Euonymus Scale Persistence: Dead Scale Recognition and Neem Oil Alternative

Current Status

Diane's euonymus: sprayed dormant oil for scale. Now brown dots covering barky limbs — new pest or dead scale?

Dead Scale Test

• Press fingernail into brown dots
• Liquid/bleed = alive
• Dry/crumbly = dead (already controlled)
• Dead scale doesn't fall off automatically
• Can scrape off manually

Neem Oil Recommendation

Pure Neem Oil (Dyna-Gro) — Kathy's preferred alternative:

• Pure, safe, non-washing
• Best for most plant problems
• Builds residual protection
• Multi-action: insecticide, fungicide, miticide

Why Dormant Oil Struggles

Contact-only, timing-critical, coverage-dependent. Systemic or translaminar products (like neem's absorbed protection) more reliable for scale.
