It is recommended to increase functional biodiversity within the orchard (e.g. by practicing an alternating mowing regime with a permanent supply of flowering plants as food sources for beneficials notably in early spring):

  • Plants species that form the vegetation cover should be native or be selected/planted due to its favourable characteristics for beneficials.
  • IP guidelines should provide a list of preferred plant species. This list should consider and possibly avoid known host plants of destructive new pests (e.g. Halyomorpha halys), as well as disease (e.g. fireblight); hawthorn should be as well avoided as a host of potential vector of the apple proliferation.
