What are the remedial measures for pesticide damage in cotton

Growing Techniques 0 views
1. Washing. Most chemical agents are not resistant to water washing. If improper application is found, a sprayer can be immediately filled with clean water and sprayed repeatedly over the stems and leaves to wash away the pesticide remaining on the surface of the cotton plants and reduce the damage; when washing, the sprayer pressure should be sufficient and the amount of water sprayed should be large. For cotton fields where soil application was used and for damage caused by some herbicides, irrigation can be applied immediately to wash the soil, leaching the residual pesticide into the deeper soil layers. 2. Fertilizer supplementation. Generally, for damage with symptoms such as leaf spots, scorched leaf margins, and plant yellowing, applying additional fertilizer or foliar spraying

For cotton fields where soil application was used and for damage caused by some herbicides, irrigation can be applied immediately to wash the soil, leaching the residual pesticide into the deeper soil layers.

2. Fertilizer supplementation. Generally, for damage with symptoms such as leaf spots, scorched leaf margins, and plant yellowing, applying additional fertilizer or foliar spraying of Lufeng 95, Gaomeishi, Plant Power 2003, Tianda 2116, etc. can all reduce the severity of the damage. If cotton seedlings show damage from 2,4-D butyl ester, an appropriate amount of quick-acting nitrogen fertilizer can be applied as a top dressing to promote branching and leaf growth, so that the cotton plants can resume normal growth and development as soon as possible.

3. Chemical regulation. For damage caused by some herbicides and plant growth regulators, plant growth regulators can be sprayed in a targeted manner after the damage to carry out reverse regulation. For example, after cotton seedlings suffer damage from 2,4-D, foliar spraying with a 30-50 ppm gibberellin solution has a clear effect in promoting plant growth; when cotton suffers damage from chlormequat chloride, spraying "920" solution or Jiehai Ling can alleviate the damage.
