptomatic plant specimens) that they will have to solve based on the knowledge acquired during the course.
Students'communication skills and capacity for in-depth study
Students' communication skills are an aim of the course. In fact, the lecturer will propose to analyze a scientific publication. Students will have to analyze it and prepare a ppt presentation answering precise analytical questions. This individual study will then be presented in the classroom, and the lecturer will stimulate critical discussion of the data presented. Preparing the report will require honing the skills of learning and capacity for in-depth study knowledge of the proposed topic.
MODE OF VERIFICATION OF LEARNING
· One written mid-course placement test, which will be taken into account for the final assessment
· Written report on an in-depth monograph topic chosen in consultation with the instructor
· Presentation of the report by power point
· During the presentation of the report, the lecturer will ascertain the knowledge gained during the course with some specific questions
EXAMPLES OF FREQUENTLY ASKED QUESTIONS AND/OR EXERCISES
Examples of open-ended questions: Describe the various types of cancers caused by Cryphonectria parasitica. Describe the mechanism of hypovirulence. Illustrate how a phytopathogen is isolated from fruit, leaf and soil
Verification of learning is through a written test and an oral interview (presentation of the paper). Evaluation of the student's preparation will be based on the following criteria: ability to learn and level of depth of the topics covered, properties of synthesis and exposition, and the student's ability to reason.
Grading will follow the following pattern:
Ineligible
Subject knowledge and understanding: Significant deficiencies. Significant inaccuracies
Ability to analyze and synthesize: Irrelevant. Frequent generalizations. Inability to synthesize
Use of references: Completely inappropriate
18-20
Subject knowledge and understanding: At threshold level. Obvious imperfections

Course Structure
The course will consist mostly of lectures, but laboratory exercises are planned for recognizing the main symptoms and learning techniques for isolating fungal pathogens from infected plant tissues.
Students are expected to actively participate both during the course of lectures and during the conduct of laboratory activities. In addition, it will be proposed that students prepare a paper on a monographic topic, chosen in agreement with the lecturer, which is then to be presented in the course of lectures after preparation of a power point. This will enable students to acquire a range of knowledge related to the following aspects: a) conducting a literature search by consulting articles and websites on the chosen topic, taking care to select the most reliable bibliographic sources; b) preparing a paper on the basis of a well-charted outline; c) setting up a power point by choosing appropriate images and structuring the slides appropriately; d) exhibiting in public by answering the lecturer's questions.
Required Prerequisites
- Plant cell biology: structure and function
- General botany: morphology and physiology of plants
- Knowledge of systematic botany
- Elementary knowledge of ecophysiology
Attendance of Lessons
The teaching regulations do not require compulsory attendance; however, in order to take the exam, it is strongly recommended to attend at least 70 percent of the scheduled teaching activities.
The exam requires knowledge of laboratory activities, and participation in these activities is only allowed for students who attend regularly.
