virus
China, Nepal
Main: cucumber
CLSV00
Cucumber leaf spot virus is transmitted in the field by the soil-inhabiting fungus Olpidium bornovanus, which carries virus particles to plant roots. Mechanical transmission is also possible under experimental conditions. Reports of seed transmission are unsubstantiated, and the main natural pathway of spread is through the fungal vector.
4 Known Hosts
Citrullus lanatus
watermelon
Not a host
CLSV00-2, CABI CPC, DPV WEB
Watermelon has only been shown to be a host in laboratory studies and only produces local lesions. No references found indicating that watermelon is a natural host for this virus.

Cucumis melo
melon
No
CLSV00-3, CLSV00-5, CLSV00-7, CABI CPC, DPV WEB
Melon seed is not a pathway for Cucumber leaf spot virus. A report indicates that inoculation of melon results only in local lesions, consistent with a non-host reaction. However, one report described infection in the field, but this has not been confirmed.

Cucumis sativus
cucumber
uncertain
CLSV00-2, CLSV00-3, CLSV00-4, CLSV00-5, CLSV00-7, CABI CPC, DPV WEB, CLSV00-8, CLSV00-9, CLSV00-10, CLSV00-11
Seed transmission of Cucumber leaf spot virus in cucumber is uncertain. The virus is mainly spread in the field by the soil fungus Olpidium bornovanus, and the overall incidence is limited. A single report by Weber cites unpublished experimental data suggesting possible seed transmission, but because these results cannot be evaluated and no other evidence supports seed as a pathway, transmission through seed in cucumber remains unverified.

Cucurbita spp. seed is not a pathway for Cucumber leaf spot virus. A report indicates that inoculation of Cucurbita spp seed results only in local lesions, consistent with a non-host reaction. However, only one report described infection in the field, but this has not been confirmed.
