Suitable for crops: all crops vegetables stress (wind, rain, etc.) prevention formula: iprolon + chlorothalonil/carbendazim + thiabendazole copper + bihu + humic acid/brown sugar. Suitable for crops: all crops Vegetable phytotoxicity remediation methods (suitable for crops: all crops)① water spray washing. After spraying the wrong pesticide or causing phytotoxicity, spray the leaves with a large amount of water quickly when the early solution has not been completely penetrated or absorbed, and wash them repeatedly for 3-4 times to wash away the solution on the surface of the plant as much as possible. (2) Spraying mitigators. If the toxicity is caused by acidic chemicals, appropriate amount of quicklime can be added when spraying water; if the toxicity is caused by alkaline chemicals, appropriate amount of vinegar can be added when spraying water. If excessive spraying of copper sulfate causes phytotoxicity, it can be rescued by spraying 0.5% quicklime water; after being poisoned by stone sulfur mixture, it can be reduced by spraying rice vinegar 400-500 times solution on the basis of water washing.③ Irrigation to reduce poison. When pesticide damage is caused by excessive application of pesticides in soil, irrigation and washing of fields should be carried out as soon as possible, so that a large number of drugs can be discharged out of the fields with water. On the one hand, the water content of vegetable crops can be increased, metabolism can be promoted, the relative concentration of pesticides in the body can be reduced, and the degree of pesticide damage can be reduced. On the other hand, the concentration of pesticides in soil can be reduced to reduce the toxicity of pesticides to crops.④ Increase fertilizer application in time. If nitrogen, phosphorus, potash or decomposed organic fertilizer is applied timely, the injured plants can gradually recover their growth and improve their ability to resist phytotoxicity.
