Five ways to solve phytotoxicity

Some farmers apply pesticides to manage pests and diseases, but improper use of these chemicals often leads to phytotoxicity in crops. This can result in symptoms such as leaf burn, flower and fruit drop, stunted growth, and even plant death. However, prompt remediation measures can significantly reduce the damage caused by pesticide overuse or misuse. One effective method is to rinse the plants with large amounts of water. If a particular pesticide has caused phytotoxicity, spraying the crop with clean water 2–3 times can help wash away the chemical from the leaves and stems. Adding 0.2% sodium hydroxide or 0.5% lime water to the rinsing solution can further enhance the breakdown of the pesticide, as many chemicals are sensitive to alkaline conditions. At the same time, watering the plants increases cellular moisture, dilutes the concentration of the chemical inside the plant, and helps reduce the overall phytotoxic effect. Another approach is to apply antidote solutions that counteract the harmful effects of the pesticide. For example, if omethoate or parathion causes damage, spraying a 0.2% borax solution can help alleviate the injury. In cases where paclobutrazol causes growth inhibition in rapeseed or peanut seedlings, applying a 90% solution of a growth regulator can restore normal development. For phytotoxicity caused by copper sulfate or Bordeaux mixture, spraying 0.5% lime water can effectively reduce the damage. In some cases, irrigation and drainage can help lower pesticide residues in the soil. For instance, after initial signs of phytotoxicity from herbicides like Trichosanthes, immediate drainage followed by controlled irrigation can reduce residual chemicals, thereby minimizing further harm to the crop. Applying nitrogen fertilizers promptly can also help mitigate foliar damage, yellowing, or scorching. Applying 5–12 kg of urea per 667 square meters (1 mu) depending on soil fertility and crop condition may be beneficial. Additionally, using phosphorus and potassium fertilizers can support plant nutrition, improve root development, and strengthen the plant’s resistance to chemical stress, especially in young seedlings. Finally, when parts of a fruit tree are affected due to over-application or high concentration of chemicals, damaged branches should be removed immediately to prevent the spread of the toxin. Irrigation should also be performed to stop further damage from spreading and to promote recovery. These combined efforts can greatly improve the health and survival of the affected crops.
