Biosolutions, which include biocontrol solutions, biostimulants and biofertilizers, are considered as levers of interest to help with the agroecological transition of farming systems and to improve their resilience in the face of climate change. However, a number of technical and socio-economical gaps still hamper the use of these biological inputs, particularly in arable farming systems. The aim of the workshop was to consider the conditions that would facilitate the integration of biosolutions into cropping systems and to identify the relevant indicators to be considered to ensure their widespread adoption. It has emerged that while biosolutions are considered as innovative solutions, they have complex modes of action. The challenge is to identify the best conditions that make biosolutions effective, based on field experiments such as the one carried out at the ARVALIS experimental station in Saint Hilaire en Woëvre, France. The effectiveness of these solutions, a key determinant of their adoption, depends on their rational use in combination with other agro-ecological levers. It has also became clear that if these solutions are to be adopted on a large scale, the evaluation of systems including biosolutions must not be based solely on productivity indicators, but must also take into account all the 'co-benefits' associated with these solutions (multi-performance concept).
