Multifunctional products based on biocontrol agents from microbiome: new solution to control postharvest diseases

Abstract: Postharvest biocontrol as a viable alternative to the use of synthetic chemicals has
been the focus of scientists and some commercial companies during the last 30 years. However, although successful results have been obtained at laboratory and commercial assays, the number of products in the market is scarce. Different approaches, whether used individually or in combination, are proposed in this presentation in order to achieve the objective of having new tools based on biocontrol agents available and with good efficacy. The first one is the host microbiome knowledge as a promising source of potential biocontrol agents adapted to specific environments. The second strategy consists in combining isolates from different environments into microbial consortia to enhance the final product’s biocontrol resilience and stability under varying conditions that may occur in the field. The third one is to develop multifunctional products that address not only disease control but also physiological disorders, thereby improving the overall quality of fruit. Finally, an adequate process of production and formulation of microorganisms and all the other components is necessary to ensure the development of competitive and effective products.
