“…In addition, the FT-IR spectroscopy result of the produced Cu/Cu 2 O nanocomposite is presented in Figure c. A strong band at 630 cm –1 was identified owing to the vibrations of the Cu–O functional group, and a band at 1095 cm –1 is linked to the existence of oxygen bonding in copper, confirming the creation of Cu 2 O NPs, similar to previous reports. , The presence of the carboxylic acid group may be confirmed by the other absorption band at 1200 cm –1 . The CO stretching of the ketone group was reflected by the peak at 1600 cm –1 .…”

The synthesis of fungicides in eco-friendly and costeffective ways is significantly essential for agriculture. Plant pathogenic fungi cause many ecological and economic issues worldwide, which must be treated with effective fungicides. Here, this study proposes the biosynthesis of fungicides, which combines copper and Cu 2 O nanoparticles (Cu/Cu 2 O) synthesized using durian shell (DS) extract as a reducing agent in aqueous media. Sugar and polyphenol compounds contained in DS, as the main phytochemicals acting in the reduction procedure, were extracted under different temperatures and duration conditions to obtain the highest yields. We confirmed the extraction process performed at 70 °C for 60 min to be the most effective in extracting sugar (6.1 g/L) and polyphenols (22.7 mg/L). We determined the suitable conditions for Cu/Cu 2 O synthesis using a DS extract as a reducing agent for a synthesis time of 90 min, a volume ratio of DR extract/Cu 2+ of 15:35, an initial pH solution of 10, a synthesis temperature of 70 °C, and a CuSO 4 concentration of 10 mM. The characterization results of as-prepared Cu/Cu 2 O NP showed a highly crystalline structure of Cu 2 O and Cu with sizes estimated in the range of 40−25 nm and 25−30 nm, respectively. Through in vitro experiments, the antifungal efficacy of Cu/Cu 2 O against Corynespora cassiicola and Neoscytalidium dimidiatum was investigated by the inhibition zone. The green-synthesized Cu/Cu 2 O nanocomposites, which are potential antifungals against plant pathogens, exhibited excellent antifungal efficacy against both Corynespora cassiicola (MIC = 0.25 g/L, the diameter of the inhibition zone was 22.00 ± 0.52 mm) and Neoscytalidium dimidiatum (MIC = 0.0625 g/L, the diameter of the inhibition zone was 18.00 ± 0.58 mm). Cu/Cu 2 O nanocomosites prepared in this study could be a valuable suggestion for the control of plant pathogenic fungi affecting crop species globally.
