Future of CIPC key topic at AHDB Potatoes Storage Day

27 November 2012

CIPC will be a key topic at the forthcoming AHDB Potatoes Storage Day to be held at Sutton Bridge Crop Storage Research (SBCSR), near King’s Lynn, on 29th November.

It will be an opportunity to find out the facts and best practice measures that can be taken to give CIPC a viable future in GB potato production, and follows concerns raised at the highest regulatory levels relating to residues of the sprout suppressant chlorpropham (CIPC) being detected in exceedance of the Maximum Residue Levels (MRL).

“These exceedances could result in the withdrawal of CIPC,” warns Mike Storey, Head of R&D at the AHDB Potatoes. “The loss of CIPC would have serious implications for the potato industry, for many businesses there are no alternatives.”

The Storage Day event will be interactive, with both fresh and processing sector experts on hand to answer questions in a 'Question Time' style forum where the future of CIPC will be debated along with other industry challenges.

“It’s a ‘must attend’ event for potato and field vegetable producers, store managers, advisors, agronomists, purchasers and retailers,” says Mike.

Practical changes will also be presented, with Adrian Cunnington, the Head of SBCSR, detailing how structural and management changes to potato stores can improve CIPC efficacy.

“Store design, crop condition and climatic factors at the time of application are crucial to achieving the correct airflow, distribution and efficiency of CIPC,” comments Adrian.

“Applications need to be planned carefully so that maximum total dose rates; 36 grammes of CIPC per tonne of treated crop on potatoes destined for the fresh market, and 63.75 g/tonne for processed potatoes – are not exceeded.

“If good practice is not followed, in terms of both store management and application, the MRL can be exceeded,” adds Adrian.

Mike Storey advises that the industry needs to demonstrate it can ensure CIPC exceedances will not continue to occur. “However, if the industry fails to resolve concerns, then the official body concerned – the Advisory Committee on Pesticides – will have no choice but to recommend regulatory action to Minsters.”
