Cotton medicinal damage

Flushing, most chemicals will become lighter under the scouring of water. If the drug is found to be improper when used, it can be sprayed with water to spray the leaves repeatedly to wash away the pesticide remaining on the surface of the cotton plant. Reduce the phytotoxicity; the amount of water during rinsing should be large. The cotton field applied with soil is immediately irrigated with water to reduce the residual amount of the drug.

Fertilization, generally for the production of leaf plaques, leaf edge scorch, plant yellowing and other symptoms of phytotoxicity, the application of fertilizer or foliar spray of new high-lipid film to increase resistance to reduce the degree of phytotoxicity.

Physical regulation, for some herbicides, plant growth regulators caused by phytotoxicity, can be targeted to spray plant growth regulators for reverse regulation. If the cotton seedling is affected by auxin, the foliar spray with gibberellin solution may promote the growth of the plant.

For the general cotton phytotoxicity, timely remove the chlorotic, metamorphic branches and leaves, timely cultivating the loose soil, appropriate application of phosphorus and potassium fertilizer to enhance the resistance of the cotton plant.
