Most chemical agents are not water-resistant, and if they are found to be improperly applied, they can be sprayed with water to spray the leaves repeatedly to wash away the residues remaining on the surface of the cotton plant to reduce the harm; when washing, the sprayer The air pressure is sufficient and 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. Fertilizer generally produces phytotoxicity such as leaf plaque, leaf edge scorch, plant yellowing and other symptoms, adding fertilizer or foliar application of Green Wind 95, Gaomei Shi, Plant Power 2003, Tianda 2116, etc. Reduce the degree of phytotoxicity. For example, when 2,4-D butyl ester phytotoxicity occurs in cotton seedlings, appropriate amount of available nitrogen fertilizer can be applied to promote hair growth and hair growth, so that cotton plants can resume normal growth and development as soon as possible. Chemical control of some herbicides, plant growth regulators caused by phytotoxicity, can be targeted after the phytotoxicity of plant growth regulators for reverse regulation. 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.
