This chapter summarizes the state of the art and some key research and innovation perspectives with regard to three topics that are particularly important for biocontrol deployment. The first topic is the use of seeds as targets and/or vectors of biocontrol organisms or substances, enabling seed or plant protection through direct antagonism towards pathogens, plant defence stimulation and manipulation of the seed or plant microbiota. The second topic is formulation of biocontrol organisms and substances, a key activity with high importance to enhance performance of biocontrol products and compatibility with agricultural equipment. The third topic deals with digital tools and agricultural equipment to facilitate the use of biocontrol methods in the field: new equipment tailored for field release of organisms, devices for diagnosing the state of plant, pest or biocontrol agent monitoring, tools for optimizing the positioning and parsimonious use of biocontrol methods, etc.
