Questions and Answers

  • Who does the CIPC Stewardship Group represent?

    It represents the potato supply industry, the CIPC approval holders and also has representation from independent organisations from industry and academia.

  • Will further restrictions on the use of CIPC be imposed?

    We don’t know. CIPC is currently being monitored by the Expert Committee on Pesticides and re-reviewed in the EU (EFSA). Either of these could result in additional restrictions.

  • What further research is being conducted?

    AHDB has a commitment to further work to improve the use of CIPC. See http://potatoes.ahdb.org.uk/publications/114r483-cipc-commercial-stores

  • How can I source additional information?

    In the first instance, call Sutton Bridge CSR on 0800 02 82 111

  • Is there research to investigate new alternatives to CIPC?

    Yes. AHDB has projects on alternatives (see http://potatoes.ahdb.org.uk/publications/r464-ethylene-processing for example) and some industry parties are doing their own trials.

  • What will happen if further residue exceedances are detected?

    It is likely that tighter restrictions will be imposed although there is always the possibility of revocation.

  • How is the CIPC Stewardship activity and research funded?

    There is joint funding from industry but the majority of the operational support for stewardship comes from AHDB Potatoes levy.

  • What is the timescale for the stewardship group to demonstrate results?  

    The Action Plan implemented by the Potato Industry CIPC Stewardship Group had a 5 year initial timeframe. The Expert Committee on Pesticides reviewed progress in 2013 and continues to be very supportive of PICSG activities.

  • What is CIPC?

    Chloropropham or Iso-propyl chlorophenyl carbamate

  • How widespread is the use of CIPC?

    Pesticide Usage Surveys (published by FERA) show about half of GB stored potatoes are treated with CIPC.

  • What actions have the Stewardship Group agreed to undertake?

    A range of measures, but principally united industry action has included communication of best practice, support for R&D, introduction of additional controls, plus monitoring and auditing.

  • What level of uptake has there been of CIPC stewardship measures?

    In a 2015 survey (BP2015, Harrogate, November 2015) 69% of those surveyed were '2017 compliant'. We need everyone else to follow. Be CIPC Compliant! 

Farmers & Store Managers

  • What is the Maximum Total Dose for CIPC?

    For fresh market: 24 grams/tonne
    For processing: 42 grams/tonne

  • How do I find an approved CIPC fogging contractor?

    Click here for a list of approved contractors.

  • What alternatives to CIPC are currently available?

    Click here for information about alternatives.

  • What can be done in box stores?

    Click here for best practice information.

  • Who is ultimately / legally responsible for the amount of CIPC applied to a crop?

    The owner is responsible for the crop and any chemical applications made to it.

  • At what point should the first application of CIPC be applied?

    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.

  • How can the need for repeat CIPC applications be assessed?

    Reapplication of CIPC should take place when fresh growth is detected. Note re-application is no longer recommended in stores with a holding temperature below 5°C.

  • What harvest interval restrictions are in place for CIPC products?

    The harvest interval for CIPC products varies. For hot-fog applied CIPC it is usually 14 days, but you must consult the product label.

  • Can stores be retro-fitted to comply with stewardship measures?

    Yes. This is straightforward in bulk stores and usually more costly in box stores. Or call SBCSR on 0800 02 82 111 for the best solution.

  • Are there any effective alternatives to CIPC that do not impact fry quality?

    There are currently no alternatives that can easily and viably take the place of CIPC in stores used for crops for processing. Therefore we need to use it carefully.

  • Do I have to use a fogging contractor to apply CIPC?

    No. You may apply CIPC yourself but you must be appropriately qualified and only use machinery that has passed the annual NSTS test. To supply some markets, you must also be signed up to relevant schemes eg NAAC CIPC Applicators’ Group.

  • Are there any events taking place that I can attend?

    AHDB has a full schedule of Knowledge Exchange events, see http://potatoes.ahdb.org.uk/events or call SBCSR on 0800 02 82 111 for specific questions.

  • Is it possible to guard against CIPC hotspots developing in the store?

    Yes, adopt and follow best practice.

  • Are there potato varieties more resilient against sprouting?

    Sprouting is necessary for potatoes to complete their life cycle, but dormancy varies considerably from variety to variety. Long dormant varieties can be used to modify CIPC requirement.

  • What CIPC products are available?

    Details of approved CIPC products are available from the Chemicals Regulation Directorate. Follow the link to see what products are available.

  • What information / guidance is available in relation to CIPC application?

    In addition to AHDB research, information on CIPC application is available from the NAAC CIPC Applicators’ Group and CIPC Approval Holders or call SBCSR for specific questions.

  • What qualifications are required to recommend the use of CIPC?

    All advisors on plant protection products, since March 2013, must be BASIS qualified. The only exceptions are those working temporarily under the direct supervision of a BASIS qualified advisor.

  • What training is available?

    Recommendations for pesticide applications should be made by a BASIS qualified advisor. BASIS (Stored Potatoes) is available for CIPC and other pesticides used in potato stores. See the BASIS website http://www.basis-reg.com/default.aspx

  • What measures can be taken to minimise the need for CIPC?

    Consider the use of an alternative sprout suppressant as well as, or instead of, CIPC. It can also be minimised by selecting varieties with long dormancy. For processing, selection of varieties with low temperature tolerance (allowing a lower storage temperature without darkening fry colour) should also reduce the need for CIPC treatment in storage.

  • Can potato stores treated with CIPC subsequently be used for other crops?

    No. There is no approval for the use of CIPC on commodities other than potato and there is a real risk of contamination. Cereals, oilseeds and vegetables with CIPC above the limit of detection are illegal and may not be traded.  

    See the Red Tractor website for more information at assurance.redtractor.org.uk

  • What building checks should be conducted prior to CIPC application?

    As part of the Red Tractor Farm Assurance protocol all buildings should be assessed as being suitable for CIPC use, before application. Use the store checklist downloadable from this website.

 

 

Agronomists

  • Do agronomists have a role to play in CIPC?

    Yes. Variety choice has an important influence on CIPC requirement. Varieties with a short dormant period and those with a requirement for a relatively warm storage temperature, to maintain quality, increase the need for CIPC treatment in storage.

  • What qualifications are required to recommend the use of CIPC?

    All advisors on plant protection products, since March 2013, must be BASIS qualified. The only exceptions are those working temporarily under the direct supervision of a BASIS qualified advisor.

  • What training is available?

    BASIS (Stored Potatoes) is available for CIPC and other pesticides used in potato stores. Appropriately qualified agronomists may then make recommendations for CIPC treatment following crop inspections in store. See the BASIS website http://www.basis-reg.com/default.aspx

 

Packers & Processors

  •  How can merchants and retailers influence the use of CIPC?

    By requiring all their suppliers to comply with CIPC best practice so we can ensure compliance and avoid  Maximum Residue Levels being exceeded.

  • What alternatives to CIPC are currently available?

    Click here for information about alternatives.

  • Are there any effective alternatives to CIPC that do not impact fry quality?

    There are currently no alternatives that can easily take the place of CIPC in stores used for crops for processing. Therefore we need to use it carefully.

  • How necessary is the use of CIPC in stored potatoes?

    The availability of CIPC is critical for sprout suppression during storage of potatoes in Great Britain.

  • Is there research to investigate new effective alternatives to CIPC?

  • Can retailers / the market impose their own restrictions on the use of CIPC?

    Yes, retailers may impose additional restrictions on the use of pesticides in addition to the statutory controls.

  • What does Red Tractor Assurance criteria require?

    In addition to the statutory conditions,

    • The use of a non-BASIS advisor is a critical failure point.
    • Application equipment must be inspected and certified annually.
    • Stores where CIPC is used must be inspected, and declared suitable, prior to applications taking place.
  • What is the MRL and how is it determined?

    MRL stands for Maximum Residue Level. This is the maximum concentration of CIPC that may occur on potatoes being traded. It is not a measure of ‘safety’ but is used to indicate that the product label has been complied with. The residue level is determined by an approved analytical laboratory. Click here for instructions for taking a sample for residue testing.

  • Are processed or fresh potatoes at greatest risk of exceeding the MRL (Maximum Residue Level)?

    Most recent exceedances of the MRL have been in fresh potatoes but all potatoes are at risk if best practice is not followed. We cannot be complacent in any sector.

 

Contractors

  • What are the maximum dose rates for CIPC?

    For fresh market: 24 grams/tonne
    For processing: 42 grams/tonne

  • How do I become an approved CIPC contractor?

    Details on becoming an NAAC approved contractor can be found here.

  • Who is ultimately/legally responsible for the CIPC applied to a crop?

    The owner is responsible for the crop and any chemical applications made to it.

  • At what point should the first application of CIPC be applied? 

    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.

  • How can the need for repeat CIPC applications be assessed?

    Re-application of CIPC should take place when fresh growth is detected. Note re-application is no longer recommended in stores with a holding temperature below 5C.

  • What responsibility does the contractor undertake with applications of CIPC?

    The contractor is responsible for the safe application of each CIPC treatment, according to the product label. The contractor is not responsible for management of the crop, although may – if appropriately qualified – be able to make a BASIS recommendation for treatment.

  • Is it possible to guard against CIPC hotspots developing in the store?

    Yes, by using fans for low-speed recirculation of CIPC fog through bulk piles. Changes to storage ventilation equipment may be needed as recirculation must usually be carried out with fans operating at lower speeds than normally used for ventilation.

  • What CIPC products are available?

    Details of approved CIPC products are shown on the Chemicals Regulation Directorate website.

  • What controls are in place governing equipment used in CIPC application?

    Fog application equipment must be inspected every year.
