  • FIND – look for aphids and the characteristic plant symptoms of leaf streaking or leaf rolling on cereal crops and grasses
  • IDENTIFY – positively identify the pest in consultation with a specialist
  • THRESHOLD APPROACH – consider international thresholds for control, factoring crop growth stage and potential yield losses
  • ENACT an appropriate management strategy that where possible preserves beneficial insects.
