Definition of Powdery Mildew

Powdery mildew is a common fungal disease that affects a wide variety of plants. It appears as a white or gray powdery coating on the leaves and stems.

This fungus thrives in warm, dry climates with cool nights, which can make rosemary, a plant that enjoys similar conditions, susceptible.

Impact on Rosemary Plants
