Aardappeldemodag 2026 brought over 4,500 visitors to Westmaas amid a challenging year for the Dutch potato sector. The event focused on market pressures, extreme growing conditions, knowledge sharing, machinery and innovation.

Janine Luten, Director of the Dutch Potato Organisation (NAO), says innovation, knowledge sharing and collaboration are essential to keeping the Netherlands a global leader in potatoes while tackling labour, sustainability and regulatory challenges.

Potato Demo Day 2026 has opened visitor registration for its September event in Westmaas. The programme includes more than 120 exhibitors, 25 knowledge sessions, machinery demonstrations, a Startup Plaza and activities covering the potato value chain

Wageningen and the Dutch government are moving forward with a field trial of NTG-edited potatoes to strengthen resistance to late blight and reduce pesticide use, in a context of regulatory change in the European Union.

Aardappeldemodag has started planting activities for Aardappeldemodag 2026, with 2.5 hectares of the potato variety Libra planted last week.

Wageningen University & Research starts new field trials with genetically modified potatoes. The potatoes tested in these field trials have been genetically modified by adding or switching off multiple genes.

New trials in Europe will evaluate genetically modified potatoes with enhanced resistance to diseases such as late blight, aiming to reduce pesticide use and provide evidence for the regulatory debate on new genomic techniques.

Potato Demo Day 2026 will be held on 2 September 2026 in Westmaas, focusing on knowledge sharing, innovation, and networking. New highlights include the Startup Square and live demos, alongside key programs like the Young Farmers Program and Knowledge Barn.
