# Commission Implementing Decision (EU) 2017/1532 of 7 September 2017 addressing questions regarding the comparative assessment of anticoagulant rodenticides in accordance with Article 23(5) of Regulation (EU) No 528/2012 of the European Parliament and of the Council (Text with EEA relevance), Division: Question (a): Is the chemical diversity of the active substances in authorised rodenticides in the EU adequate to minimise the occurrence of resistance in the target harmful organisms?

Extent: E+W+S+N.I.

There are five approved active substances in biocidal products for product-type 14 with a mode of action different from that of anticoagulant rodenticides (alpha chloralose, aluminium phosphide releasing phosphine, carbon dioxide, hydrogen cyanide and powdered corn cob).
According to the opinion, the minimum requirement in agreed Union guidance of having three different alternatives with a different mode of action is not reached for any of the specified uses listed in Table 1. Therefore, in the absence of anticoagulant rodenticides, the condition in Article 23(3)(b) of Regulation (EU) No 528/2012 that the chemical diversity of the active substances is adequate to minimize the occurrence of resistance in the target harmful organisms is not met.
