Blackspot: This fungal disease causes black spots to form on the leaves, eventually causing them to drop. It can be prevented by planting roses in a location with good air circulation and avoiding overhead watering.
Powdery Mildew: This fungal disease appears as a white powdery coating on the leaves. It can be treated with a fungicide, but prevention is best achieved by providing good air circulation and avoiding overhead watering.
