The BIOFLORA project was born from the interest detected in both producing companies, distributors and consumers, in promoting crop management systems that are more sustainable and respectful of the environment. This interest links with the philosophy that permeates the European Green Deal, which establishes the European Biodiversity strategy that defends sustainable agricultural production systems based on biodiversity and sets the objective that in 2030 at least 25% of the SAU is certified. in organic production. Our project will work, supporting outdoor tomato production systems where different strategies will be tested to reduce the incidence of viruses in this outdoor crop through the use of floral bands associated with the crop and the use of a biostimulant, responding to one of the great challenges that this outdoor crop currently has and that is causing significant losses in the production sector, leading in many cases to the abandonment of this star crop in the summer season. The present project aims to obtain a proposal for the composition of floral bands adapted to the environmental and productive conditions of outdoor tomato cultivation in the province of Malaga using botanical species better adapted to the productive environment and that can help harbor predators of the main vector agents transmitting the viruses that affect this crop, combined with the application of a biostimulant that improves the response capacity of the crop against viruses and other possible plant diseases, therefore it is about testing a double strategy to favor the biodiversity of the ecosystem and the response capacity of the plant. In addition, the effects of Chitosan on the incidence of viruses in tomato plants will be analyzed.
