In the process of prevention and control of pests and diseases of vegetables in protected areas, the effects of special climate conditions in protected areas can easily cause damage to vegetables. If remedial measures are taken promptly, the degree of damage to the plants can be reduced and economic losses can be reduced. Here are a few remedies: 1. Spraying with water If plants spray liquids causing phytotoxicity, they can be quickly sprayed with fresh water, 3-4 times, in conjunction with cultivator pines, when the early liquids have not yet fully penetrated or been absorbed. Soil, promote root development. 2. When applying pesticides for quick-impact fertilizer plants, it is necessary to timely apply top-dressing fertilizers, promote growth and development, and increase their ability to resist phytotoxicity. 3. Use antidotes or plant growth regulators According to the chemical nature of pesticides that cause phytotoxicity, neutralize the drugs with their opposite values. For example, 0.5% quicklime water may be used for copper sulphate poisoning; gibberellin may be sprayed by paclobutrazol phytotoxicity, but Be sure to use the concentration. 4. Watering and washing the fields For the land with excessive application of the soil, the fields should be washed and drained as soon as possible, and a large amount of drugs should be discharged outside the field. 5. Remove the victim's organs in time After the symptoms appear, remove the affected branches, leaves, and fruits in time to prevent the agent from continuing to conduct and infiltrate.
