Cuprokylt (Copper Oxychloride): Temporary Authorisation

A formal published “Ministerial Decision” is required as a record of the decision of a Minister (or an Assistant Minister where they have delegated authority) as they exercise their responsibilities and powers.

Ministers are elected by the States Assembly and have legal responsibilities and powers as “corporation sole” under the States of Jersey Law 2005 by virtue of their office and in their areas of responsibility, including entering into agreements, and under any legislation conferring on them powers.

An accurate record of “Ministerial Decisions” is vital to effective governance, including:

  • demonstrating that good governance, and clear lines of accountability and authority, are in place around decisions-making – including the reasons and basis on which a decision is made, and the action required to implement a decision

  • providing a record of decisions and actions that will be available for examination by States Members, and Panels and Committees of the States Assembly; the public, organisations, and the media; and as a historical record and point of reference for the conduct of public affairs

Ministers are individually accountable to the States Assembly, including for the actions of the departments and agencies which discharge their responsibilities.

The Freedom of Information Law (Jersey) Law 2011 is used as a guide when determining what information is be published. While there is a presumption toward publication to support of transparency and accountability, detailed information may not be published if, for example, it would constitute a breach of data protection, or disclosure would prejudice commercial interest.

Subject:

Temporary Authorisation: Cuprokylt (copper oxychloride).

Decision:

The Minister for the Environment approved the sale, dispersal, storage and use of Cuprokylt (copper oxychloride) as a fungicide on tomato and potato crops for a temporary period, with immediate effect and terminating on 31 December 2022.

Reason for Decision:

The Minister for the Environment made this decision to support organic and conventional tomato and potato growers in Jersey.

 

In accordance with the Pesticides (Jersey) law 1991, the Minister for the Environment may at any time give his approval in relation to a pesticide or amend the conditions of an approval; each approval may authorise the supply, storage and use of the pesticide to which it relates. In addition, the Minister may approve a pesticide which has been authorised for use elsewhere subject to the conditions of use.

Resource Implications:

There are no financial or manpower implications arising from this decision.

Action required:

Officers to:

  1. As soon as reasonably practical, give public notice in the Jersey Gazette of this Ministerial Decision; and
  2. Issue any person or organisation wishing to use Cuprokylt in Jersey a “Temporary Authorisation for Cuprokylt” document.

Cuprokylt (Copper Oxychloride): Temporary Authorisation

 

 

Ministerial Decision Report

Temporary Authorisation: Cuprokylt (copper oxychloride)

 

Background

The Pesticides (General Provisions) (Jersey) Order 1991, article 4, enables the Minister for the Environment (‘the Minister’) at any time to give their approval, or amend the conditions of an approval, in relation to a pesticide of any description.

 

A temporary approval for the use of Cuprokylt on potato crops during 2021 was granted by the Minister (MD-PE-2021-0010) and identical temporary approval has been granted in the previous five years for use on potato and tomato crops.

 

Cuprokylt has been used in Jersey for many years for the control of late blight in organically grown tomato and Jersey Royal potato crops but, since the full approval status for use on tomato and potato crops was withdrawn, organic growers have had no alternative fungicides available with which to control late blight.

 

In the U.K., Cuprokylt (marketed by Certis U.K.) currently has full approval status for use on grape crops and in forestry; until the end of 2016 it also had full approval status for use on potato and tomato crops until this was withdrawn for commercial reasons.

 

Detail

A number of potato and tomato growers in the organic and conventional sectors have requested that the authorisation for Cuprokylt is renewed with immediate effect to include the whole of the 2022 calendar year.

 

The use of Cuprokylt is not seen as contentious by Natural Environment as the active ingredient, copper oxychloride, does not readily leach and poses a low environmental risk. Jersey Water confirm that they have no concerns over its continued use in Jersey, and the use of copper-based fungicides is endorsed by the UK Soil Association.

 

Any person or organisation wishing to use Cuprokylt in Jersey would be required to obtain a “Temporary Authorisation for Cuprokylt” document (see appendix) from Infrastructure, Housing and Environment. The document describes the product, provides advisory information, and sets out the conditions for authorised use, including crop maximum residue levels and spray operator protection requirements.

 

Resource Implications

There are financial or manpower implications arising from this decision.
