CIPC: GET IT ON EARLY

013/14 How to Be CIPC Compliant Be CIPC Compliant is a new initiative from the industryled CIPC Stewardship Group. CIPC (chlorpropham) is vital to the potato industry, with some 1. million tonnes of stored crop receiving the treatment there are no viable alternative sprout suppressants currently registered. Exceedance of the maximum residue level (10mg/kg) resulted in the use of CIPC being referred to the Advisory Committee on Pesticides and the setting up of the Potato Industry CIPC Stewardship Group (PICSG). Be CIPC Compliant takes forward the Group s drive to ensure that the issues surrounding the use of valued CIPC sprout suppressants in potato stores are addressed by the entire potato industry and is responsible for the development and delivery of a Stewardship Action Plan to maintain the availability of CIPC for our industry and ensure best practice. It is important that full adherence to the Code of Best Practice is achieved and that Best Practice guidelines for the use of CIPC are fully met in order to comply with Red Tractor Assurance, which, with new criteria, requires the auditing of all stores where CIPC is used. This demands that crop owners demonstrate that a check has been carried out to ensure stores are suitable for CIPC use before any application is carried out. This check will focus on key aspects of the store which affect the distribution and performance of the sprout suppressant, from store location and structural integrity, through to relative volume of crop and uniformity of temperature control. To Be CIPC Compliant means to proactively respond to the serious issues surrounding the use of the potato sprout suppressant CIPC and to follow the guidance set out by this initiative from the Potato Industry CIPC Stewardship Group. Every part of the potato supply chain has an interest in preserving a future for this important crop protection tool. CIPC is widely depended upon by the industry, as there are currently no alternatives for many businesses supplying UK fresh and processed potatoes. Unless the industry can demonstrate that Maximum Residue Level (MRL) exceedances of CIPC on potatoes will not occur, then it is likely further regulatory action will be taken, which could result in a loss of the product. Key requirements Total dose Equipment Personnel Advisors Stores Fresh market: 36 grams/tonne Processing (incl. fish and chip shops) 63.75 grams/tonne Equipment must be inspected and certificated annually by NSTS Applicators must adhere to the CIPC Code of Best Practice, be qualified to NPTC PA1, PA9 and should be affiliated to the National Association of Agricultural Contractors (NAAC) Recommendations for CIPC must be made by BASIS qualified advisors Stores must be inspected and pass a stewardship store check to comply with the Red Tractor Farm Assurance Scheme. This check should be repeated for each CIPC application Responsibility Overall responsibility for CIPC use lies with the crop owner not the store manager or the CIPC applicator Agriculture and Horticulture Development Board 013.

How to Be CIPC Compliant Follow Best Practice Guidelines At store loading, remove as much soil as possible and ensure the crop is dry and cured. Avoid holding varieties with contrasting dormancies in the same store and do not overestimate the time taken for curing The first application must be made prior to dormancy break, don t delay initial application if crop is warm or harvest is suspended before the store is full Minimise sprouting pressure and CIPC requirement: Pull down as quickly as possible and hold at the lowest temperature that crop condition and enduse permit Recirculate store air continuously for a minimum of 6 hours to ensure temperatures are as even as possible prior to application. In stores with refrigeration, do this by turning off the fridge but leave the fans on. Be sure not to introduce warm ambient air that may cause condensation on cold potatoes, concrete floors or metal ductwork, etc Where fans are used during applications, fridge coils should be bypassed Avoid making applications under windy conditions New developments Chlorpropham (CIPC) will be reviewed by the Advisory Committee on Pesticides in late 013. Significant changes to the way CIPC can be used are anticipated. To help prevent exceedances of the maximum residue level, all CIPC formulations will carry additional instructions for 01314 Approval holders strongly recommend initial applications to be made within 3 weeks of store loading and the use of positive ventilation for recirculation of fog during applications. In low temperature stores (where holding temperature will be below 5 C), only a single application should be carried out during temperature pulldown and before the temperature is reduced below 7 C CIPC Stewardship Store Checklists must be completed before applications and this becomes a Critical Failure Point in the Red Tractor Farm Assurance scheme in 01314 10 Agriculture and Horticulture Development Board 013.

013/14 How to Be CIPC Compliant Crop owners 1. Take responsibility for your crop, your stores and those applying CIPC and advising on its use on your behalf Understand that the crop owner is responsible for CIPC use (and all other treatments) and conformance with the MRL Ensure store inspections happen as required by the Red Tractor Farm Assurance scheme Ensure all CIPC recommendations are taken from a BASIS qualified advisor and are recorded Ensure applicators are qualified to National Proficiency Test Council PA1 and PA9 level, are members of the National Association of Agricultural Contractors CIPC Applicators Group and that all equipment used has been tested under the National Sprayer Testing Scheme. Get it on early Apply the first treatment within 3 weeks after harvest (or at the earliest occasion thereafter) even in the absence of signs of breaking dormancy Use low speed fan assistance in all bulk stores and in box stores with positive ventilation to aid distribution. Fit inverters to those stores that don t yet have this capability For overhead throw box stores and when applying to varieties prone to skin spot, seek best practice advice from Potato Council at Sutton Bridge Crop Storage Research on 0800 0 8 111 Agriculture and Horticulture Development Board 013.

How to Be CIPC Compliant 3. Get it on once (cold stores) In cold stores with a holding temperature of 5 C or below, use just one application of CIPC, ensuring the treatment is applied before the temperature is reduced below 7 C. Recirculate air for at least 6 hours, without cooling, prior to application to ensure temperatures are even at the time of treatment 4. Use the tools to make sure you comply Always adhere to the Stewardship Code of Best Practice for Application of CIPC and the Best Practice Guidelines for the use of CIPC. Access both easily at www.cipccompliant.co.uk Use a Store Checklist and comply with the requirements of Red Tractor Farm Assurance CIPC applicators Only apply CIPC if you hold NPTC PA1 and PA9 qualifications and you are audited by the NAAC Ensure all applications have been recommended by a BASIS qualified advisor Ensure all equipment has been NSTS tested and is in date Always follow the CIPC Code of Best Practice Only apply CIPC if a store passes the CIPC Store Checklist and complies with the CIPC Code of Best Practice Potato supply chains Ensure treated potatoes are only sourced from stores following the CIPC Code of Best Practice More information is available from: Potato Industry CIPC Stewardship Group, Sutton Bridge Crop Storage Research, East Bank, Sutton Bridge, Spalding, Lincolnshire PE1 9YD Tel: 01406 351444 Email: enquiry@cipccompliant.co.uk www.cipccompliant.co.uk 1 Agriculture and Horticulture Development Board 013.
