A new virus disease of tomato, with symptoms characterized by mosaic, epinasty, and terminal necrosis of branches and leaflets, was found to be caused by coinfection of plants by tobacco mosaic and potato Y viruses. Identification of the viruses was based on host range, serology, electron microscopy, physical properties, and aphid transmission.
