Aphids
Symptoms
Soft-bodied insects cluster on new growth and leaf undersides; curling, honeydew, and sooty mold occur.
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
Use water spray, remove heavily infested tips, conserve lady beetles and parasitoids, and avoid unnecessary broad-spectrum sprays. If thresholds justify treatment, use a labeled product such as flonicamid, acetamiprid, spirotetramat, or another registered option.

LABEL CHECK: Confirm the aphid species and protect pollinators and beneficials; follow the local label and pre-harvest interval.
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.
