virus
Korea, China
Extensive host range includes many weed, fruit and ornamental plant species. The vegetables and agronomic crops listed below are important
TORSXX
Nepovirus. Requires the Xiphinema americanum nematode for transmission. This pest has been reported to be in Korea.
12 Known Hosts
Cucumis melo
melon
No
TORSXX-4,TORSXX-5,TORSXX-9
Pathway not proven. Only one reference found implementing seed as a pathway, but all research was in enclosed houses and the laboratory. No evidence of seed being a pathway in nature found. A seed pathway is often inferred (TORSXX-9), but no evidence is presented.

Lactuca sativa
lettuce
No
TORSXX-6
Pathway not proven. Seed transmission from artificially inoculated plants only. No evidence of seed is a pathway in nature or from natural infections in this crop.

Impatiens spp.
impatiens
No
No references found indicating seed is a pathway.
Zinnia spp.
zinnia
No
TORSXX-11
Pathway not proven. Seed as a pathway is often speculated based on one dated reference from Japan. This reference could not be verified and it is unclear if the transmission was with naturally infected seed or in the laboratory only.

No
TORSXX-10
Pathway not proven. No evidence of seed transmission in nature. Seed pathway was shown in cross pollination experiments in the laboratory or greenhouse only and with artificially inoculated plants.

No
DVP WEB
Pathway not proven. Seed as a pathway is often speculated based on one dated reference . See reference #34 in the DVP WEB. This reference could not be verified and it appears that the research was done with one isolate in the laboratory only. No evidence of natural seed transmission.
