Actinobacteria, as they are called, were isolated from healthy crops by a research team incorporating CSIRO and Flinders University (SA) experts to monitor their effect on plant growth when applied at sowing. More than 30" of the actinobacteria strains were active against important root diseases, with the most effective reducing Take-all symptom levels by 60" and Pythium symptoms by more than 80". Importantly, these results were not limited to the laboratory or the glasshouse. Associate Professor Chris Franco of Flinders University believes actinobacteria have succeeded in the field, where other biological agents fail, because they colonize internal plant tissues.
