Which symptom is associated with powdery mildew on infected leaves?

• A. Leaves turn yellow and wither
• B. Leaves turn blue
• C. Leaves experience necrotic tips only
• D. Leaves show no visible symptoms

Answer: (A)

Powdery mildew presents as a white, powdery coating on leaf surfaces. That fungal growth blocks light and interferes with photosynthesis, stressing the leaf tissue. As infection deepens, chlorophyll is lost and the leaves often yellow and wither, especially on severely infected plants. So among the options, yellowing and withering aligns with how a once-healthy leaf declines under a significant powdery mildew infection. The other descriptions don’t fit: blue leaves aren’t a typical symptom, necrotic tips alone aren’t the common signature of this disease, and powdery mildew is usually visible rather than completely absent.
