Objectives

Students are expected to know the main pests of crops, including pests, diseases and weeds. Know the general characteristics of fungi causal agents of plant diseases, the way they infect, invade, reproduce and spread in the host plant. Know the main insects and acari of crops, know how to classify an insect (to order) and how to identify the species. Know how to relate damage (symptoms and signs) in plants with causal agents. Know control methdos including cultural, biological, biotechnical and chemical methods, namely those used in Portugal. Acquire diagnostic skills of phytosanitary problems in various plants

Learning outcomes and competences

Know the main groups of living beings that are pests and causal agents of plant diseases. Know how to make the diagnosis and outline a protection plan including preventive and curative control methods. Write a technical report, discuss a topic and make an oral presentation.

Program

1. Introduction: Plant protection in sustainable agriculture modalities. Quarantine pests and diseases (historical cases of attacks that caused high damage, organisms involved, individual liability); Biodiversity in agrarian systems. Relations between living beings in the agrarian ecosystem. National and international organizations related to crop protection. Evolution of plant protection. The pests of crops (key pest, occasional pest; pests, diseases, and weeds). 2. Agricultural Entomology Importance of insects in different ecosystems. Insect morphology. Metamorphoses. Identification until order taxon 3. Agricultural pathology. Importance of fungi in plant protection. Concept of sick plant and healthy plant. Manifestation of the disease (concepts of sign, symptom, symptoms, primary and secondary symptoms). Diagnosis of the disease. Parasite, parasitism, pathogenicity, damage and damage concepts. Tetrahedron of the disease. Disease cycle (inoculation, penetration, infection, invasion, reproduction, spread). Endemic disease. Monocyclic and polycyclic pathogens. Differentiating characteristics of the fungi of the various phylum. Development and reproduction structures. Asexual and sexual reproduction. Asexual and sexual reproduction structures: conidia, oospore, ascospore, basidiospore. Taxonomic classification of fungi. Plant life cycles of the fungus and disease manifestation. 4. Protection strategies in integrated production: Preventive measures of control (types and timing of application); risk assessement; economic threshold level (NEA); examples of NEA; risk maps; harmfulness factors; decision making and choice of control methods. Protection strategies in other production systems. 5. Control methods: cultural and genetic control (use of resistance seeds, exclusion nets, green interventions, greening, solarization, biofumigation). Chemical control (classification of pesticides, modes of action, application, acute and chronic toxicology measures, risks, approval process). Biological control (conservation biological control, classical biological control and treatment Biological control. Predators and parasitoids. Biotechnic control (use of pheromones and other semiochemicals; insect growth regulators, sterile insect control, matting disruption).

Teaching methods and learning activities

The classes of 3.5 hours may be: classroom theory, distance debate (discussion forum), field practice and/or laboratory pratice. There may be a field trip. Classes are at Vairão Campus. On the course page in moodleUP, will be available the documents, work protocols and notices. It will also be the place for the students to submit assigments and where the discussion forum will take place.

Eligibility for exams

Not applicable. The evaluation is carried out during the semestrer without exam or appeal exam.

Calculation formula of final grade

Evaluation formula: Final classification = 50% (Test 1 + Test 2) + 40% (Work 1 + Work 2) + 10% (Oral presentation).
To be approved studante must have at least 10/20.

Examinations or Special Assignments

Special assessment (TE, DA, ...)

Students must try to be present in classes and assessments; however, in the case of student workers or whose status or condition does not allow participation on the day of the face-to-face assessment, an alternative date will be given. This situation does not apply to assyments as they are submitted in moodle.
