Management-cultural control

Aphid populations tend to be higher in plants that are fertilized liberally with nitrogen.

Home gardeners can use row covers or wash aphids from plants with a strong stream of water.

Management-chemical control: HOME USE

  • acetamiprid
  • azadirachtin (neem oil)-Some formulations are OMRI-listed for organic use.
  • bifenthrin (often as a mix with zeta-cypermethrin).
  • capsaicin-Some formulations are OMRI-listed for organic use.
  • carbaryl
  • cyfluthrin
  • deltamethrin
  • esfenvalerate
  • gamma-cyhalothrin
  • horticultural oil-Some formulations are OMRI-listed for organic use.
  • imidacloprid
  • insecticidal soap-May require several applications. Some formulations are OMRI-listed for organic use.
  • lambda-cyhalothrin
  • malathion
  • permethrin
  • plant essential oils (rosemary, thyme, etc.)-Some formulations are OMRI-listed for organic use.
  • pyrethrins-Some formulations are OMRI-listed for organic use.
  • zeta-cypermethrin
