BIOLOGICAL CONTROL OF POSTHARVEST DISEASES OF APPLES AND PEARS |
| Author: | J. Kampp |
| Abstract:
Bacteria and yeast isolates were tested as biocontrol agents against Botrytis cinerea (Pers.) and Penicillium expansum (Link) 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 temperatures and also reduced rotting at higher temperatures. The efficiency of the two antagonists was lower when they were tested against the pathogens on pears. Although strain A-5 produced antibiotic metabolites invitro, 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. | |
