The original drug is blue powder and is a protective broad-spectrum fungicide. After preparation, the solution is stable and has good diffusivity. After spraying, it has strong adhesion, is resistant to Rain Water erosion, and can release copper ions stably and slowly, which is generally not easy to cause drug damage to crops and is safe to human beings and animals.
