The only current treatments for bacterial diseases are copper compounds and antibiotics, both of which have resistance issues. This project demonstrated the proof of concept that bacteriophages can be incorporated into seed treatment polymers, coated on seed and stored for long periods of time without losing activity.
Can bacteriophage be stabilized on seed and used to control bacterial plant diseases?
Due to the Leopold Center shutting down, the project was cut slightly short and did reach the disease control study phase of the project. However, results indicate that bacteriophages can be incorporated into seed treatment polymers, coated on seed and stored for long periods of time without losing activity. The results demonstrated that the developed treatments had no inhibitory effect on germination or vigor. With these results, disease control studies will now be possible. Future studies will determine their effectiveness against bacterial diseases. Stabilization of the treatment on seed was crucial, because newly developed treatments must fit into the industry handling procedures for treatment and storage. This will allow these new bacteriophage treatments to get to market faster without requiring seed conditioning plants to utilize new storage and handling procedures. Similar bacteriophage treatments are now possible against other plant pathogens providing a new biological bactericide with less environmental impact.
