Method for rescuing crop phytotoxicity

Crops often experience phytotoxicity, which is a common issue when they are exposed to pesticides. This can occur due to improper application, low-quality products, or incorrect concentrations of the chemicals. Phytotoxicity can hinder plant growth and reduce crop yields, making it essential to take immediate action once symptoms appear. To address this problem, China has developed several effective methods for crop injury rescue. These strategies aim to minimize damage and help crops recover as quickly as possible. 1. **Irrigation and Disinfection** For cases where herbicides or toxic substances in the soil have caused harm, draining water or using sequential irrigation can help reduce the impact. If plants show signs of stunting due to herbicides, immediate watering and disinfection should be performed. Follow-up with interstitial irrigation and quick-release fertilizers can further alleviate the damage. 2. **Spray Water to Remove Pesticides** If pesticide-induced phytotoxicity is detected early and the damage is mild, spraying the affected plants with water or 0.5% lime water can help wash away the residue. Repeating this process 3–4 times ensures that the chemical is removed effectively. Combining this with soil fertilization can speed up recovery and restore normal growth. 3. **Remove Affected Parts** When systemic insecticides are used on fruit trees through injection or other methods, high concentrations can cause severe damage. In such cases, removing the affected branches promptly is crucial. This prevents the pesticide from spreading further into the plant and helps stop the damage from worsening. 4. **Ploughing and Replanting** In severe cases where most of the crops are dead, the field should be exposed to sunlight first, then thoroughly washed. After plowing and turning the soil, any remaining pesticide residues will be neutralized, allowing for replanting. For localized damage, rinse the area with water, till the soil, and replant. Applying quick-acting fertilizer after planting can help new crops catch up and grow evenly. Staying informed about pesticide use and safety is vital for farmers. Following updates from China's pesticide network can provide valuable insights and help prevent future incidents of phytotoxicity. Always prioritize safe and responsible pesticide practices to protect both your crops and the environment.
