Be CIPC Compliant: 2014/15 update
The spotlight remains on CIPC just now following the reporting in June by the Defra Expert Committee on Pesticides Residues in Food (PRiF) of a further MRL exceedance in a potato sample taken from a box store supplying to the chip shop market. This is disappointing but highlights the need for continued vigilance in the use of CIPC and adherence to Stewardship and best practice recommendations.
The Approval Holders  have just announced the rates of use for 2014/15 and this will see a reduction in the overall limits for the forthcoming season to 30 grams/tonne for fresh market and 58 g/t for processing. The maximum single dose has been cut to 18 grams/tonne and the minimum interval between treatment and sale has been extended to 14 days.
The limit of one treatment on all crops being held in cold stores (ie at temperatures of 5°C and below) will continue in the light of further evidence of slow residue decline under these conditions. 
All previous approvals have been superseded by these changes so old CIPC stock must be used in accordance with the new guidance.
Red Tractor Farm Assurance also requires the following steps to be followed:
  • All recommendations to be made by a BASIS-qualified advisor*
  • All application equipment to be NSTS tested, in date and used by a member of the NAAC CIPC Applicators’ Group
  • A PICSG Store Checklist to be completed by the store owner prior to any CIPC application
  • All stores to be labelled where CIPC has been used (to avoid cross contamination of crops for which CIPC is not approved, eg wheat)
  • The use of ventilation for distribution of CIPC is recommended and will become a requirement of RTFA for bulk stores in 2015/16.
*The next course for BASIS Post-Harvest accreditation is being held at SBCSR on 27/28 August 2014 (exam on 2 September). For details, see

StoreCheck already in demand!
The new StoreCheck auditing service, being carried out by Sutton Bridge CSR in conjunction with Farm Energy, has got off to a good start and the team have been out and about around the country undertaking assessments during the close season.
Key features of the service include store leakage measurement and energy usage advice. StoreCheck offers an opportunity for the performance criteria for individual stores to be assessed. This is quite simply influenced by any factor which changes the store condition from its optimum. There are some things the store operator cannot influence, such as crop respiration, which generates heat and so the store has to be cooled. But there are factors we can influence, such as air leakage into the building. On a breezy day, warm air leaks into a store and this can increase running costs by as much as 50%. It also increases risk of condensation which will encourage disease development. 
Ventilation performance can also be seriously compromised by poor air circulation which means heat can’t be extracted as effectively as it should be, increasing both electricity costs and crop weight loss. Any limitations on heat removal reduces efficiency and so it takes longer (and costs more) to change the store condition. Contact us now to book an audit for your store - the small investment needed for a StoreCheck assessment could be paid back in as little as one season. Call 01406 359419 to make a booking (please be prepared to give the store’s dimensions) or, for more information, see our video at
