How to Treat Mosaic Virus
There is no known cure, but all is not
necessarily lost. Some advice is to dig up the plant and burn it
but that advice is now generally thought to be out of date.
Mosaic virus is transmitted from plant to plant in two key ways,
by insects and by you, the gardener. Both result in the same
symptoms of yellow leaves.
The virus won't kill your plant, it will reduce
its vigour and ability to produce crops. So, if you want to
keep your plant then follow the steps below.
1. After handling a plant with mosaic virus
always wash your hands thoroughly before touching another plant.
This will stop the disease being transmitted to your other
2. Try and leave tending to plants with any sign
of the disease to the last, especially when removing yellow leaves as
3. Remove all yellowing or bronzed leaves and
put them away for burning.
4. Make sure that infected plants are well
watered and well fed but not overfed.
If you take the steps above, the plants will
recover a lot of their vigour, the yellow leaves will slowly
reduce and the danger of cross-infection will be minimal. Clear
up all debris during the season and especially at the end of the
season, no signs of infected leaves should be left on the soil.
Next season, definitely don't plant tomatoes or
cucumbers in the same area again. If you are using a greenhouse,
remove all the top soil and replace it with new soil. Increasing
the temperature in the greenhouse above 24°C (75°F) has been
proven to reduce the effects of mosaic virus.
