| Abstract:
The strain of Pantoea agglomerans Pa 21889 was isolated as part of a programme to identify potential biological control agents for fire blight from Germany (Steinbrenner, 1991). Pa21889 was first selected for its ability to prevent symptoms of fire blight, in particular production of bacterial ooze, on immature pear fruit inoculated with Erwinia amylovora (Steinbrenner, 1991). Zeller and Wolf in 1996 showed that this strain was also capable of protecting blossoms of Cotoneaster salicifolius from fire blight. Later, Laux et al. (2003) demonstrated that it was also able to significantly reduce the level of fire blight on apple flowers. Those experiments were conducted in an experimental orchard under natural or artificial infection conditions. | |
