Primary Diagnosis
Bacterial Blight (Xanthomonas axonopodis)
Diagnostic note
The presence of a dark necrotic lesion bordered by extensive chlorosis and bronzed spotting on an Araceae (Anthurium/Pothos family) leaf is highly characteristic of Xanthomonas bacterial infection or severe fungal leaf spot. Overwatering and root injury can also trigger rapid yellowing with secondary foliar lesions, so soil moisture levels should be verified.
What the AI detected
- Widespread bright yellow chlorosis on affected leaf
- Large dark brown to black necrotic lesion near margin
- Bronze-brown speckled leaf spots within chlorotic zone
- Surrounding foliage remains mostly green
Alternative possibilities
Treatment plan
- 1Isolate the affected plant from other foliage immediately
- 2Prune and destroy infected leaves using shears sanitized with rubbing alcohol
- 3Improve air circulation around the plant and ensure leaves stay completely dry when watering

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.
