Bush White Mold: Likely Powdery Mildew

One of four bushes with white mold/blight on leaves = likely powdery mildew. Without plant ID/location, this is the best guess.

If Powdery Mildew

• Fungicide: myclobutanil, propiconazole, sulfur.
• Prune for air flow.
• Water at base.
• Rake fallen leaves.

Need More Info

Send: plant name, location, photos (whole plant, close-up of "mold"). Then I can confirm.

Cornell link in original has good powdery mildew info.
