In this work, the fungicide action of nanocomposites based on silver nanoparticles and polyphenol inclusion compounds, which feature enhanced bioavailability and water solubility, was assayed for the control of this soil-borne water mold. Inclusion compounds were prepared by an aqueous two-phase system separation method through extraction, either in an hydroalcoholic solution with chitosan oligomers (COS) or in a choline chloride:urea:glycerol deep eutectic solvent (DES). The new inclusion compounds were synthesized from stevioside and various polyphenols (gallic acid, silymarin, ferulic acid and curcumin), in a [6:1] ratio in the COS medium and in a [3:1] ratio in the DES medium, respectively. Their in vitro response against Phytophthora cinnamomi isolate MYC43 (at concentrations of 125, 250 and 500 µg·mL-1) was tested, which found a significant mycelial growth inhibition, particularly high for the composites prepared using DES. Therefore, these nanocomposites hold promise as an alternative to fosetyl-Al and metalaxyl conventional systemic fungicides. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.121 2018 Biochemistry 2018 Q1 Infectious Diseases 2018 Q1 Pharmacology, Toxicology and Pharmaceutics (miscellaneous) 2018 Q1 Microbiology (medical) 2018 Q1 Pharmacology (medical) 2018 Q1 Microbiology 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martín Gil, Jesús Iacomi, Beatrice Michaela Pérez Lebeña, Eduardo Barrio Arredondo, María Teresa (orcid)0000-0003-2713-2786 Martín Ramos, Pablo Universidad de Zaragoza 5011 500 Universidad de Zaragoza Dpto.
