If effective control measures are not applied, the apple fruit rhynchites weevil can build up to high levels and cause serious damage (> 50% fruits infested).
- It can be very destructive in organic orchards where the only cultural control measure is to manage alternative hosts. However, it seems that although infestations are often associated with adjacent hawthorn, this is not always the case.
- Before 2021, apple fruit rhynchites weevils could be controlled in organic orchards by one or more sprays of pyrethrins (Pyrethrum 5 EC) targeted against adults after blossom. In 2021, AHDB has been seeking an EAMU authorisation for Spruzit (pyrethrins) for use on apple.
