Tomato hormone poisoning how to treat?

Tomato hormonal intoxication typically presents as upward curling and stiffness in the leaves, which can significantly affect plant growth and fruit production. In greenhouse settings, weaker plants are more susceptible to this condition, with curled leaves often accompanied by a higher number of deformed or spotted flowers. The severity of the leaf curl increases with the intensity of the hormonal imbalance. Early planting combined with high temperatures creates an environment where hormonal poisoning is more likely to occur. To prevent excessive stem elongation, growers commonly apply growth regulators such as chlormequat, auxins, and dwarfing agents during the seedling stage. While these substances are intended to control plant growth, they can accumulate in the plant over time. Even if no immediate effects are visible, once the plant is exposed to stress—such as temperature fluctuations or environmental changes—the symptoms of hormonal toxicity appear rapidly. To manage early-stage hormonal poisoning, it's recommended to spray a solution of Kangfengsu at a concentration of 5 ml per 12.5 kg of water. This treatment should be repeated every four days. Alternatively, products like Life One can be used according to the manufacturer's instructions. For more advanced cases, a solution containing 5–7 ml of 2,4-D per 12.5 kg of water can be applied, with spraying intervals of 5–6 days and a total of 3–4 applications. It's important to monitor the plants closely and adjust the treatment plan based on their response. Proper timing and application techniques are crucial for effective management of hormonal intoxication in tomato crops.
