Early CIPC applications critical

As crops come into store, potato growers are being urged to prepare for short dormancy break periods, due to the warmer, brighter conditions during the growing season. It’s adding to the imperative to apply sprout suppressant chlorpropham (CIPC) as early as possible, advise Potato Council.


Adrian Briddon urges growers and contractors to apply CIPC as early as feasible

Potato Council technologist and member of the Potato Industry CIPC Stewardship Group (PICSG), Adrian Briddon, reminds growers that the ‘Be CIPC Compliant’ initiative, launched last month, urges growers and contractors to apply CIPC as early as feasible, once crops have gone into store. “This strategy improves product efficacy and, where applicable, extends the interval period between applications,” he says.

He adds that the 2013 season is compounding the issue, with potato sprouting likely to occur earlier than normal. “As a consequence, the timing of applications of the sprout suppressant ‘CIPC’ will be crucial. There is no reason to delay.”

CIPC application

There are no prescriptive time periods for CIPC applications, however Adrian stresses that it is important that crop owners view CIPC as a product that is applied as a preventative rather than a curative measure to comply with stewardship objectives. “As soon as the crop is dried and cured, CIPC should be applied,” he advises.

“It’s therefore important to plan ahead and contact contractors before the crop is harvested so they’re lined up well in advance.” He adds that it is vitally important that crop owners comply with stewardship guidelines to ‘Be CIPC Compliant’ and prevent further exceedences of the CIPC maximum residue levels, in order to retain the sprout suppressant, which the industry relies upon so heavily.”

There are many factors affecting CIPC distribution in the store and crop owners are also advised to assess the store environment and infrastructure to optimise CIPC distribution. More information and further best practice guidelines are available at the new Be CIPC Complaint website:
