Dip a pair of bypass shears into a mixture of 70 percent denatured alcohol and 30 percent water to prevent spreading the fungal spores. Make sure that you sterilize the pruning tool every time you make a cut.

2
Remove infected leaves from the plant. Cut back heavily infected stems by making 45-degree downward-angled cuts back to healthy outward-growing stems.

Remove mulch around the rose plant that may be harboring the fungal spores. Burn or throw away infected mulch and diseased debris. Avoid placing the debris in your compost.

4
Water your rose plant at its dripline. The dripline is the area that is directly underneath the outermost branches of the plant. Overhead watering can help contribute to the disease.

Wipe leaves off with a soft towel if they are wet from surrounding irrigation or dew in the late afternoon. Wet leaves and cool nighttime temperatures may encourage fungal growth.

Tips & Warnings
Plant rust-resistant rose varieties in your garden.
Avoid getting water that has touched infected leaves on other areas of your rose plant, because the fungus spreads through water.
