Last Updated: 2024/11/05, Copper noble 27.12% basic copper sulfate suspension can be used to control many diseases of cotton. After sowing and covering the soil of medicated cotton at seedling stage, it was poured with copper noble 27.12% basic copper sulfate suspension 600 × 800 times to disinfect the seedbed soil and effectively prevent soil-borne diseases. When cotton seedlings are neat and cotyledons are spreading, spraying 1000 times of copper noble 27.12% basic copper sulfate suspension can effectively control cotton seedling diseases such as blight and anthracnose.

Copper noble 27.12% basic copper sulfate suspension can be used to control cotton diseases.

After sowing and covering the cotton with soil-applied fertilizer at seedling stage, 600~800 times solution of copper noble 27.12% basic copper sulfate suspension was poured to disinfect the seedbed soil and effectively prevent soil-borne diseases. Cotton seedling diseases such as seedling blight and anthracnose can be effectively controlled by spraying 1000 times solution of copper noble 27.12% basic copper sulfate suspension when cotton seedlings are fully grown and cotyledons are flat. 3~5 days before transplanting, spraying 1000 times solution of copper noble 27.12% basic copper sulfate suspension can ensure that transplanted cotton seedlings will not be infected and improve the survival rate of transplanting.

Cotton Fusarium wilt is a soil-borne systemic disease, which is easy to be infected when the temperature and humidity are suitable. After cotton seedlings are infected, spray 600~800 times solution of copper noble 27.12% basic copper sulfate suspension at the initial stage of disease, and reapply once every 7~10 days. The plants with serious disease can be irrigated with 500 times solution of copper noble 27.12% basic copper sulfate suspension. Cotton angular spot disease was caused by bacterial infection after flooding. Spraying 500 times solution of copper noble 27.12% basic copper sulfate suspension at the initial stage of disease could effectively control the spread of disease.

The medicine has no systemic property, can not inhibit the growth of cotton plants due to excessive use times, has strong adsorption power and permeability, and has an effective period of more than 20 days. Early medication is better for prevention. It has good compatibility and can be mixed with fungicides and pesticides other than strong acids and strong bases, but not with domestic potassium dihydrogen phosphate. If necessary, it can be mixed with Neufamum Dorica (high content foliar potassium fertilizer, containing nitrogen, phosphorus and trace elements) or high quality foliar fertilizer and regulator.
