In the process of agricultural production management, the use of pesticides to control crop pests and diseases is one of the main means; the long-term use of pesticides will inevitably lead to the phenomenon of spraying pesticides; the light pesticides affect the normal growth of crops, spots, withered, rolled leaves, Deciduous fruit falling, etc., can cause serious crop deaths. 1. Remove the damaged branches and leaves in time: Once the wrong pesticides are found, remedial measures should be taken in time. The commonly used remedies for spraying pesticides are as follows: After the leaves are damaged, the leaves that have turned green and discolored should be removed in time to suppress the pharmaceutical agent. Penetration conduction within the plant. Second, spray water. After spraying the medicine by mistake or causing phytotoxicity, spray the water quickly and wash the surface liquid of the affected plant. The phytotoxicity caused by alkaline agents can be added with proper amount of vinegar when spraying water; the phytotoxicity caused by acidic agents can be added with 0.1% quicklime when spraying water, so that the agent can be neutralized and it can be invalidated as soon as possible. At the same time, it is necessary to pay attention to the ventilation of the greenhouse, and to reduce the temperature and temperature to facilitate the discharge of harmful gases. Third, timely watering the shed vegetable watering. It can increase the cell water in the plant, promote metabolism and reduce the relative content of harmful substances. At the same time, watering can also dilute the harmful substances accumulated in the roots of the plants. Fourth, spray the mitigator. For example, 0.5% of quicklime water can alleviate the phytotoxicity caused by copper preparations; 0.2% of soapy liquid can alleviate the phytotoxicity caused by organophosphorus pesticides. Fifth, balanced fertilization. Appropriately apply quick-acting compound fertilizer or foliar spray full-nutrient leaf fertilizer to promote rejuvenation of seedlings and improve resistance to phytotoxicity.
