For pesticide formulations, the UK Chemical Regulation Division currently authorised pesticide database was accessed on 28/04/2022 (CRD, 2022b). Products are authorised on a rolling basis, so the authorised products in the database can change regularly. However, approvals are for up to ten years, so the turnover will be slow. The database was searched twice, once for professional formulations, once for amateur formulations. The web-based table was copied and pasted into Excel . The dataset contained formulation name, registration number, authorisation expiry date, marketing company, authorised crops, whether the formulation was authorised in Great Britain, Northern Ireland or both, as well as the active ingredients (but not their concentration).
