Cucumis sativus
cucumber
No
PSDMAC-6
Pathway not proven. Seed as a pathway has not been proven in this crop. Seed often inferred as a pathway due to this pathogen being seed borne in other cucurbits.
Yes
Seedling Grow out, PCR tests, Immunomagnetic separation-PCR wash
Though seed as a pathway is not proven in cucumber, testing is offered by commercial laboratories.
