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 and tomato crops for a temporary period beginning with immediate effect and terminating on 31 December 2018.
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.
A temporary approval for the use of Cuprokylt on potato crops during 2017 was granted by The Minister in a March 2017 decision. This approval serves to extend the authorisation to include the 2018 calendar year and to extend the use to include tomatoes. In the U.K., Cuprokylt (marketed by Certis U.K.) currently has full approval status for use on grape crops and temporary authorisation status for use on potato and stone fruit crops; until the end of 2016, Cuprokylt had full approval status for use on potato and tomato crops but this use was withdrawn for commercial reasons. Historically, Cuprokylt was used in Jersey for many years, predominantly 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grown tomato and Jersey Royal potato crops but since the full approval status for use on tomato and potato crops was withdrawn, organic growers have had no fungicides available with which to control late blight.
The 2017 U.K. emergency approval of Cuprokylt by the Chemicals Regulation Division (CRD) for use on potatoes was gained with the approval of the Soil Association and was welcomed by the organic sector in Jersey. A number of growers in the organic and conventional sectors have requested that the authorisation is renewed with immediate effect to include the whole of the 2018 calendar year and extended to include tomatoes. The use of Cuprokylt is not seen as contentious because the active ingredient, copper oxychloride, does not readily leach and poses a low environmental risk. Jersey Water confirm that they do not envisage an issue with its use in Jersey.
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.
