Non-Chemical Management
- Provide proper plant culture. Healthy plants can tolerate more insect damage.
- Avoid overfertilization. High levels of nitrogen in the foliage encourages aphid reproduction. Switch to a slow-release or low-nitrogen formula if necessary.
- Hose infested trees with a strong stream of water to wash off insects.
- Where practical, prune and destroy individual, heavily-infested branches.
- Encourage natural aphid predators, including ladybird beetles and green lacewings.
