N2  - The barley yellow-dwarf virus was found to be widely distributed in California in that the disease has been observed or the virus recovered from all but a few counties. The virus was recovered in 1954-55 from specimens collected in 15 widely scattered counties. An attempt was made to determine if the virus was present in other States of the United States. Oat, barley, wheat, and bromegrass specimens suspected of carrying the virus was shown to be present in the specimens from 8 States, as follows: Arizona, Arkansas, Illinois, Maryland, Minnesota, Oregon, Washington, and Wisconsin. The results are presented as good evidence of a wide distribition of the virus in the United States, and a reference is made to a report by Oswald and Thung of the occurrence of the virus in Holland
