Tomato yellow leaf curl virus (TYLCV)
Symptoms
Young leaves yellow between veins and curl upward; plant is stunted; whiteflies may be present.
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 plants, control whiteflies with insect-proof seedlings, reflective mulch or screens where appropriate, and resistant varieties. Manage weeds and avoid moving whiteflies between plantings. There is no curative pesticide.
P. persimilis: allowed / avoid
*N/A - No foliar pesticide applied*
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.
