The evolution of agriculture is facing strong societal expectations. One of them is to drastically reduce the use of synthetic inputs and in particular of plant protection products (PPP). In response, farmers and professionals in charge of agricultural development must invent a so-called "agroecological" agriculture, by ensuring profitability and sustainability of production systems and by implementing a combination of many levers. The BESTIM network is part of this logic and proposes the concept of "agroecological immunity" which aims to optimize the stimulation of plant health in efficient agroecological systems. We’ve adapted the concept of ecological immunity initially described in the animal system (Sadd and Schmid-Hempel, 2009; Schulenburg et al., 2009), to the plant system placed in an agroecological context. Plant health is to be understood here in a broad sense. It covers all the physiological mechanisms that ensure the expression of an efficient immune system that protects the plant from pests and diseases while guaranteeing optimal development (yield, quality) and taking into account its environment (microbiota, abiotic stresses). The objective of the BESTIM network is not limited to understanding the physiological mechanisms involved in the application of different levers, alone or in combination, that impact immunity. It aims, during the 5 years of the approval period (2021 - 2025), to transfer this knowledge from the laboratory to the field and to associate it with other alternative levers already available or being developed to achieve redesigned cropping systems tending towards "low inputs". The RMT BESTIM brings together many organizations wishing to engage collectively in this agroecological immunity approach: Research institute, universities, Grandes Ecoles, agricultural Highschool, Technical Institute, R&D centers, Producers associations….
