Powdery mildew is most commonly found in which lawn area?

• A. Shaded areas
• B. Full sun
• C. Drought-prone patches
• D. Waterlogged zones

Answer: (A)

Powdery mildew on turf favors cool, humid, low-airflow conditions. When grass grows in shaded spots, the leaf surfaces stay moist longer and air movement is limited, creating a microclimate where fungal spores can germinate and spread more easily. In full sun, heat and quick drying of the blade surface make these conditions less favorable for the fungus. Drought-prone patches and waterlogged zones can stress turf or create other issues, but they don’t provide the steady, moist shade that this disease thrives in. So shaded areas are the most common site for powdery mildew on lawns.
