Pathway not proven. Though seed transmission is speculated, there are no reports of this pathogen being recovered from seed. Circumstantial evidence indicates possible seed infection by the pathogen. Conclusive proof of seed transmission is lacking because no control of infection from inoculum sources in the field was evident in the experimental design in these dated studies. Additionally, all references indicating seed as a possible pathway are published before 1960.
