The virus is closely related to Tomato spotted wilt virus and a member of the Tospovirus group of viruses which are thrip transmitted. Seed transmission is unlikely and not reported for any host.
Moderately wide natural host range, including many ornamentals. Vegetable, agronomic and important grass and flower species listed below.

Dickeya chrysanthemi strains have been isolated from a number of different hosts in different countries. The list of all susceptible plants after inoculation by Dickeya chrysanthemi would be far longer than the natural host range, and difficult to establish. There is little if any information on seed as a pathway for this pathogen and therefore should not be regulated.
Eriwina chrysanthemi has been reclassified into Pectobacterium spp. and Dickeya spp.
Primarily ornamentals and flowers. Only hosts of Dickeye chrysanthemi or Dickeya zeae are listed below. (Ma, et.al. 2007)

Though found in many US states, the pathogen is usually restricted and localized. Probably Worldwide, though not reported. Disease outbreaks are sporadic and usually related to poor sanitation. Bulbs, floral and greenhouse crops most susceptible to disease outbreaks. No reports of seed as a pathway in vegetables and agronomic crops.
