Aims: To investigate the potential of Pantoea agglomerans to control the major post‐harvest diseases on Golden Delicious apples. Methods and Results: In laboratory trials, a high level of control of Penicillium expansum , Botrytis cinerea and Rhizopus stolonifer was obtained with P. agglomerans . In semi‐commercial trials at 1°C in air and a low oxygen atmosphere, the reduction of blue mould was 81% and 100%, respectively, and control of grey mould was achieved equally with P. agglomerans and imazalil. In trials at 1°C and seven atmosphere conditions, maximum reduction in decay was 80% obtained at 3% O 2 –6% CO 2 . The population of P. agglomerans on apples followed the same pattern under all three atmosphere conditions studied. Conclusions:Pantoea agglomerans could be used effectively on apples under a wide range of temperature and atmosphere conditions. Significance and Impact of the Study:Pantoea agglomerans can be used as a biocontrol agent on apples at 8 × 10 7 cfu ml –1 , the same concentration as in pears. This will facilitate the application of this biological control agent by the growers in packing houses.
