Learning unit contents
This module focuses on the knowledge of weeds, pathogens and pests, their cycle, their epidemiology and their diagnosis. The course provides students with knowledge of the biology of various bio-aggressors (pathogens, pests, disease vectors for plants, animals or humans, regulated organisms), parasitic plants and weeds. The course presents the interactions of pests with their hosts and the environment (climatic and biotic factors such as chemical messages, host-disease interactions or plant-pest-insects, etc.). It sets out the elements of making it possible to make the link between their biological cycle and their epidemiology. The principle of predictive and warning models for risk assessment and pest management is outlined. The approach to be adopted for diagnosis (sampling, monitoring, identification and diagnosis techniques) is studied and illustrated by case studies and practical work including identification of all types of bio-agressors. Finally, the course presents, through the practical case study, the steps of the intervention approach for the prevention, control or elimination of bio-aggressors as well as the main elements to be included in the choice of methods of treatment. intervention (agronomic context, biological and ecological constraints, regulatory and socio-economic constraints).
Learning outcomes of the learning unit
At the end of this module, the student will have demonstrated his ability to use in practical activities and to return during the final examination:
* Knowledge of biology and/or ability to identify major groups of bio-aggressors (pests, vectors, diseases and weeds) and the nature of plant/pest/ beneficial insects / environmental interactions
* His knowledge of the different stages of the epidemiological cycle
* His knowledge of the conditions favoring the development of bio-aggressors * His understanding of the notions of damage threshold and economic threshold of intervention
* His understanding of prediction and warning models
* Understanding of the intervention approach and considerations for choosing a method or combination of intervention methods
In particular, he must be able to:
* Identify the main categories of pests, pathogens and weeds
* Explain how to make a diagnosis using the main techniques
* To analyze the course of an epidemic, to identify the sensitive stages of the host and the key stages of intervention
* To analyze the biological, regulatory and socio-economic constraints that affect the choice of effective intervention methods for the prevention, control or elimination of weeds and bio-aggressors
Prerequisite knowledge and skills
* Bases in Biology, Botany, Microbiology, Plant Physiology and Entomology
* English language
Planned learning activities and teaching methods
* Theoretical lectures (ex-cathedra or online course)
* Practical laboratory work: identification of various pests (pests, weeds, pathogens):
o Inoculation of phytopathogenic agents and observation of symptoms
o Microscopic observation to identify phytopathogenic agents
o Use of insect and pest identification keys and weeds
o Observation and identification in the field (2h)
* Personal work to be done:
o Constitution of a herbarium of diseased plants
o Search for information and documentation (interview of a farmer, search on the internet and other sources)
* Group work including an oral presentation and a poster (in English): application of the theoretical elements presented to case studies (data integration, synthesis)
* Preparation of the individual final evaluation during an oral and collegial examination
