The use of antagonistic microorganisms represent a promising strategy to control fruit pathogens. The project is based on the study of bacterial Biological Control Agents (BCAs) against Botrytis bunch rot of grapes. The objectives will be: 1) to develop recommendations for vineyard applications of bacterial BCAs based on a BBR disease risk model, 2) to develop formulations with natural products for field applications; 3) to examine the effect of BCA applications on berry microbiota. Methodologies used involve different plant science areas and include classic microbiology, epidemics modelling and molecular footprint techniques. The results may have direct impact on the wine and viticulture sector.
I obtained a PhD in Food and Agriculture Science and Technology by the University of Lleida (Spain) and IRTA (Catalan Institute for Research & Technology in Food & Agriculture; Spain). My research project aimed to study the efficacy of alternative strategies to synthetic fungicides to control of Botrytis bunch rot (Botrytis cinerea) in organic wine grapes. I also investigated the B. cinerea epidemiology and the survival of Biological Control Agents (BCAs) under abiotic factors and sour rot of grapes. My AgreenSkills post-doc fellowship was carried out at UMR SAVE within the project entitled “Biocontrol strategies against Botrytis rot of grapes based on disease risk indicators and developing bacterial Biological Control Agents". This project was funded by INRA and the Inter-professional Council of Bordeaux Wine (CIVB). This project enlarged my background with the use of metagenomic analysis of microbial communities, as well as disease risk modelling and decision support systems. Significant results have been obtained regarding efficacy of novel bacterial BCAs against Botrytis bunch rot of grapes in the field, as well as testing registered products. The amount of results obtained during these 2 years fellowship has been included in several publications already published or currently in progress. My AgreenSkills fellowship experience has also raised the opportunity to have a renewed post-doc position at UMR SAVE. This position has nearly full time dedication to the European SUDOE project “VINOVERT” (https://vinovert.eu/en/), a research project in a close partnership among viticulture, pathology, oenology and economy research groups from France, Spain and Portugal.
