Common crops affected
- Cabbage
Why it matters
Diamondback moth is the number-one pest of cabbage worldwide and the most resistance-prone, riddling leaves and contaminating heads.
When it appears
On young larvae before heads form; scout undersides and use pheromone traps for flights.
How to identify it
- Small green larvae that wriggle and drop on a silk thread when disturbed.
- 'Windowpane' feeding (one leaf surface left intact) progressing to shot-holes.
- Damage and frass in growing points and heads, contaminating produce.
How to manage it
- Apply Larva Control at early-instar stage with good underside/growing-point coverage;
- rotate modes of action to manage resistance.
- Monitor early, treat at the right window above, and use cultural measures (sanitation, airflow/drainage or resistance/rotation as relevant).
