Tea Scale on Euonymus: Spray Schedule and Spreader-Sticker

Tea scale on euonymus requires a multi-year program. Damaged leaves persist, so visual improvement lags behind control.

Spray Protocol

• Start in April. Spray every 2 weeks for 2–3 applications.
• Fall treatment if heavy infestation.
• Add spreader-sticker. Direct spray to leaf undersides.

Effective Chemicals

• Dimethoate (Cygon 2E): 2 tsp/gal
• Acephate (Orthene): 1 Tbsp/gal

Key to Success

Coverage on leaf undersides is critical. Tea scale hides there. Persistence over 2–3 years brings population to manageable levels.
