fungal leaf spot on Alocasia Frydek
Quick answer
If your Alocasia Frydek has fungal leaf spot, the most likely cause is: Fungal leaf spot infection (likely Cercospora or similar pathogens) on Alocasia Frydek is triggered by prolonged leaf wetness from standing water or droplets. The velvety leaf texture retains moisture poorly in stagnant high-humidity indoor environments, creating ideal conditions for foliar fungal pathogens. This distinguishes from root issues like rot.
Start here:
- 1. Isolate the plant immediately to prevent spread to other tropicals
- 2. Apply a copper-based fungicide like Garden Safe or Captain Jack's Deadbug Brew, following label dilution and reapplication schedule (every 7-14 days)
