These Regulations revoke and replace Article 52 of Regulation (EC) No 1107/2009 of the European Parliament and of the Council concerning the placing of plant protection products on the market (EUR 2009/1107, “the 2009 Regulation”) and modify transitional provisions in paragraph 14(4)(b) of Part 4 of Schedule 1 to the Plant Protection Products (Miscellaneous Amendments) (EU Exit) Regulations 2019 (S.I. 2019/556, “the 2019 Regulations”). The 2009 Regulation and the 2019 Regulations concern legislation in the field of pesticides and in particular plant protection products. Both the 2009 Regulation and Part 4 of Schedule 1 to the 2019 Regulations are secondary retained EU law within the meaning of section 11(2) of the Retained EU Law (Revocation and Reform) Act 2023 (c.28). These Regulations also amend the Plant Protection Products Regulations 2011 (S.I. 2011/2131) in consequence of the replacement of Article 52 of the 2009 Regulation and make saving provision in respect of Article 52 of that Regulation.
