Leaf mold
Symptoms
Olive-green to brown velvety patches on the upper leaf surface; dense olive/gray mold on the underside; yellowing and premature leaf drop.
How to verify
Compare the photos above with the plant, and check the symptom description against the look-alike records below before acting. The source guide does not carry a separate laboratory verification note for this record.
Next step
Reduce humidity, increase spacing and ventilation, and remove infected leaves. Use drip irrigation.
Product / label options
PRODUCT / LABEL OPTIONS: If needed, apply a tomato-labeled product such as difenoconazole or azoxystrobin according to the label and rotate modes of action.

Label matters
Active ingredients below are examples, not universal prescriptions. Confirm the diagnosis; use only products registered for tomato and the target problem in your country; and follow the current label for dose, pre-harvest interval, worker protection, compatibility and re-entry. Rotate IRAC/FRAC modes of action. When symptoms are uncertain, obtain a laboratory or extension diagnosis. Integrated pest management (IPM)—sanitation, resistant varieties, irrigation management, monitoring and biological control—should be the first line of defense.
