Protection des pommes : efficacité des bactéries antagonistes dans l'inhibition de Botrytis cinerea et Penicillium expansum sous atmosphère contrôlée.

Efficacy of antagonistic bacteria in protection of apples against Botrytis cinerea and Penicillium expansum under controlled atmosphere conditions.

Résumé

Of 300 isolates of epiphytic bacteria originating from leaf and fruit surfaces of apple, three were selected which showed very high activity in protection of apples against grey mould (Botrytis cinerea) and blue mould (Penicillium expansum). The bacterial suspension of each isolate was placed on wounds of apples cv. Jonagold followed by inoculation with a conidial suspension of the particular pathogen. Apples were then stored in normal storage at 2-3 °C or in controlled atmosphere. After 40 days, the diameter of the rot spot developed around each wound was measured. The tested bacterial isolates totally protected apples against blue mould in all storage conditions.
