How to remedy the herbicide damage?

How to remedy the herbicide damage? Is there a simple and practical way to remedy it? Please also know the netizens to help introduce the method in the process of agricultural planting, herbicide damage caused by operation errors occur from time to time. The farming network has sorted out four remedial methods after herbicide damage, which are listed below for netizens' reference. First, rinse the plant with clean water in time: when the crop sprays too much herbicide or the sensitive leaves of the nearby crop are damaged by the herbicide, you can use a clean sprayer to fill the water and spray it several times in a row to remove or reduce the residue of herbicide on the crop. For some herbicides that are prone to dispersion and failure of alkaline substances, 0.2% quicklime 0.2% sodium carbonate water dilution can be used to wash crops, which has a very good effect on eliminating drug damage. For the fields with continuous drug damage, in addition to foliar spray cleaning, sufficient irrigation should be carried out to promote the root system to absorb a large amount of water, reduce the drug concentration in the crop and play a good mitigation role. For the field with excessive application of pesticide in the soil, the method of irrigation, drainage and washing should be adopted to remove a large number of drugs from the field, which can effectively reduce the drug damage. Remedial method 2. Topdressing quick-acting fertilizer to crops: we can refer to the general amount of topdressing in crop growing season, combined with watering and topdressing quick-acting chemical fertilizer, in addition to topdressing soil with ammonium nitrate and ammonium sulfate, and foliar spraying 1% urea or 0.3% potassium dihydrogen sulfate solution can promote crop growth, improve drug resistance and reduce drug damage. Remedial method 3. Ploughing and loosening the soil in the middle of the crop: the times of loosening the soil in the middle ploughing can be increased appropriately according to the growing season of the crop. Mid-tillage should be from shallow to deep, break soil consolidation, enhance soil permeability, increase soil temperature, promote beneficial microbial activities, speed up the decomposition of soil nutrients, enhance the absorption capacity of roots for nutrients and water, and restore plant growth and development as soon as possible. After comparing the cotton field unearthed with Acetochlor, the soil temperature of 4 times of continuous intertillage was 1.8cm higher than that of 0-10cm at seedling stage, which was 1.8cm higher than that of 0-10cm at seedling stage. ℃, the plant height was 3.3cm higher than that of 0-10cm. Remedial method 4. Spraying plant growth regulators: in time after the occurrence of drug damage, the plant growth regulators of brassine type are used for crops, and the diluent is sprayed evenly on both sides of crop leaves with sprayers, so that the leaves are covered with water droplets. After spraying, it can get the effect of rising from the dead, so that the growth of crops can be restored rapidly. according to the nature of drug damage, the opposite drugs can be used to neutralize and alleviate. If the wheat was sprayed too much 2mae4murD butyl ester, gibberellin of 20ppm could be sprayed, and the growth of stems and leaves returned to normal 7 days after spraying, which was more than 10% higher than that without gibberellin spraying.
