I purchased CuPRO to use both as a preventative and to treat blackspot. I am not able to determine from the label how much I should use per gallon of water. Actually, I find the instructions hard to comprehend--since it uses acres an so forth. Have others said the same thing? My concern is that I do not want to use too much or too little.
CuPRO 5000 DF Fungicide is a professional product and the label may be difficult to understand. Like most fungicides and herbicides, the amount of water is not important as it acts as a carrier. You will mix 1 1/2 tsp in no less than 1-2 gallons of water. Per the label, the product can cause discoloration of foliage and/or blooms on some varieties of roses. Popular choices for black spot on roses that come in smaller quantities would be Brandt Consan Triple Action 20, or Bayer Advanced Disease Control for Roses, Flowers and Shrubs Concentrate.
