Because of this susceptibility, infectivity of these plants might occur if contacted by drift or other off-target dispersal of bacterial inoculum from field application of this pathogen used for biological weed control.
Thus, as with field-scale application of herbicides and other compounds that alter plant growth, biological control agents should be applied using proper safeguards to protect non-target species.
We did not examine any of the plants in our host range experiments for bacterial colonisation, but this could perhaps be the subject of future investigations.
