New Guide for Potato Store Owners
The Potato Industry CIPC Stewardship Group in the UK recently published a new factsheet entitled “CIPC Application: A store owner’s guide. Essential information for making potato stores CIPC compliant from the 2017/18 season.”
New controls planned by CIPC approval holders, and backed by Industry Stewardship, will mean all CIPC applications from the 2017 harvest are made using ‘active recirculation’ to optimize efficacy at the new pan European lower maximum total dose (36g/t), enhance distribution and reduce the risk of Maximum Residue Level (MRL) exceedance.
‘Active recirculation’ is the new industry agreed term to describe the recirculation of air (containing CIPC fog) by fans, according to the report. Research conducted by AHDB and others within the industry has shown that the correct use of fans can significantly improve the uniformity of CIPC distribution, reducing the risk of maximum residue level exceedance. In most cases, this can best be achieved using variable speed control to slow fans down to provide a steady circulation of fog throughout the store. The new publication by the Stewardship Group provide practical, illustrated guidelines that store owners can follow to get their facilities compliant.
The factsheet covers topics as positive ventilation, open suction, plenums, bulk storage, Be CIPC Compliant.

Positive ventilation is the best way of achieving ‘active recirculation’. It has provided the best results in trials in achieving the most uniform distribution of CIPC in box stores, according to the guideline.
The guideline mention that it is important to understand that positive ventilation imposes a resistance (back pressure) to flow and therefore there has to be a sufficient pressure generated within the ‘active recirculation’ system to overcome this resistance, otherwise uniform distribution will not be achieved.
