Green peach aphid

Written by   Orchard plant protection guide

Outbreaks of the green peach aphid in spring are usually associated with good growing conditions.

Aphid populations can be reduced by hot, dry winds and conditions which harden tree growth.
Non-pesticide management
A number of biological control agents can reduce aphid populations and should be encouraged.
Avoid using pesticides which will kill these biological control agents.
Avoid excessive amounts of nitrogen fertilisers which promote growth of soft plant tissue, and prune out water shoots.
Control weeds around the orchard as these act as reservoirs for migrating aphids.
