Regulatory requirements for 2016-17

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

Total dose Fresh market 24 grams chlorpropham per tonne of potatoes
Fresh market, store temperature 5°C or below Where storage temperature is to be 5°C or below, only a single application, up to 16 g/tonne, should be made, before the temperature is reduced below 7°C
Total dose Processing (incl. fish & chip shops, peeling) 42 grams chlorpropham per tonne of potatoes
Harvest interval The latest time of application is 14 days before removal from store for sale or processing
Equipment Equipment must be inspected and certificated annually by NSTS
Personnel Applicators must be qualified to NPTC PA1 & PA9 and should be audited by the National Association of Agricultural Contractors (NAAC)
Advisors Recommendations for CIPC must be made by BASIS qualified advisors
Stores Stores must be inspected and reported as fit for CIPC application under the Red Tractor Farm Assurance Scheme

Red Tractor Farm Assurance

Red Tractor Assurance 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.

CIPC and crops other than ware potatoes

Maximum Residue Levels (MRLs) reflect levels of pesticides expected in produce, when treated in accordance with good agricultural practice; for CIPC and ware potatoes the MRL is 10mg/kg. Where CIPC is not approved for use on particular commodities such as cereals, MRLs are set at the lowest level which can be identified in routine laboratory analysis (Limit of Determination, LOD) typically 0.01mg/kg. It is an offence to trade commodities with a residue content above the MRL. See https://secure.pesticides.gov.uk/MRLs/search.asp

Treatment of potatoes with CIPC results in contamination of the building and boxes. Contamination is long-lived, and this presents a risk of an exceedance of the MRL, if crops other than ware potatoes are stored in them. Red Tractor Farm Assurance requires a risk assessment for CIPC to be carried out for buildings before these are used. See http://www.assuredfood.co.uk/resources/000/965/978/CROPS_Online.pdf

Buildings in which CIPC applications have taken place must be identified. Click here for an example of such signage.
