The 2026 growing guide for sunflowers is now available
Terres Inovia has updated its sunflower growing guide. This comprehensive guide, updated with the institute's new visual identity, will accompany growers and advisors step-by-step through the coming campaign. As in previous years, it can be downloaded free of charge from the Terres Inovia website, or ordered in printed form.
Terres Inovia a mis à jour son guide de culture consacré au tournesol. Ce support complet, actualisé avec la nouvelle identité visuelle de l’institut, accompagnera pas-à-pas les producteurs et les conseillers lors de la prochaine campagne. Comme chaque année, il est téléchargeable gratuitement sur le site internet de Terres Inovia et peut également être commandé en version imprimée.
Économe en intrants et bénéficiant d’un progrès génétique continu, le tournesol est une culture durable et compétitive, pourvoyeuse de bénéfices pour les systèmes de culture dans lesquels il est inclus. Tête de rotation à cycle court, doté d’une bonne capacité de tolérance au stress hydrique, il s’adapte à de nombreux contextes de production.
Le guide de culture tournesol de Terres Inovia permet de tout savoir sur l’itinéraire technique du tournesol : choix variétal, implantation, stratégie de lutte contre les bioagresseurs, conservation des graines, etc.
Dans cette édition 2026, Terres Inovia a actualisé l’ensemble de ses conseils et positions techniques, à l’instar des recommandations pour lutter contre le mildiou, les caractéristiques réglementaires des solutions préconisées, ou encore la liste des variétés évaluées dans le réseau Terres Inovia. Quant aux références économiques présentées, elles sont en phase avec les éléments de contexte actuel.
Le guide en version imprimée est également gratuit, seule une participation aux frais de port est demandée. Le guide de culture tournesol 2026 sera livré à partir du 23 février 2026.
