Introduction

Non-target arthropods play a vital role in the ecosystem, and therefore pesticide products that are used as prescribed should not cause unacceptable effects on populations of non-target arthropods both in- and off-field. Many species of non-target arthropods are natural enemies of pests. Their presence and healthy activity keeps primary and secondary pests in check. The objective of the assessment is therefore to ensure that any risk to non-target arthropod populations, both within and off the cropping field, are highlighted and to assess the nature of the risk so that adequate risk reduction measures can be taken.
