Aphid Control in Tomato

Aphids colonise tomato growing points and leaf undersides, sucking sap, deforming new growth and — most damaging — vectoring viruses. Their honeydew fuels sooty mould that further cuts photosynthesis and downgrades fruit.

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

Act at first colonies on growing points, before populations and virus spread build.

What to look for

  • Clusters on shoot tips and leaf undersides
  • Curled, distorted new growth
  • Sticky honeydew and black sooty mould
  • Virus-like symptoms from feeding transmission

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.
