XI. Remediation methods for vegetable phytotoxicity of crop planting pest control technology
(1) water spray
After spraying the wrong pesticide or causing the phytotoxicity, the leaf can be quickly sprayed with a large amount of water when the early liquid has not been completely penetrated or absorbed, and washed repeatedly 3-4 times, and the liquid on the surface of the plant is washed away as much as possible.
(2) Spraying reliever
If it is caused by acidic agents, add appropriate amount of quicklime when spraying water; the phytotoxicity caused by alkaline agents, add appropriate amount of vinegar when spraying water.
If the phytotoxicity is caused by the excessive application of copper sulphate, 0.5% of the quicklime can be sprayed and rescued; after being smothered by the stone sulphur mixture, the medicinal damage can be alleviated by spraying 400-500 times of the vinegar on the basis of washing.
(3) Irrigation and detoxification
When the soil is applied excessively, the phytotoxicity should be irrigated and washed early, so that a large amount of drugs can be discharged from the field with water. On the one hand, increase the cell water content of vegetable crops, promote metabolism, reduce the relative concentration of pesticides in the body, and reduce the degree of phytotoxicity; Reduce the concentration of pesticides in the soil and reduce the toxicity of pesticides to crops.
(4) Add fertilizer in time
After crop damage occurs, growth is hindered and the growth is weakened. If nitrogen, phosphorus, potassium fertilizer or decomposed organic fertilizer is applied in time, the affected plants can be gradually restored to growth and improve their ability to resist phytotoxicity.
Suitable for crops: all crops
