UK: Emergency approval granted for organic potato blight product

Emergency approval granted for CuprokyltA breakthrough emergency authorisation for Cuprokylt (copper oxychloride) provides the only fungicide available to organic potato growers in Britain for the control of late blight, at a key time of the season. The Extension of Authorisation for Minor Uses (EAMU) was driven by industry leading stakeholders, including Certis, Agrii, the Agriculture and Horticulture Development Board (AHDB), National Farmers’ Union and several organic growers associations. “Being able to utilise copper oxychloride will support organic growers and help them to capitalise on market demand,” said Nick Winmill, Agrii Potato development manager. 

“Without copper, only cultural control methods are available for the control of late blight in organic potatoes, and as a result, it’s been difficult to keep varieties with preferential qualities blight free.” Winmill warned that if another extension isn’t secured for copper oxychloride, or if an alternative isn’t found for use in organic potatoes, then production will only become more difficult in the future.
