Spraying clean water After spraying the wrong medicine or causing phytotoxicity, spray the clean water quickly and wash the surface of the damaged 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.
Removal of damaged branches and leaves After the leaves are subjected to phytotoxicity, the leaves that have turned green and discolored should be removed in time to suppress the penetration of the pharmaceutical agent into the plants.
Watering in time shed vegetable watering 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.
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.
Spraying mitigating agents such as 0.5% quicklime water can alleviate the phytotoxicity caused by copper preparations; 0.2% soap liquid can alleviate the phytotoxicity caused by organophosphorus pesticides.
