How to prevent the damage caused by Plant growth regulators in Cotton

How to prevent the damage of plant growth regulators in cotton? Please guide the drug damage and symptoms of plant growth regulators: if the concentration and dosage of the commonly used dwarftin is too high, it will inhibit the growth of cotton plant, make the cotton plant too short, the boll will fall off easily, and even the cotton boll will become deformed. Excessive spraying of thalidomide will inhibit its growth, resulting in thick green leaves, thickening leaves, deformities, shrinkage, short internodes of the main stem and so on. Prevention and control measures: 1. Strict operation. When in use, drugs should be selected in strict accordance with the operating rules, and read the concentration, method and time on the instructions repeatedly to prevent drug damage caused by improper use. two。 Clean it in time. After the occurrence of drug damage, the leaf surface can be washed with a large amount of clean water, and irrigation and drainage washing medicine can be used in the soil. 3. Neutralize and detoxify with a safety agent, and you can spray 0.5%-1% lime milk to neutralize and detoxify. Because "920" has the function of promoting the growth, division and differentiation of plant cells, when cotton is damaged by dwarf and metoprolol, it can be sprayed with a certain concentration of "920" to relieve the damage. Paraquat is passivated and ineffective when it comes into contact with soil, and the method of throwing mud water is taken immediately after accidental spraying, which can make the drugs on the surface of crops invalid. 4. Cotton field spraying equipment should be special, do not use sprayers and measuring cups that have been sprayed with 2meme 4murD butyl ester and dimethyl tetrachloride, etc., and must be cleaned thoroughly before spraying other pesticides. 5. Strengthen protection, use sterilized herbicides to spray between cotton lines, choose windless weather, install a protective cover on the sprinkler, lower the sprinkler when spraying, and try not to spray the liquid on the cotton.
