Potato Industry CIPC Stewardship Group announces 2015/16 product label

New statutory product label changes to Chlorpropham(CIPC) were announced in July. CIPC is an essential tool to control sproutingand is applied to around 3.5m tonnes of potatoes stored each year by around1,000 growers.

New application rates for CIPC have been agreed for2015-16. The gradual annual reduction in CIPC total dose was requested by thecompanies that hold the approvals for formulations as part of the CIPCstewardship process, and was agreed with the Expert Committee on Pesticides(previously Advisory Committee on Pesticides).

For the 2015-16 season, new statutory limits ontotal dose rates, approved by Chemicals Regulation Directorate (CRD) are30g/tonne for the fresh market and 50g/tonne for processing (including fish& chip shops and peeling). The latest time of application is 14 days beforeremoval from store for sale or processing is also a statutory requirement.

Best practice, in-line with Red Tractor FarmAssurance and the NAAC applicator group, permits just one application in coldstores (<5C), early in storage, before temperature is decreased below 7C.

From 2017 it is expected that new product labelswill permit a total dose of no more than 36 grams/tonne, says Adrian Briddon,Group Secretary of the Stewardship Group. More importantly, it is anticipated,the conditions under which this may be applied, will be more strictlycontrolled on product labels.

It is recommended that applications at full labelrates should not be carried out unless best practice methods are in place andstores are suitable for effective distribution of the chemical.    

BASIS advisors and users of CIPC should be awarethat even modest doses (around 10-14 grams/tonne) applied under conditionswhere best practice modifications have not been adopted will increase the riskof a Maximum Residue Level exceedance, added Mr Briddon.

If you use CIPC, you must check and adhere to thestatutory conditions of use and, now more than ever, it is critical that usersadopt best practice.  The easiest way of doing this is to use an NAACapplicator and ensure that a store checklist is completed before any applicationis made.  The Be CIPC Compliant campaign (www.BeCIPCcompliant.co.uk)promotes best practice and raises awareness of the issues surrounding CIPC use.The aim is to reduce the levels of residue found on crops, to safeguard itsavailability for future use.
