Members of the genus,
Lilium, are susceptible to several
different viruses. The most common ones are the Lily Symtomless Virus (LSV), Tulip Breaking Virus (TBV) and
Cucumber Mosaic Virus (CMV). These virus are moved from
plant to plant in the saliva of
aphids feeding on the
lilies.

 |
Typical of most viral diseases of plants, these
types are generally not fatal to the lily. They
cause streaking or mottling in the leaves, distorted
and twisted growth in the stem or leaves, loss of
vigor and plant size and may cause rings on the
bulbs.

-
Resistance - There is a
range of susceptibility among the various species
and cultivars of lilies. Use those that are
resistant IF you have had a problem with virus
diagnosed in your garden.
-
Insect Control - Try to
minimize the number of
aphids feeding on your
lilies.

- Sanitation - Remove
plants that have been diagnosed with virus. They will
never get better. Destroy them away from the garden and
do not use them in a compost pile.
- Disinfect - IF you have
a virus problem, be sure to disinfect tools used to
prune or cut lilies or their bulbs. You can use a 1 part
bleach to 9 parts water solution.
- Chemical Control -
There are currently no chemical controls for plants
including lilies that are infected with a virus.
- Propagation - During
the early part of the 20th century, a serious virus
infection threatened the entire Easter lily crop.
Eventually, they figured out that the virus moved up the
plant at a slower rate than the tip of the stem grew.
So, they were able to take cuttings from the uninfected
tips to produce new, virus-free plants.
