Cotton phytotoxicity control measures

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 improper, it can be sprayed with water on the sprayer and sprayed repeatedly on the stems and leaves to wash away the residues remaining on the surface of the cotton plant to reduce the harm. 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, it produces phytotoxicity such as leaf spot, leaf edge scorch, and plant yellowing, and applies fertilizer or foliar spray to apply new high-fat film to isolate pests and diseases, inhibit pests and diseases, and reduce the degree of phytotoxicity. For example, when cotton seedlings have phytotoxicity, they can apply appropriate amount of quick-acting nitrogen fertilizer and new high-fat membrane to improve the utilization rate of effective components of nutrient fertilizer, promote hair growth and hair growth, and restore cotton plants to normal growth and development as soon as possible.

3. Chemical control. For the phytotoxicity caused by some herbicides and plant growth regulators, the plant growth regulator can be sprayed in a targeted manner for reverse adjustment after the phytotoxicity. Spraying Huahua No. 3 can transform plant vegetative growth into reproductive nutrition, inhibit the main shoots from becoming mad, and promote flower bud differentiation.

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. .
