ABSTRACT
Bacteria and yeast isolates were tested as biocontrol agents of Botrytis cinerea and Penicillium expansum on apples and pears. A bacterium Erwinia sp. strain A-5, provided complete protection against B. cinerea on apples. A yeast, Rhodotorula strain A-60 was effective against P. expansum at low temp. and also reduced rotting at higher temp. The efficiency of the 2 antagonists was lower when they were tested against the pathogens on pears. Although strain A-5 produced antibiotic metabolites in vitro, it was not possible to demonstrate the role of these metabolites in biocontrol on the fruit. Growth rate experiments were conducted with the antagonists in order to optimise conditions for biocontrol activity.
