Lettuce big-vein disease causes leaf distortion and ruffling in affected lettuce plants.
This disease was first associated in 1983 with a rod-shaped virus named lettuce big-vein associated virus (LBVaV), which is transmitted by the obligately parasitic soil-inhabiting fungus, Olpidium brassicae.[1] However, in 2000, a second virus, Mirafiori lettuce big-vein virus (MLBVV), was found in lettuce showing big-vein symptoms. Furthermore, since the lettuce infected with LBVaV alone doesn't develop the symptoms while the infected with NLBVV one does, the latter virus is considered to be a main agent of the big-vein disease.[2]

Symptoms
Affected plants have veins that become large and clear, causing the rest of the leaf to become ruffled. Severely infected plants may fail to form a lettuce head.[1]
Control
- Grow disease-resistant cultivars.
- Use disease-free healthy seeds.
- Treat with methyl bromide, chloropicrin, or dazomet solution.
