Winter wheat and winter barley were grown on soil contaminated with different bacterial potato pathogen Erwinia carotovora subsp. atroseptica (Eca) from a previous blackleg-infected potato crop. Disease caused by Septoria tritici was greater on the high level contamination areas than the low level areas. Rhynchosporium secalis infection on barley was not affected overall, although it decreased on the high level contamination areas early in the season. The Eca strain (SCRI1039) carrying a streptomycin marker was detected on the upper foliage of the wheat and barley. The increased S. tritici symptoms were thought to be due to 'synergistic' interactions between the Eca and the fungal mycelium reported in previous laboratory experiments
