Kloeckera apiculata strain (34-9) to control Botrytis cinerea during the pre- and postharvest handling of strawberries

The efficacy ofKloeckera apiculata strain (34-9) in controlling gray mould (Botrytis cinerea) of strawberry fruit was evaluated in pre- and postharvest handling. Dynamic growth ofK. apiculata strain (34-9) was tested in the field on strawberry. Antagonist population was 2.2×106 CFU/ml in strawberry fruit after it was treated 2 h in the field, then decreased slightly, and then the population stabilized at the concentration 105 CFU/ml during the period of strawberry growth. The effect ofK. apiculata strain (34-9) (1.0×108 CFU/ml) onB. cinerea was evaluated. Preharvest (34-9) treatment was the most effective, while postharvest (34-9) and Sumilex treatment equally reduced the incidence of decay, caused by gray moulds (B. cinerea). Light microscopy revealed attachment of the yeast cells to the pathogen hyphae.Kloeckera apiculata strain (34-9) did not alter any quality parameters of fruit when assessed at the end of storage.
