Chemical control of apple grass aphid is usually not attempted in organic orchards because the pest only causes minor damage which is tolerated.
- Emphasis should be placed on cultural control measures such as the provision of artificial refuges for earwigs and lacewings and of flowering herbs in and around the orchard to encourage predatory insects.
- High volume sprays of fatty acids could be applied when damaging infestations develop if necessary on more sensitive varieties.
- Pyrethrins (Pyrethrum 5 EC) was previously approved for use in organic orchards but permission had to be sought from certification bodies before use. The approval for use of pyrethrins was revoked on apple and stocks should have been used up by 31 May, 2020.
