Indian Hawthorn Entomosporium: Aggressive Fungicide and Sanitation Protocol

Indian hawthorns with 70% defoliation from Entomosporium leaf spot—requires strong fungicide (chlorothalonil, propiconazole, thiophanate-methyl) + rigorous sanitation.

Treatment Protocol

1. Cleanup FIRST: Remove all fallen leaves — bag/trash, no compost
2. Water management: Drip only, keep foliage dry
3. Spray: Every 7-10 days until clean new growth (month+)
4. Fungicide choice: Chlorothalonil, propiconazole, or thiophanate-methyl — label must list hawthorn leaf spot
5. Coverage: Thorough, top and bottom

Why This Works

Entomosporium spreads via splash. Sanitation removes inoculum; fungicide protects new growth. Cycle breaks in 3-4 weeks with diligence.

Georgia Heat Note

Hot, humid GA summers favor this disease. Ongoing vigilance needed. Resistant varieties help but aren't bulletproof.
