Lettuce mosaic virus causes mottling, stunting, and poor head formation in lettuce, making it one of the most damaging diseases affecting lettuce worldwide. It is primarily transmitted by aphids in a non-persistent manner, mechanically through sap and through infected seed in lettuce.
6 Known Hosts
Cichorium spp.
endive, cichory
No
LMV000-3, CABI CPC, DPV WEB
No references found indicating Chicorium spp. seed is a pathway.

Indexed and certified seed. Seed production companies utilize a combination of field mitigation and seed testing to control this virus
A heat treatment for seed exists but is impractical for large-scale seed treatment. However, it is adviseable to use this on small amounts of seed such as those used by seed companies for increase and breeding purposes.
LMV000-14, LMV000-6
