Potato growers in the UK using sprout suppressant chlorpropham (CIPC) will need to thoroughly clean stores after the 2019 crop is unloaded next summer to lower the risk of residue exceedances after the active is withdrawn.
Plant growth regulator CIPC is the potato industry’s go-to method of controlling sprouting in store and has been in commercial use since the 1960s.
The European Commission’s Standing Committee on Plants, Animals, Food and Feed (SCoPAFF) first recommended CIPC’s approval for non-renewal February in 2019 and after some wrangling between EU Member States, the non-renewal regulation came into force on 8 July.
On 15 December, the Chemicals Regulations Directorate (CRD) finally published the timeframe for its grace period in the UK. Potato growers will be able to buy CIPC products until 8 January 2020 nd can legally use them in potato stores up to 8 October 2020.
