In the domestic fungicide market, there are fewer registered drugs for the control of bacterial diseases than the fungal diseases. In China, inorganic copper preparations are in a supporting role in the prevention and treatment of bacterial diseases. The organic copper preparation thiabium copper (Dragonella) is the protagonist and has become an ideal choice for many large planters. So how can the thiabend copper be used to its fullest effect? ​​The thiazide copper compounding technology of the following diseases hopes to help you!
