Azalea Bud Damage: Ants, White Powder, and Tiny Leaves — Diagnostic Links for Pest/Disease ID

Symptom Cluster

• Buds don’t open; infested with tiny ants.
• White powder around buds.
• Leaves around buds tiny, tightly knit.
• Fire ant treatment and Sevin dust failed.

Likely Issues

• Azalea lace bug — causes stippling, but not bud infestation.
• Flower blight (Ovulinia) — brown, mushy buds.
• Ants farming aphids/scale — honeydew → sooty mold (black, not white).
• Powdery mildew — white powder on leaves/buds.
