Update on a recent R&D project to investigate de-husking of seeds by small mammals: Implications for regulatory risk assessment

During evaluation of seed treatment applications, CRD ecotoxicologists frequently need to refine the risk assessment to determine whether the risk to mammals is acceptable. In such cases, applicants often use de-husking behaviour to mitigate the risk to mammals, referencing an 85% de-husking value (SANCO/4145/2000).
