PHSPAV-2,PHSPAV-4
Pathway not proven. The pathogen has been found on seed in laboratory seed tests and some references indicate possible seed transmission, but it is not considered important in spread in nature. Seed is probably not important in epidemiology of the disease.
Seed treatments
Primarily used to protect emerging seedlings from inoculum in debris.
