The crop growth should be checked frequently within 3 days after the application of the pesticide, especially the application of herbicides, plant growth regulators, and phoxim and isoniazid. If phytotoxicity is found, emergency measures should be taken as soon as possible to reduce the damage caused by the phytotoxicity.
If the spray is neutralized and the phytotoxicity is caused by acidic pesticides, some quicklime or ash may be applied. If the phytotoxicity is strong, it can also be sprayed with 1% bleaching powder. For the phytotoxicity caused by alkaline pesticides, acid fertilizers such as ammonium sulfate may be added. No matter what kind of phytotoxicity, foliar application of 0.1%~0.3% potassium dihydrogen phosphate solution, or 0.3% urea solution plus 0.2% potassium dihydrogen phosphate solution can significantly reduce the damage caused by phytotoxicity.
Spraying water and leaching, such as foliar surface and plant spraying, cause phytotoxicity. When found in time, it can be quickly sprayed with a large amount of clean water to spray the affected leaves, and sprayed repeatedly for 2~3 times.
Strengthening field management should strengthen the management of the phytotoxicity of the field, combined with watering, increase the application of manure and manure, ammonium bicarbonate, ammonium nitrate, urea and other quick-acting fertilizers, promote root development and regeneration, restore the physiological functions of the affected plants, and promote crops. Healthy growth to reduce the harm of herbicides and other phytotoxics to crops.
The cultivating loose soil strengthens the cultivating loose soil, breaks the soil compaction, enhances the soil permeability, enhances the ground temperature, promotes the beneficial microbial activities, accelerates the decomposition of soil nutrients, enhances the roots' ability to absorb nutrients and water, and restores the growth and development of the plants as soon as possible. The damage caused by the phytotoxicity.
Drainage irrigation is a phytotoxicity caused by some herbicides. Appropriate drainage can reduce the degree of phytotoxicity. For example, if the phytotoxicity caused by chlorpyrifos is used, the field water should be replaced immediately in the initial stage, and intermittent irrigation and drainage measures can be used to alleviate or mitigate the phytotoxicity.
Fertilization can remedy the phytotoxicity of foliar plaques, leaf stalks or plant yellowing. It can spray plant growth regulators such as Cui Miao and Yunda 120, and can also increase fertilizer application to promote plant growth.
Spraying Hormone Remediation For herbicides that inhibit or interfere with plant growth, after the occurrence of phytotoxicity, hormonal plant growth regulators such as gibberellin can be sprayed to alleviate the degree of phytotoxicity. After the crop has caused phytotoxicity, comprehensive remedial measures should be taken according to the type of pesticide and the degree of crop damage, in order to reduce the harm more effectively.
The phytotoxicity of scientifically used crops is often irreversible and the remedies are relatively passive. It is extremely important to select the pesticide variety in advance, and strictly control the method of use and concentration. This is the root of preventing the occurrence of phytotoxicity.
Timely destruction and replanting should be a serious phytotoxicity. On the basis of identifying the cause of phytotoxicity, we should immediately take targeted remedial measures. If there is serious phytotoxicity and no remedy, we must hurry to replant, replant and compensate for the loss.
