Gran Bretaña: How to stop sprouting in potato stores without CIPC
With alternative sprout control options limited or unviable in the short term, the loss of CIPC will require growers to consider a more integrated approach to long-term potato storage.
It is estimated that 80% of CIPC application in the UK is to stored potato crops and applied as a hot fog, it has provided a cheap and effective means of controlling sprouting in storage since the late 1960s.
When ingested by mammals, a metabolite of CIPC known as 3-chloroaniline (3-CA) is produced and its effect on human and animal health have driven recent regulatory risk assessments.

This has resulted in increased scrutiny due to concerns about residues reaching the food chain via treated tubers.
The European Commission recommended CIPC for non-renewal and although the active hasn’t been formally read its last rites, it is widely accepted that the active will be withdrawn imminently.
Although timelines for pesticide regulatory processes are notoriously hard to predict, it is hoped that a 12-month use-up period after any cease in sales will allow growers to use CIPC during the 2019-20 storage period.
The first crops to go into store without CIPC are likely to be those harvested in 2020.
