A selection strategy for microbial antagonists to control postharvest diseases of fruits and vegetables.

Fruit wounds were utilized to screen unidentified microbial populations on fruit surfaces for potential antagonists to postharvest rot organisms. Washings from apple, oranges and tomato fruit surfaces were placed in fresh apple fruit wounds which were subsequently challenged with postharvest rot pathogens. After 10 d, those wounds not showing rot development were scraped with a sterile needle. Dislodged material was diluted in sterile water which was diluted serially and plated on nutrient agar. Individual isolations were made from frequently occurring colonies and tested for antagonistic activity against postharvest pathogens. Using these procedures, 6 isolates were identified which were effective antagonists against apple rots caused by Botrytis cinerea and Penicillium expansum. Three of the isolates were identified as Candida sake and 1 as C. tenuis, neither of which has been previously described as a biocontrol agent.
