Analyzed September 4, 2026
Primary Diagnosis
Bacterial Blight (Xanthomonas axonopodis pv. dieffenbachiae)
Diagnostic note
The leaf shows classic symptoms seen in Anthurium bacterial blight, featuring an expanding necrotic lesion surrounded by a bright chlorotic (yellow) zone. Early fungal leaf spots (Anthracnose) and root damage from overwatering can produce similar secondary foliar necrosis and require careful monitoring of watering habits.
What the AI detected
- Severe yellow chlorosis across leaf surface
- Large dark brown to black necrotic central lesion
- Water-soaked brownish speckling near lesion borders
- Interveinal yellowing pattern progressing from margin/center
Alternative possibilities
Treatment plan
- 1Isolate the plant immediately to prevent spray-transmission to healthy plants
- 2Prune and dispose of affected leaf using sterilized cutting tools
- 3Eliminate overhead watering and keep leaves dry
- 4Increase ambient air circulation around the foliage

Photo tips for better accuracy
Diffuse natural light
Shade or overcast is best — direct sun creates glare that hides lesion detail.
Frame the affected area
Fill the frame with the sick leaf. More detail = more accurate result.
Plain background
White or neutral surface behind the leaf reduces visual noise.
Multiple angles
If symptoms are subtle, try 2–3 shots from slightly different angles.
