What does LMV mean?

LMV is the short form for Lettuce Mosaic Virus. It is one of the most common viruses that infect huge amounts of lettuce crops worldwide. It is a virus that is seed-borne in all major types of lettuce. All major types of lettuce such as crisphead, Boston, leaf, cos, Bibb, etc. get infected by LMV.

The virus is caused due to infected seeds, whereby the weed hosts are the carriers of the virus. The virus is then spread to nearby flora and throughout the crop by vectors called aphids. The virus can lead to large-scale destruction in the produce of lettuce.

Effects of LMV

Just like every other plant virus, the Lettuce Mosaic virus is not harmful to humans but causes damage to the lettuce plant. It leads to defects in the color of leaves and distortions. This leaves the produce not fit for purchase by customers. Other similar crops such as spinach and peas can also be affected by the virus.

Symptoms for the virus

Symptoms of LMV depend on a variety of factors such as the variety of lettuce, age of the plant and the environment. Some of the symptoms of the virus are:

• Infected leaves of plants develop green and yellow mosaic patterns on them, thus giving them their characteristic name.
• Vein clearing
• Some varieties develop distortions and stunting in their leaves.
• Some leaves roll downwards towards their tips.
• Some plants grow leaves with irregular shapes and fail to form small heads.
• Plants infected at later stages of growth develop mottling on leaves.
• Flowering plants undergo chlorosis of the leaves

Treatment and Prevention

The one main thing regarding plant viruses such as LMV is that once infected the seeds cannot be treated, it can only be prevented.

The virus can be prevented in two major ways.

• Seeds can be tested before planting and only the healthy ones should be planted.
• Incorporate resistance to the virus in the seed itself.
