In the process of growth and development of cotton, due to the variety of pests and diseases, it is necessary to repeatedly and repeatedly carry out pesticide control; once applied improperly, it is easy to cause phytotoxicity to cotton, but it will affect growth and development, and plant metamorphosis or even death in severe cases. The remedy for cotton after phytotoxicity is: 1. Rinse. Most chemical agents are not resistant to water scouring. If the drug is found to be improperly used, it can be sprayed with water on the sprayer and sprayed repeatedly to wash away the residue on the surface of the cotton plant to reduce the phytotoxicity. When flushing, the pressure of the sprayer should be The amount of water sprayed is large. For the phytotoxicity caused by the cotton field applied by soil and some herbicides , the soil can be immediately washed and the residual agent can be drenched into the deep layer of the soil. 2. Fertilizer. Generally, the phytotoxicity of the symptoms such as leaf spot, leaf edge scorch, and plant yellowing can be alleviated by applying fertilizer or foliar application of Green Wind 95, Gaomei Shi, Plant Power 2003, Tianda 2116, etc. Degree of harm. For example, when cotton seedlings have 2,4?d butyl phytotoxicity, the appropriate amount of quick-acting nitrogen fertilizer can be applied to promote hair growth and hair growth, so that the cotton plant can resume normal growth and development as soon as possible. 3. Chemical control. Phytotoxicity of some herbicides, plant growth regulators caused by spray can be targeted to plant growth regulator reverse adjusted after injury. If cotton seedlings are affected by 2,4?d phytotoxicity, foliar application with 30~50ppm gibberellin solution can obviously promote the growth of plants; when cotton produces chlormequat, spray "920" solution, Relieve phytotoxicity. 4. Thin tube. After the phytotoxicity of cotton, timely removal of chlorotic and metamorphic branches and leaves can reduce the penetration and conduction of the agent in the plant; timely cultivation of loose soil, appropriate application of phosphorus and potassium fertilizer can promote root development and enhance the resistance of cotton plants. .
