Botrytis cinerea, a phytopathogen agent that causes gray mold disease, could provoke alterations in postharvest strawberry and blueberry fruits and consequently reduce its shelf-life. Habitual application of fungicides may cause resistance due to its genetic plasticity, with the corresponding serious environmental damage. This research aimed to investigate the effect of ozone and pulsed light (PL) treatments, applied individually or in combination, on Botrytis cinerea in peptone water, as environmentally friendly alternatives to synthetic fungicides. A Weibull type distribution of resistance model was applied to characterize inactivation kinetics.
