No, Cupro 5000 DF is not labeled for black raspberries. It is labeled for ornamentals. We would recommend using Liquid Copper Fungicide. With this product, you will use 0.5 to 2.0 fl. oz. per gallon of water. You will use this every 7-10 days until harvest. Please let us know if you have any additional questions.
