African Violet Rescue: Powdery Mildew and Aphid Control

Two separate issues: white powder on leaves = powdery mildew; yellow bugs = aphids (or mealybugs).

Powdery Mildew

1. Remove severely affected leaves.
2. Spray with fungicide labeled for powdery mildew and safe for African violets (e.g., sulfur-based or potassium bicarbonate).
3. Improve air circulation; avoid wetting leaves.

Aphids/Mealybugs

1. Invert plant, swirl in bowl of lukewarm soapy water (1 tsp mild soap/quart) for 30 seconds.
2. Rinse with clean water.
3. Repeat in 7 days.
4. For mealybugs (cottony), touch each with alcohol-dipped swab.

Prevention

• Isolate new plants 2 weeks.
• Water from bottom; keep leaves dry.
• Provide 12+ hours bright, indirect light.
