The levy body will be asking industry representatives at the biennial event to sign a pledge supporting the campaign.
"It can be as simple as passing on a recipe or displaying a poster or car sticker," said head of marketing and corporate affairs Caroline Evans.
"Alternatively you could sign up to become a Potato Ambassador, or arrange to meet your local MP. There will be plenty of resources available to help pass the messages on."
BP2013 takes place at the Yorkshire Event Centre, Harrogate, on Wednesday 27 and Thursday 28 November.
