Potato growers are facing into this season without a tool which many would have regarded as critical to the operation of their businesses. From 4 February this year, the use of diquat is no longer permitted on European farms for the desiccation of potato haulms. This loss is one of the most significant challenges to face potato growers in recent years.

The magnitude of the decision by the EU not to renew the authorisation of diquat has been exasperated by the fact that there is no other readily available alternative on the market which achieves the same results.
