Regulatory Update:  02/2018
Issued:  April 2018

Updating your authorisation

HSE does not routinely notify product authorisation holders where a change or update of a current authorisation is required because of a change by the EC to an approval of an active substance.  Authorisation holders are advised to check the EUR-Lex webpage and the EU Pesticides database where new or changes to active substance approvals and review reports are published.

Active substance approvals

At the Standing Committee on Plants, Animals, Food and Feed (SCoPAFF) it was agreed:

To approve under Regulation (EC) 1107/2009;

Bentazone, forchlorfenuron, propyzamide, silthiofam and zoxamide

These substances were considered under the second and third stages of the renewal programme (governed by Commission Regulations 1141/2010 and 844/2012).  Authorisations for products containing these substances will need to be renewed in accordance with Article 43 of Regulation (EC) 1107/2009, with applications required by 31 August 2018 (forchlorfenuron, bentazone) and 30 September 2018 (propyzamide, silthiofam, zoxamide).  For further information see Guidance on UK Procedures for product renewal applications.


The restriction to use only on ornamental crops was removed.  Part A of approval regulation was consequently amended as follows:

'Only uses as acaricide in greenhouses may be authorised.'


A revised review report was noted with the new toxicological reference values as follows:

Authorisation holders should submit applications by 22 June 2018 in support of 2,4-D product authorisations in light of the above revised reference values.  Member States have until 22 March 2019 to review product authorisations.
