On 1 September 2020, Euralis Semences and Caussade Semences merged to create Lidea, an international seed company. Lidea inherits more than 80 years of expertise and experience and is thus equipped to become the best multi-crop seed partner for farmers seeking to improve their performance.

Lidea history

Lidea has been firmly rooted in the South-West of France since 1936, and benefits from a strong European network of 16 subsidiaries spreading from the Atlantic to the Urals. All our sales teams are deployed on the European continent as close as possible to our customers and markets to ensure proximity and develop trust. An international development team builds partnerships beyond the European continent. Today, Lidea varieties can be found across all 5 continents and are sold in 48 countries.

Lidea inherits agronomic and industrial expertise gained from a strong Research and Development network established throughout Europe, to innovate in the production of very high-quality seeds capable of responding precisely and appropriately to all growing conditions.
