AB Phytophthora cinnamomi, responsible for “root rot” or “dieback” plant disease, causesa significant amount of economic and environmental impact. In this work, the fungicide action ofnanocomposites based on silver nanoparticles and polyphenol inclusion compounds, which featureenhanced bioavailability and water solubility, was assayed for the control of this soil-borne watermold. Inclusion compounds were prepared by an aqueous two-phase system separation methodthrough extraction, either in an hydroalcoholic solution with chitosan oligomers (COS) or in a cholinechloride:urea:glycerol deep eutectic solvent (DES). The new inclusion compounds were synthesizedfrom 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 responseagainst Phytophthora cinnamomi isolate MYC43 (at concentrations of 125, 250 and 500 μg·mL−1) wastested, which found a significant mycelial growth inhibition, particularly high for the compositesprepared using DES. Therefore, these nanocomposites hold promise as an alternative to fosetyl-Aland metalaxyl conventional systemic fungicides.
