Preferred Method: The difenoconazole copper complex is obtained by adding an organic solvent into difenoconazole in a ratio of 1:(4-7), heating and stirring to dissolve, heat to 90 plus minus 2 degrees C to add copper salt, where the molar ratio of the inorganic copper salt to difenoconazole is 1:(1-2), heating and marinating the temperature at 60-120 degrees C, stirring to maintain the reaction for 2.5-3 hours, and cooling with cold water to 20 plus minus 2 degrees C, filtering and drying at 50-60 degrees C. ACTIVITY - Fungicide; Antibacterial.
