An integrated approach was studied for the control of postharvest diseases of peaches including application of a yeast antagonist (Candida oleophila), hot water treatment at 55 °C for 10 s, and storage in modified atmosphere at 0 °C. We evaluated the efficacy of all three tactics, both as stand-alone treatments and in combination. Hot water and yeast antagonist as stand-alone treatments were not effective in controlling Botrytis cinerea and Penicillium expansum infections on wound-inoculated peaches. In contrast, modified atmosphere packaging alone significantly reduced lesion diameters caused by the infections of both pathogens after 45 days storage at 0 °C and 5 days at 24 °C. The biocontrol activity of yeast antagonist was improved when yeast treatment was combined with modified atmosphere packaging. The results also indicate that all of the treatments significantly reduced the decay incidence caused by natural infections after 45 days of storage at 0 °C followed by 5 days at 24 °C. The highest efficacy was achieved by the combination of all three tactics. None of the treatments caused surface damage to fruits or impaired quality.
