Bioformulation of Microbial Biocontrol Agents for a Sustainable Agriculture

Abstract

AbstractThe application of microbial based biopesticides has become a sustainable alternative to the use of chemicals to prevent yield losses due to plant pathogens. However, microbial based biopesticides are often unsuccessfully formulated and do not meet the demanding regulatory standards required by the agencies, which hinders their commercialization. Hence, an outline on the approaches to attain more effective formulations might be useful for the development of future more effective products.With this aim, this chapter reports the current state of biocontrol strategies and describes the principles of microbial biocontrol formulations. Emphasis is placed on techniques and tools available for the development and characterisation of microbial products. To provide glimpses on the possible formulations, the different existing additives, carriers, inoculation techniques and formulation types are exhaustively reviewed. Finally, requirements and principles for efficacy evaluation of plant protection products in the European Union are included (see Chaps. 10.1007/978-3-030-53238-3_11, 10.1007/978-3-030-53238-3_18 and 10.1007/978-3-030-53238-3_19).
