The post Tomato Leaf Curl: Virus, Causes & Remedies For Tomato Leaves Curling appeared first on Plant Care Today.
Tomato Leaf Curl Virus also known as leaf roll affects more than just tomato plants but a whole host of plants.
Tomato leaf virus is among a number of viral diseases that infects plants and stunts their growth eventually leading to their death.
It spreads to other plants physically through the silverleaf whitefly (Bemisia tabaci). (Read our article on Whitefly Control)
This insect picks up the virus while feeding on an infected plant.
Once the whitefly is infected, it retains the virus for almost two weeks and transfers viral infections to any other plant it feeds on during that time.
The virus will leave their body after ten to twelve days and require them to get infected again in order to spread.
However, it is still long enough to infect a good number of plants.
Leaf rolling or curling can result from a variety of conditions including:
The Cooperative Extension Service At Rutgers suggests asking these questions:
A plant that has been affected by Tomato yellow leaf curl virus will appear to have a number of symptoms such as:
It can be difficult to identify this virus because the symptoms are similar to other common diseases.
Tomato leaf curl can happen at any time during the growing season but the late spring to early summer appears the most common.
The first signs of the virus will begin to show when the leaves of diseased plants start to thicken and either curl upwards or droop downwards.
The viral infection and is usually followed by the leaves changing color to reflect a faded yellow with tints of purple in the leave’s veins.
Another common symptom of this virus is flower or fruit drop as the virus spreads.
Plants with the virus will stop boring fruit altogether.
However, if the plant has borne any fruit prior to getting infected, the fruit will likely appear small, crinkled and dried out and will ripen before it’s supposed to.
Once you destroy the infected diseased plants, plant any new plants far away from the area to avoid the risk of infected whiteflies still alive.
Homeowners should:
Given that this virus is spread by silverleaf whiteflies, controlling the spread of the virus has to do mainly with controlling the spread of these insects.
Try and prevent whiteflies from attacking your plants by creating a trap for them.
A 12”x12” board painted in yellow will attract the whiteflies.
Spread petroleum jelly on this board, to catch the whiteflies before they attack your plants.
However, this may not be an effective preventive measure and will not work once plants become infected.
An alternative organic option is to spray an insecticidal soap every two to three weeks.
If a plant has been affected by the tomato leaf curl virus, take steps to ensure it can be spread to other plants.
This requires covering the infected plant in a bag to trap any potential whiteflies inside and burn the plant to keep others from feeding on it and catching the infection.
