DiseaseProblem 05 / 32
Gray mold (Botrytis)
Symptoms
Soft brown lesions on leaves, stems, flowers, or fruit with characteristic gray fuzzy mold; rapid rot in humid conditions.
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
Remove infected tissue and senescent flowers, sanitize tools, reduce humidity, and improve airflow. Avoid wounding fruit.
Product / label options
PRODUCT / LABEL OPTIONS: If necessary, use a labeled product such as cyprodinil/fludioxonil or boscalid, rotating FRAC groups.
Active ingredients
boscalid + pyraclostrobinboscalid + trifloxystrobinfenhexamidpyrimethanilcyprodinil + fludioxonilmepanipyrimpenthiopyradisofetamidfenpyrazaminefluopyram + pyrimethanilthiophanate methylcyprodinil + tebuconazolepyrimethanil + fludioxonilbacillus subtiliscopper hydroxide
Organic active ingredients
bacillus subtilis
P. persimilis: allowed / avoid
PERSIMILIS STATUS: IPM USE WITH INTERVAL. Listed with a short pre-release interval; avoid untested combinations and verify the exact formulation.
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.
