Diagnosing Copper-Colored Spots on Eugenia: Likely Guava Disease

Your Eugenia (likely a guava relative) has raised copper-colored circles on leaves, with older leaves yellowing and dying. Local nurserymen say it's widespread in Palm Beach County with no known cure. A UF Extension contact identified it as a guava disease.

Symptoms alone can't confirm a virus or specific pathogen. The UF/IFAS Plant Diagnostic Center in Gainesville can analyze a physical sample and give a definitive diagnosis. This is critical—several diseases attack guava, and treatment depends on the exact cause.

Next Steps

• Contact your county extension office to submit a sample (leaves, stems, roots).
• Do not apply treatments until you have a confirmed ID.
• If it's a virus, there is no cure—infected plants should be removed to prevent spread.

Working through the extension service is the right move. They'll guide you on sampling, shipping, and interpreting results. Accurate diagnosis saves time, money, and potentially other plants.
