European Union - Final Regulatory Action
Beta-cypermethrin CAS number:
52315-07-8
Date circular:
12/12/2019

Chemical name: A reaction mixture comprising two enantiomeric pairs in ratio ca. 2:3 of (R) -a-cyano-3-phenoxybenzyl (1 S)-cis-3-(2,2- dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate and (S) -a-cyano-3-phenoxybenzyl (1 R)-cis-3-(2,2- dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate with (R) -a-cyano-3-phenoxybenzyl (1 S)-trans-3-(2,2- dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate and (S) -a-cyano-3-phenoxybenzyl (1 R)-trans-3-(2,2- dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate

Final regulatory action has been taken for the category: Pesticide

Final regulatory action: The chemical is Banned

Use or uses prohibited by the final regulatory action:

All applications as a plant protection product.

The final regulatory action was based on a risk or hazard evaluation: Yes

Summary of the final regulatory action:

It is prohibited to place on the market or use plant protection products containing Beta-cypermethrin. Beta-cypermethrin is not included in the list of approved active substances under Regulation (EC) No 1107/2009. As a consequence, Beta-cypermethrin is not approved for placing on the market pursuant to Regulation (EC) No 1107/2009 concerning the placing of plant protection products on the market. Disposal, storage placing on the market and the use of existing stocks of plant protection products containing Beta-cypermethrin is prohibited as of 27 September 2017.

The reasons for the final regulatory action were relevant to: Human health and environment

Summary of known hazards and risks to human health:

It was concluded that no plant protection product containing the active substance Beta-cypermethrin is expected to satisfy in general the requirements laid down in Article 29(1) of Regulation (EC) No 1107/2009 and the uniform principles laid down in Regulation (EC) 546/2011.
The information available for beta-cypermethrin was insufficient to satisfy the requirements set out in the Regulation (EC) No 544/2011 as regards the data requirements for active substances and Regulation (EC) No 545/2011 as regards the data requirements for plant protection products, in particular with regard to information on the toxicity profile of metabolite PBA (3-phenoxybenzoic acid) and its relevance for the consumer risk assessment.

Expected effect of the final regulatory action in relation to human health:

Reduction of risk for human health from the use of plant protection products containing beta-cypermethrin.

Summary of known hazards and risks to the environment:

It was concluded that no plant protection product containing the active substance Beta-cypermethrin is expected to satisfy in general the requirements laid down in Article 29(1) of Regulation (EC) No 1107/2009 and the uniform principles laid down in Regulation (EC) 546/2011.
According to the evaluation related to environment the following concerns were identified:
-a high risk to aquatic organisms, bees and non-target arthropods.
The information available for Beta-cypermethrin was insufficient to satisfy the requirements set out in Article 4(1) to (3)
of Regulation (EC) No 544/2011 in particular as regards the data requirements for active substances, and Regulation (EC) No 545/2011 as regards the data requirements for plant protection products, in particular with regard to:
- the fate and behaviour of the cycloprpyl ring moiety of Beta-cypermethrin in soil under illuminated conditions such that the environmental risk assessment for soil and aquatic organisms could not be finalised nor could the groundwater exposure assessment for any transformation products that may be formed from this portion of the molecule;
- information on the metamolism in livestock for the cyclopropyl moiety in order to confirm the residues definition for animal matrices.

Expected effect of the final regulatory action in relation to the environment:

Reduction of risk for the environment from the use of plant protection products containing Beta-cypermethrin.

Date of entry into force of the final regulatory action: 06/09/2017
