Irish growers gain access to proven wheat fungicide Univoq

Corteva Agriscience has announced that Univoq™, one of the leading fungicides used to control septoria and rusts, is now available to wheat growers in Ireland.

Univoq has been widely used across Europe and the world and consistently proven its efficacy against key diseases, most notably septoria.

The product contains the Inatreq™ active molecule in co-formulation with prothioconazle, optimised by Corteva’s patented i-Q4™ formulation which enables Univoq to stick to, spread across, and penetrate the leaf’s surface.

Its robust activity on the main diseases found in Irish wheat fields means green leaf area is maximised, laying the foundations for greater yields.

Independent trials carried out by the UK Agriculture and Horticulture Development Board (AHDB) in 2023 showed, for the third year in a row, clear daylight between Univoq’s yields and those of the next closest competitor.  

The greatest benefit of applying Univoq has been seen at the T2 fungicide timing, although many growers have also explored the benefits of the product at T1.

Liz Glynn, Corteva’s National Technical Manager for Ireland, said: “It’s really good news that Corteva is able to offer Univoq to wheat growers in Ireland this year following the great successes it has delivered in terms of disease control and yields across Europe.

“Many growers here will have already seen how effective the Inatreq molecule is having used it in our Questar™, Aquino™ and Peacoq™ fungicide co-packs which have been on the market since 2021.  

“In Univoq we now have a one-bottle solution offering simplicity and ease of use, with the additional benefit of the i-Q4 formulation.”

Steven Kildea, Plant Pathologist at Teagasc, said: “We have seen in the field that Inatreq active is an excellent molecule when it comes to controlling septoria, which is much needed.

“We’ve seen actives disappear from the Irish grower’s toolbox but Inatreq came in and has really found a home for itself in fungicide programmes. Now, with Univoq, we will see the same efficacy in terms of disease control to help build yield, but it will be co-formulated into a single bottle which will appeal to farmers here.” 

Growers have flexibility on the rates they choose to apply Univoq at, ranging between 1.5l/ha and 2l/ha depending on the disease pressure. 

Inatreq active offers outstanding biology performance, and its novel target site for septoria gives farmers an important tool to help manage the disease, as it shows no cross-resistance to existing cereal fungicide chemistries. Farmers also will benefit from its flexible application characteristics and consistent, broad-spectrum performance.
