Corteva Agriscience’s Inatreq fungicide active ingredient, offering curative and protectant control for wheat against all Septoria strains, is now approved for use in the UK in time for T2 applications.

Branded Univoq, the company says that Inatreq is the first new target site fungicide for Septoria control registered in the UK for 15 years. It gives farmers a new tool to help manage Septoria with no cross-resistance to existing cereal fungicide chemistries. The product has flexible application characteristics and consistent, broad-spectrum performance, while its patented iQ-4 formulation empowers the Univoq fungicide to stick to and spread across the leaf.

Univoq, applied as a flag leaf spray at the T2 fungicide timing, will be available in the UK in time for this year’s wheat T2 applications. Corteva says Univoq delivers an excellent length of protection, maintaining green leaf area and allowing the crop to build yield long after application. UK trials have also shown control of yellow and brown rust in line with existing market standards.

Michael Ashworth, Corteva Agriscience cereal fungicides category marketing manager, UK, says: “The major strength of Univoq is its robust control of Septoria – the number one disease threat and yield robber on UK arable farms.

“The introduction of Univoq to the UK is a major milestone for cereal growers who need innovative new chemistry to protect their crops while meeting the challenges of sustainable management and responding to farmers’ desire for innovation. The Inatreq active molecule works differently than every other cereal fungicide available to farmers in the UK. Over the past decade of development, it has demonstrated the ability to keep crops greener for longer, allowing plants to fulfil their yield potential.”

William Corrigan, Corteva’s UK & Ireland country leader adds: “This is the first new cereal fungicide from our pipeline and a clear signal of our intention to deliver the best chemistry to our customers, helping farms to deliver their goals of being profitable and sustainable for the future.

“Thanks to the natural origin of Inatreq active, we are also meeting European consumer demands for more sustainably produced food.”

Inatreq is already approved for use in cereals in France, Belgium, Luxembourg, the Republic of Ireland and Greece, and the registration process is continuing across Europe and in other key cereal growing areas.
