Method for rescuing crop phytotoxicity

Crop phytotoxicity is a common issue in agriculture. It often occurs when pesticides are misused, of poor quality, or applied at incorrect concentrations during pest and disease testing. This can lead to damage in crops, affecting their growth and reducing yield. Therefore, it's crucial to take immediate action to rescue the affected plants. In China, pesticide experts have developed several effective methods for remedying crop injury. Here are some key strategies: 1. **Irrigation and Disinfection** For cases caused by herbicides or toxic substances in the soil, draining or flooding the field can help reduce the severity of phytotoxicity. If dwarfism is observed due to herbicide exposure, immediate watering and disinfection should be carried out. Subsequent irrigation and the application of quick-release fertilizers can significantly reduce the impact. 2. **Spray Water to Wash Pesticides** When phytotoxicity is detected early and the damage is minor, washing the affected leaves with water or 0.5% lime water can help remove residual chemicals. Repeating this process 3–4 times can effectively wash away the remaining pesticide. Combining this with soil fertilization can accelerate recovery and restore plant growth. 3. **Remove Affected Parts** In cases where systemic insecticides cause damage, especially in fruit trees, it’s important to promptly prune the affected branches. Removing the damaged parts prevents the pesticide from spreading further through the plant. After pruning, watering the area helps stop the damage from worsening. 4. **Ploughing and Replanting** In severe cases where most plants are dead, the field should be exposed to sunlight, washed thoroughly, and then plowed to eliminate residual pesticides. Then, the crop can be replanted. For localized damage, rinse the area, till the soil, and replant. Applying quick-acting fertilizer after planting helps the new crop catch up and achieve balanced growth. It's essential to stay informed about pesticide usage and follow guidelines from trusted sources.
