BRUSSELS — The European Union’s agriculture commissioner said Wednesday that he planned to double the amount of money available for promoting the sale of farm goods, in an effort to counteract the effects of a boycott by Russia, an important export market for European producers.

Dacian Ciolos, the European commissioner for agriculture and rural development, said the plan could make a total of 120 million euros, or roughly $157 million, in public funds available for marketing — €60 million from Brussels, up from €30 million, and another €60 million from national farming organizations that are obliged to match European funding for such promotion.

“I strongly encourage agricultural organizations to make the most of this opportunity and to present ambitious promotion schemes in the coming weeks,” Mr. Ciolos said, adding that the goal was to “facilitate trying to find new destinations, new outlets, new markets for our products.”

The Russian government announced its boycott in August after Europe imposed sanctions on Russia for its annexation of Crimea and the destabilization of eastern Ukraine. The Russian action was aimed at broad swathes of the European dairy, meat, fruit and vegetable sectors.
