DISEASE CHARACTERISTICS
A fungus disease which causes foliage to develop black circular spots. The leaves become stressed and begin to turn yellow, then wither and drop off. New leaves may be produced, but these will develop black spot as well.

PREVENTION
• Pinch off and dispose of any affected leaves as they occur.
• Keep rose foliage as dry as possible, as the disease is spread by
splashing water.
• Remove leaves in late fall, and rake up fallen leaves from around the base of plants.
• Spray canes with dormant oil and lime sulfur before plants leaf
out in spring.

CONTROL
Apply any of the following sprays-
• Sulfur
• Benomyl
• Folpet
• Bordo Copper Spray
• Fungicides must be applied before the fungus becomes
established to be most effective. (to print, right-click on this page)
