The yeasts Trichosporon pullulans, Cryptococcus laurentii and Rhodotorula glutinis were sprayed at a concentration of 1×108 CFU/ml o­nto sweet cherry fruit in two orchards prior to harvest. Survival of these species o­n fruit surfaces under field conditions was investigated. Also, their biocontrol efficacy against postharvest decay of cherry fruit stored under various conditions was assessed. All three yeasts colonized the surface of sweet cherry fruit. However, o­nly C. laurentii and R. glutinis maintained populations at high and stable levels throughout the 4-day experiment period. C. laurentii was the most effective and promising of the three antagonists. It had strong survival ability o­n fruit surfaces under field conditions, and adaptability to postharvest storage conditions of low temperature, low O₂ and high CO₂ concentrations.
