Tomato Aphid Control: From Hand-Picking to Chemicals

Aphids on tomatoes. Options by infestation level:

Low Numbers / Small Plants

• Squish by hand.
• Strong water spray (target leaf undersides).

High Numbers / Large Plants

Chemical control needed. Coat upper and lower leaf surfaces.

• Organic: Insecticidal soap, neem extracts, pyrethrins.
• Synthetic: Dimethoate, endosulfan (check local regulations).

Key Points

• Follow label exactly—phytotoxicity risk.
• Reapplication likely needed.
