Make sure you are ready for the future with CIPC
CIPC labels and Stewardship guidance updated for 2016/17.
hanges for the forthcoming
year to product labels for
chlorpropham (CIPC) have
recently come into force and,
on 1 August, the Potato
Industry CIPC Stewardship
Group released its updated guidance for the
forthcoming season.
CIPC is an essential for the control sprouting
and is applied to almost 2 million tonnes of
potatoes stored each year across the industry
in Great Britain.
In line with the ‘Step Down’ process working
towards a new pan-European rate for 2017,
there are new, lower application rates for CIPC
use in the coming season which have now
been approved. These were requested by the
companies that hold the approvals for
formulations as part of the CIPC Stewardship
process and will help to ensure compliance
with the Maximum Residue Level (MRL) of 10
mg/kg.
For the 2016-17 season, the new statutory
limits for total dose, approved by Chemicals
Regulation Directorate (CRD) are 42
grams/tonne for processing (including fish &
chip shop supplies and peeling) and 24 g/t for
the fresh market. The latest time of application
is 14 days before removal from store for sale or
processing and is also a statutory requirement.

There are new, lower application rates for
CIPC use in the coming season which have
now been approved
Additionally, Stewardship best practice,
endorsed by the NAAC’s CIPC Applicator
Group and Red Tractor Farm Assurance,
continues to allow just one application of up to
16 g/t in cold stores as CIPC residue declines
more slowly at cold temperature. This applies
to all stores to be held below 5°C. This
application should be made early in storage
during pull-down, before the temperature is
decreased below 7°C, for maximum efficacy.
Be 2017 Ready
The Stewardship Group is also urging users
to ‘Be 2017 Ready’ by taking on board the
changes necessary to introduce Active
Recirculation as part of the application process.
This requires that the fog must be actively and
evenly recirculated through the potatoes using
the main or supplementary fans and will be
manadatory in all stores from July 2017
onwards.
It is recommended that users consult their
NAAC CIPC Applicator to discuss this
requirement now to ensure that, if steps have
not yet been taken, applications can still be
made next season.
Here is the definition for Active Recirculation
and associated guidance released by PICSG:
Active Recirculation – for application of
Chlorpropham (CIPC) to stored potatoes
The active, even movement and recirculation
of airflow, through stored potatoes, during and
after Chlorpropham application (until the fog
has cleared) accomplished via any suitable
mechanical means in order to improve
application uniformity and maximize product
efficacy.
