Scale Infestation on Golden Euonymus: Treatment Options

Heavy Scale Attack on Golden Euonymus

White and black bumps covering leaves and branches, causing rapid leaf drop, indicate a severe tea scale infestation. Insecticidal sprays alone failed.

Integrated Approach

1. Prune heavily infested branches; dispose of debris
2. If temps <80°F: apply horticultural oil (Volck) or Orthene
3. Systemic option: Bayer Advanced Tree & Shrub Insect Control (imidacloprid soil drench)
4. Consider replacement if plant is severely declined

Why Scale Is Tough

Scale's protective shells resist contact insecticides. Oils smother them; systemics kill via sap. Timing (crawler stage) and thorough coverage are critical.
