Cuprokylt (copper oxychloride) Temporary Authorisation Report
(Public)
Purpose of the Report
The Minister for the Environment (The Minister) is requested to:
- Approve the sale, dispersal, storage and use of Cuprokylt (copper oxychloride) as a fungicide on potato crops for a temporary period terminating on 12 September 2017.
Background
The Pesticides (General Provisions) (Jersey) Order 1991, article 4, enables the Minister at any time to give his approval, or amend the conditions of an approval, in relation to a pesticide of any description.
In the UK, Cuprokylt (marketed by Certis U.K.) has full approval for use on grape crops. It had full approval for use on potato crops until the end of 2016 but this use was withdrawn for commercial reasons. Cuprokylt was used in Jersey for many years, predominantly for the control of late blight in organically grown Jersey Royal potato crops. Its use was endorsed by the Soil Association. Since the authorisation for use on potato crops was withdrawn, organic growers have had no fungicides available with which to control late blight.
The U.K. emergency approval of Cuprokylt by the Chemicals Regulation Division (CRD) on potatoes for the period of 120 days commencing 15 may 2017 has been gained with the approval of the Soil Association. This has been welcomed by the organic sector in Jersey as it the only fungicide available for the control of late blight on organically grown Jersey Royal (and other) potato crops. A Jersey potato marketing group has asked the UK approval be extended to Jersey with immediate effect to reflect the Jersey earlier growing season.
Supporting Documents
Any person or organisation wishing to use Cuprokylt in Jersey must obtain a “Temporary Authorisation for Cuprokylt” document (as attached to this report) from the Department of the 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.
