Last Updated: 2024/11/06, First, elution. Most chemicals are not resistant to water scouring. If you find that the medicine is not used properly, you can immediately wash the stems and leaves repeatedly with a sprayer filled with water, so as to flush away the chemicals left on the surface of the cotton plant and reduce the drug damage; when flushing, the air pressure of the sprayer should be sufficient and the amount of water sprayed should be large. For the cotton fields with soil application and the drug damage caused by some herbicides, the soil can be irrigated immediately and the residual chemicals can be leached into the deep soil. Second, fattening. In general, fertilizer or foliar spraying should be applied to the symptoms such as leaf spot, leaf margin scorching, plant yellowing and so on.

First, elution. Most chemicals are not resistant to water scouring. If you find that the medicine is not used properly, you can immediately wash the stems and leaves repeatedly with a sprayer filled with water, so as to flush away the chemicals left on the surface of the cotton plant and reduce the drug damage; when flushing, the air pressure of the sprayer should be sufficient and the amount of water sprayed should be large. For the cotton fields with soil application and the drug damage caused by some herbicides, the soil can be irrigated immediately and the residual chemicals can be leached into the deep soil.

Second, fattening. In general, the degree of drug damage can be reduced by increasing fertilizer or foliar spraying of Lufeng 95, Gaomeishi, plant power 2003, Tianda 2116, etc., for the symptoms of leaf spots, leaf edge scorching, plant yellowing and so on. For example, when cotton seedlings are damaged by 2mai 4murD butyl ester, an appropriate amount of available nitrogen fertilizer can be applied to promote the growth and development of cotton plants and restore their normal growth and development as soon as possible.

Third, chemical control. The drug damage caused by some herbicides and plant growth regulators can be reversed by spraying plant growth regulators after the drug damage. For example, spraying 30~50ppm gibberellin solution on cotton seedlings can obviously promote the growth of cotton seedlings after being damaged by 2Jing 4murD, while spraying "920" solution or Jieshangling can alleviate the drug damage when cotton is damaged by dwarfin.
