Common crops affected
Why it matters
They reduce leaf area and blemish fruit, downgrading pack-out; populations build through overlapping generations.
When to act
Target young larvae at each generation, before they roll leaves and scar fruit.
What to look for
- Rolled, webbed leaves sheltering larvae
- Chewed leaf and fruit surfaces
- Russeted feeding scars on fruit
- Two or more generations per season
How to manage it
- Use pheromone traps to time sprays to egg hatch.
- Apply Larva Control at the start of larval activity; rotate with Larva BioControl.
