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