Viral infections are not easily cured. The viral infection led to high damage to the plants. The wild plants are infected plants growing nearby should be removed
While transplanting, sometimes the gardener might not notice that the plant is infected and has already been attacked by whiteflies. These whiteflies are the carrier of viruses that can further be transmitted to healthy plants and cause twisted tomato leaves that are upwards and also lead to the yellow coloration of leaves.
Plants seem to look droopy, and lifeless, and almost zero fruit production occurs. For this infection, the responsible virus is the Tomato Yellow leaf curl virus.
Another virus is Tomato Mosaic Virus- this viral infection also leads to the curling of leaves with other effects like dwarf leaflets, mottled-colored leaves, and browning of the inner portion of fruit.
Tobacco mosaic virus – this viral cause has almost similar effects on tomato plants as that of tomato mosaic virus. This plant pathogenic virus is easy to spread and creates a loss.
The herbicides are another factor that is causing the curling of tomato leaves. Specifically, the herbicide 2,4-D herbicide which is a hormone weed killer is washed off or carried away through the wind to tomato plants, which are sensitive to this chemical and get reacted by it. The twisted leaves are indicated by unhealthy fruits.
Wait for a few weeks if the normal growth doesn’t appear then remove it.
Removal of a plant if the damage is not reversed which can happen if little herbicide has reached the plant
Irregular and improper watering
The leaves of tomato plants might be rolling due to water not reaching the leaves which can be due to the “underwatering” of plants. Tomatoes need 4-5 cm of water in 7 days. This can vary with its size. The hot climate demands more water, tomatoes need more water during this time. In cold to humid climates, make sure that you don’t overwater the plants.
Cutting or trimming tomato plants in proportion to their size demands less nitrogen but if you keep applying fertilizer the plant will get overloaded with nitrogen, as most of the fertilizer has a nitrogen supply. Many gardeners keep using natural nitrogen supply to the plants which can cause twisting to curling of tomato leaves. To balance it out you can also plant other companion plants with tomatoes.
Winds, hot-dry weather, cold-humid conditions, drought, etc. are some of the environmental conditions that might cause the curling of tomato leaves just like the philodendron leaves curling. These environmental variations can temporarily affect the plant and can be reversed back to the form as the environment gets suitable for a tomato plant. If not the cause can be something else which can be physiological causes like root damage while preparing the soil, excess pruning, etc., or the above-mentioned causes.
