During the 3 days after the application of the pesticides, the crop growth conditions, especially the application of herbicides, plant growth regulators, and phoxim, different rice fields, should be frequently checked. If phytotoxicity is found, emergency measures should be taken as soon as possible to remedy the damage caused by phytotoxicity.

First, the spraying of pesticides, such as pesticides caused by acidic pesticides can be used to spread some lime or ash. Strong phytotoxicity can also be sprayed with 1% bleach solution. Alkaline pesticides such as ammonium sulfate can be added to the phytotoxicity caused by alkaline pesticides. No matter what kind of pesticide is sprayed, spraying 0.1%-0.3% potassium dihydrogen phosphate solution or using 0.3% urea solution plus 0.2% potassium dihydrogen phosphate solution can significantly reduce the damage caused by phytotoxicity.

Second, spray water wash, such as foliage and plants caused by spraying caused by the discovery of harm can be promptly sprayed with plenty of water on the affected leaf surface sprayed repeatedly 2-3 times and cultivating loose soil to promote root development to enhance crop recovery.

III. Drainage and Irrigation Water Remediation The proper irrigation and drainage of some pesticides caused by herbicides can reduce the degree of injury. For example, if the phytotoxicity caused by pomebarthrin is used to replace the field water immediately after the initial stage, intermittent drainage and other measures can be used to ease or reduce the phytotoxicity.

Fourth, fertilization remedies For foliar drug spots, leaf margin charred or plant damage and other symptoms of injury can be sprayed Cui Miao, Yunda 120 and other plant growth regulators can also increase fertilizing materials to promote plant growth and recovery.

5. Spraying hormone remedies Herbicides that inhibit or interfere with plant growth can be sprayed with glycans and other hormone-like plant growth regulators to reduce the extent of injury. After the crop has produced phytotoxicity, comprehensive remedial measures should be taken based on the type of pesticide and the degree of damage to the crop in order to reduce the hazard more effectively.

Six, scientific medicine crops are often irreversible remedies and are more passive. It is extremely important to prioritize the selection of pesticide species and strictly control the use of methods and concentrations. This is the fundamental reason for preventing the occurrence of phytotoxicity.
