The Potato Industry CIPC Stewardship Group (PICSG) has warned potato growers and buyers against applying sprout suppressant Chlorpropham (CIPC) at 2020 store loading.
The popular active, previously used on over 90% of the 3.5 million tonnes of potatoes stored in Britain, had its approval for use withdrawn by the European Commission on January 8.
The maximum ‘use-up’ period of nine months was set by the EU, with member states able to set their own date within that timeframe.
This means the last possible use-up date is October 8 – during the very early stages of potato store loading in a typical season. This date has now been officially confirmed as the use-up date in the UK.
PICSG chairman Dr. Mike Storey said that businesses who have not been monitoring technical messages will be at risk of crops not passing inspection.
“This will become an issue at the point at which the Maximum Residue Level of CIPC allowable on potatoes for human consumption, which is currently 10 parts/million, drops to a new temporary Maximum Residue Level. We think this will happen before the 2020 harvest comes out of store.
“We know where we hope it will be, and it is at a level that will be achievable if you’re using stores that have previously used CIPC, as long as cleaning guidelines are followed – but if you apply CIPC to crop this year it will not pass an inspection.”
Some countries, including potato superpower Belgium, have taken this possibility out of the equation by bringing the use-up period forward to June.
‘If you fog them, you can’t flog them’
Adrian Cunnington, head of Crop Storage Research at AHDB, believes many growers are aware of the changes and will know that the 2019 harvest is the last that can be treated with CIPC.
“Most growers are on top of this situation, but we are still receiving some worrying reports that there are producers who are not fully aware of the changes and their consequences,” he said.
Information on alternative products is available on the AHDB website’s storage hub. And, to help store managers prepare, AHDB is offering free one-to-one potato store visits via its new Storage Network. The visits are designed to help businesses prepare for life after CIPC.
The Storage Network is delivered by Sutton Bridge Crop Storage Research and a group of independent advisors trained by our specialists at SBCSR. Alongside eight additional storage research projects, it is part of an £800,000 ring-fenced fund to help the industry deal with the withdrawal of CIPC, announced by AHDB in 2019.
Store managers can sign-up for their visit via the AHDB storage hub or by calling: 01406-359-419.
