New data from cereal disease trials have shown that Univoq, the latest fungicide from Corteva Agriscience, has demonstrated a superior yield return when compared to Revystar XE.
Two 2022 trials – one by the Agriculture and Horticulture Development Board (AHDB), and one by Corteva, have shown that Univoq can have a financial benefit to growers of around £60 per hectare, assuming a wheat price of £250 per tonne.
According to cereal fungicide category manager Mike Ashworth, this mirrors the findings from similar trials in 2021, as well as the work carried out during the development.
“What we’re seeing is consistency across two very different years in terms of weather conditions and disease pressure,” Mr Ashworth said.
“In 2021 we had a high disease pressure year, and we know that Univoq’s major strength is septoria control, so it gave the fungicide the chance to really show what it is capable of.
“We saw a strong yield response then, and that has continued in 2022 which was an extremely hot, dry growing season for the vast majority.”
Trials were carried out at 42 sites and Univoq was found to outperform Revystar XE in terms of yield in 36 cases. Application rates were set a 1.25 litres per hectare for Univoq, against one litre for Revystar XE, said to be comparable in terms of cost to the grower.
Univoq contains the Inatreq active molecule and the patented i-Q4 formulation, and has a unique site of action, meaning there is no cross resistance.
During the 2022 season, some complaints were received from operators, relating to the failure of some parts – notably anti-drip mechanisms. Following an extensive investigation, Corteva has since issued detailed best practice advise for growers.
“There is a clear benefit to using Inatreq, both in terms of disease control and yield response, and the best practice advice we have set out will help growers get the most out of what is an extremely robust, effective product,” Mr Ashworth said.
