Management-cultural control

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

Management-chemical control: HOME USE

Apply to both tops and undersides of leaves.

• azadirachtin (neem extract)-Some formulations are OMRI-listed for organic use.
• bifenthrin (as a mix with zeta-cypermethrin).
• carbaryl
• imidacloprid
• plant-derived essential oils (rosemary, peppermint etc.)-These have some efficacy against aphids. Some formulations are OMRI-listed for organic use.
• pyrethrins-Some formulations are OMRI-listed for organic use.
• zeta-cypermethrin
