"Five Laws" Remedy for the Phytotoxicity of Protected Vegetables

In the process of prevention and control of vegetable pests and diseases in protected areas, it is easy to cause vegetable phytotoxicity due to the special climatic conditions of protected areas. If remedial measures are taken in a timely manner, it can reduce the degree of plant damage and reduce economic losses. Several remedies are now introduced:

Water spray

If the plant sprays the liquid to cause phytotoxicity, the leaf can be sprayed with clean water 34 times repeatedly, and the cultivating loose soil can be used to promote root development when the early liquid has not been completely penetrated or absorbed.

2. Pursuit of quick-acting fertilizer

When the plant produces phytotoxicity, it is necessary to timely water and apply quick-acting fertilizer to promote growth and development and improve its ability to resist phytotoxicity.

3. Use antidote or plant growth regulator

According to the chemical nature of the pesticide causing the phytotoxicity, the drug is neutralized with the opposite sex value. For example, 0.5% quicklime water can be used for the copper sulfate poisoning; the paclobutrazol can be sprayed with paclobutrazol, but the concentration should be paid attention to.

4. Watering and washing the fields

For plots with excessive application of soil, the fields should be washed and drained early, and a large amount of drugs should be discharged from the field with water.

5. Remove the affected organs in time

After the symptoms of the victim appear, the affected branches, leaves and fruits should be removed in time to prevent the drug from continuing to conduct and penetrate.
