Plant Dis. 65:753-754. Accepted for publication 20 June 1981. Copyright 1981 American Phytopathological Society. DOI: 10.1094/PD-65-753.

Identity of the oca strain of arracacha virus B, isolated from naturally infected potato in central Peru, was confirmed by symptomatology in indicator hosts, properties in sap, particle morphology, and serologic reactions. The virus was transmitted through potato tubers to progeny plants, but infection was symptomless.
