How much dry copper fungicide do I use for spraying roses?

Answer:

According to the manufacturer's product label, to apply Bonide Copper Fungicide as a spray to roses, add 8 oz. of product to water and strain.  Then, add that solution to 3 gallons of water to cover 1,000 sq. ft. of area, while continuing to agitate your sprayer to prevent the nozzle from clogging.  Thoroughly spay upper and lower surfaces of foliage to the point of runoff, but do not overspray.  Please refer to the linked product label above, and use as directed.
