For the purpose of this article, we will be looking into more details on tomato plant disease curled leaves.

Tomato Plant Diseases Curled Leaves And Possible Remedies

One culprit to your tomato leaves curling is a virus. There are 3 main viruses that can cause your tomato plant to curl. They include:

1.    Curly Top Virus: Tomato Plant Diseases Curled Leaves

Symptoms: Once you notice the top portion of the plant curling upward or the whole leaves pointing upwards, it may be a sign of the curly top virus.

Curly top virus in tomato plant is caused by leaf-hoppers pests chewing your tomato plant. The pest mostly chooses one plant to chew. The good thing is that the virus won’t spread to other plants even if the infected and uninfected tomato plants are touching each other.

But when these leaf-hoppers bugs chew on an infected plant and fly to chew on another uninfected plant, chances are the leaf-hopper bugs will give the uninfected plant that virus.

You can still allow the plant to attain maturity and harvest your crop. This is if the plant is already growing fruit, the plant can still produce ripened fruit. However, if they were infected in their early stage, their growth may be stunted and ripen prematurely.

But the best thing to do is to get rid of the plant to avoid leaf-hoppers spreading the virus to uninfected plants when they chew on them.

2.    Tomato Yellow Leaf Curl

Symptoms: Leaves can curl upward or downward and the leaf can roll in a cup-like fashion. More symptoms are marginal yellowing of leaves, leaf size reduction, dropping of flowers or fruit, and stunted plant growth.

Tomato yellow leaf curl is spread by whiteflies. The best thing to do is to keep the population of whiteflies in your garden under control. You can do this by spraying neem oil once or twice every week so whiteflies won’t come close to your plant. But once the disease infected the plant and manifested, it’s hard to get rid of it.

However, you can also do this to help your plant: get a big trash bag and wrap it by covering the whole tomato plant. Then tie the open end of the bag around the tomato trunk at soil level.

Cut the plant off at the soil level and allow it to sit in the hot sun for a day or two. This will kill all the whiteflies that contain most of the virus. Then begin a neem spraying scheme after this.

3.    Tomato Mosaic Virus

Symptoms: Leaves rolling upwards and coloring of leaves such as internal browning. The plant may also have stunted growth.

Tomato Mosaic Virus

The best thing is to remove infected plants and get rid of them. This mosaic virus can live in the soil for up to 2 years. Therefore, when you’re watering your tomato plant, water the base and never allow water to splash over the leaves.

When you do this, it will reduce the chances of the mosaic virus getting into your plant leaves. This is just in case the mosaic virus still lives in the soil.

The best way to overcome the tomato mosaic virus is to grow resistant varieties.

Other Reasons For Tomatoes Leaves Curling

Apart from disease-related issues, tomato plant leaves can be all curled up for other reasons. We have physiological reasons which are often resolvable. Then we have the herbicide drift.

  • Physiological Reasons: Physiological reasons are caused by environmental stress. This environmental stress can include heat, under watering, overwatering, dry weather, excess nitrogen application, etc. Usually, the leaves won’t change their green color but they will curl upward and most of these causes are remediable.
  • Herbicide Drift: This is when you spray herbicide in your garden or you live close to where one has been sprayed, some of the residues can drift over your tomato plants. This can cause your tomato leaves to curl. Your plant may recover from this. But if they don’t it’s best you pull out the whole plant and dispose of it.
