Aphid Control in Pepper

On pepper, aphids cluster on tender growth and under leaves, stunting plants, sticking the canopy with honeydew and spreading viruses that can undercut a whole crop. Protected culture lets populations run year-round.

Common crops affected

Why it matters

Beyond feeding damage they are the top insect virus vectors, and colonies explode within a week, so early control protects both vigour and against virus spread.

When to act

Treat at first sign on growing points; scout undersides weekly in protected culture.

What to look for

  • Colonies on new growth and leaf undersides
  • Leaf curl and stunting
  • Honeydew and sooty mould
  • Virus symptoms from feeding

How to manage it

  1. Encourage ladybugs and lacewings; avoid excess nitrogen.
  2. Hose off light colonies.
  3. Spray Spider Mite Control at 1:500 on both surfaces; repeat every 3–5 days.
