In the study presented herein, the enhancement of the antifungal activity against this pathogen, resulting from the addition of silver nanoparticles (AgNPs) to different polyphenol-stevioside inclusion compounds, dispersed either in a chitosan oligomers hydroalcoholic solution or in a choline chloride:urea:glycerol deep eutectic solvent, was investigated in vitro. The polyphenols assayed were curcumin, ferulic acid, gallic acid and silymarin. Four composite concentrations (62.5, 125, 250 and 500 µg·mL−1), with and without AgNPs, were assessed, finding noticeable differences in mycelial growth inhibition, with EC50 and EC90 values ranging from 118 to 579 µg·mL−1 and from 333 to 2604 µg·mL−1, respectively. The obtained results evidenced the improved efficacy of the composites with AgNPs, a superior performance of the composites based on curcumin and ferulic acid, and the advantages of the deep eutectic solvent-based dispersion medium over the chitosan oligomers-based one. The reported composites hold promise for crop protection applications. application/pdf eng MDPI info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2018 The Authors
