Attacks of necrotrophic and biotrophic fungi affect a large number of crops worldwide and are difficult to control
with fungicides due to their genetic plasticity. Encapsulation technology is a good alternative for controlling
fungal diseases. In this work, encapsulated samples of salicylic acid (SA) with silica (Si:SA) or chitosan (Ch:SA) at
three different ratios were prepared by spray drying, and morphological and physicochemical characterised.
Therefore, size distribution, specific surface area, thermal stability, encapsulation efficiency, and in-vitro SA
release were determined. Biological activity of encapsulated samples were tested against different fungi of
agricultural interest at various concentrations (0–1000 µM). Treatments prepared with the lowest ratios for both
capsules, were found to have the best antifungal effect in an in vitro system, inhibiting the mycelial growth of
Alternaria alternata, Botrytis cinerea, Fusarium oxysporum and Geotrichum candidum. Similarly, treatments
with the lowest ratios of both encapsulated samples reduced free SA toxicity on Arabidopsis thaliana seeds. In
this system, plants treated with capsules had higher root and rosette development than those treated with free
SA. In conclusion, a product with a great potential in agriculture that shows high antifungal capacity and low
toxicity for plants have been developed through a controlled and industrially viable process. [-]
