Protecting crops against pest attacks is a major challenge now that reducing pesticide use is a priority in ecological, economic and health terms. It is also one of the foundations of sustainable agriculture.
The unit aims to optimize crop resistance to pests, on a gene, genotype or plant stand scale, by analysing the range of resistance genes and the mechanisms that govern that resistance, including those linked to its circumvention. Its teams work on four main lines of research: identifying and characterizing sources of resistance; studying the mechanisms of these types of resistance and of their circumvention; developing strategies for managing and using these types of resistance; and assessing and improving the sustainability of resistance.
