Tobacco rattle virus (TRV) produces characteristic ring spot symptoms on foliage of peony. Previous reports of Peony mosaic virus or Peony ring spot virus as causal agents of this disease are very likely to be TRV. TRV is widely prevalent in many parts of the world with a wide host range (over 100 plant species). Important hosts of TRV include vegetables such as beet, pepper, and potato and ornamentals such as iris, gladiolus, peony, and tulip. TRV is transmitted by nematodes in the genera Trichodorus and Parathricodorus.
