Eggplant Mottled Dwarf Virus in Potato in Iran. D. Danesh, Department of Biology, University of Isfahan, Isfahan 81745, Iran. B. E. L. Lockhart, Department of Plant Pathology, University of Minnesota, St. Paul 55108. Plant Dis. 73:856-858. Accepted for publication 9 June 1989. Copyright 1989 The American Phytopathological Society.

A previously unrecorded disease of potatoes in west-central Iran, characterized by severe stunting, chlorosis, apical necrosis, and wilting, was found to be due to infection by a mechanically transmissible tuber-borne plant rhabdovirus. The virus had bullet-shaped particles measuring 76 190 nm in leaf-dip preparations and was biologically and serologically similar to previously described isolates of eggplant mottled dwarf virus (EMDV). This is the first report of natural occurrence of EMDV in potato.
