Gray mold, caused by Botrytis cinerea, is the primary factor contributing to postharvest losses in table grape fruit. In this study, we have identified amphotericin B (AMB), a natural compound originating from Streptomyces nodosus, as promising agent managing gray mold grapes. vitro experiments demonstrated that 0.2 mg/L AMB achieved an inhibition rate of over 90% against B. cinerea PDA medium, and vivo assays on berries showed 200 treatment could completely suppress occurrence disease. A mechanism analysis found disrupted plasma membrane structure, which consequently triggered cellular leakage induced cell death. Furthermore, application effectively modulated transcriptional profile genes related redox homeostasis, transmembrane transport, peroxidase functions thereby reducing virulence fungus. addition, had potential activate defense mechanisms grapes enhancing activities ROS-scavenging enzymes defense-associated enzymes. Collectively, can be regarded antifungal combats extending shelf life

Phytophthora capsici is a phytopathogen that affects postharvest bell peppers, as it causes rotting and decreases their commercial value. This study evaluates the efficacy of chitosan biocontrol agent against P. on peppers using in vitro vivo assays. The antifungal activity was evaluated at four concentrations (0.5, 1.0, 1.5, 2.0 g L−1). Its effect mycelial growth inhibition, sporangial germination, disease incidence severity, fruit weight loss determined. results show 1.0 L−1 or higher completely inhibited germination reduced severity to 0% treated fruit. Furthermore, treatments preserved fresh dry fruit, which prevented deterioration. demonstrates an effective environmentally friendly alternative for management diseases peppers. could reduce consumer dependence synthetic fungicides preserve quality.
