Litsea cubeba Essential Oil Reduces Postharvest Blueberry Rot by Inducing Cell Membrane Damage and Reactive Oxygen Species Accumulation in Alternaria alternata

Future Postharvest and Food, EarlyView.
Litsea cubeba essential oil (LCEO) reduces blueberry rot while maintaining quality. It disrupts the cellular structure and membranes of Alternaria alternata, causing solute leakage, while simultaneously inducing reactive oxygen species (ROS) accumulation and mitochondrial membrane potential (MMP) damage in the pathogen.
