Revystar® XE: Everything you need at T1
Despite record-breaking rainfall across several counties this winter, a kind autumn gave winter wheat a strong start. As a result, there is plenty of yield potential to be protected.
Proven over the last six years, Revystar® XE is trusted to deliver value and broad spectrum disease control of septoria, yellow rust, brown rust control and eyespot activity*, as well as protecting higher-resistance risk actives for the years ahead.
Revystar® XE can answer this year’s tough T1 questions like:
- How to deal with disease uncertainty? Current conditions favour septoria development, yet the breakdown of the YR15 resistance gene and the carryover inoculum from 2025 means yellow rust is a real threat. Recent reports suggest brown rust is present too. Revystar® XE is the proven all-rounder.
- How to best manage resistance? AHDB funded work conducted by Niab in 2025 showed that applications of either Iblon® or Adepidyn® can select for insensitive septoria isolates, this resulted in advice, cautioning using both Iblon® and Adepidyn® within a programme. The findings emphasise the need to incorporate diversity and to tread carefully when choosing products this season. Revysol® adds invaluable diversity to programmes. It is the only triazole in the market with effective septoria control and protects higher-resistance risk active ingredients.
- How to deliver return on investment? After three challenging years, crop and input prices continue to be challenging. Every penny spent is under close scrutiny. Across independent comparisons (below) and BASF trials**, Revystar® XE delivered a +£51/ha margin benefit over Ascra® Xpro, following a 0.26 t/ha yield uplift.

With these questions in mind, we catch up with independent agronomists and uncover their priorities for the season ahead.
Forward crops at higher disease risk
“In January we had100-150mm of rain – it is a lot for Kent. Fortunately, most of the winter wheathas good root structures. They’ve tillered well too, so overall, establishmenthas been good,” says Simon Roberts of CCC Agronomy.
“We are grazing winter wheat crops with sheep wherewe can. It’s about managing them backwards rather than trying to push them on,”adds Chris Taylor of Down To Earth Agronomy based in South Wales, Herefordshireand Gloucestershire.
After so many challenging autumns, BASF Business Development Manager, Jared Bonner, says it is a relief that so many crops are heading into the spring with yield potential intact.
“The downside of takingadvantage of a kind autumn and drilling early is that it gives septoria andyellow rust more time to build up. Unfortunately, we’re heading into the 2026 seasonwith higher potential for disease development.”
Chris agrees, adding: “With the amount of rainfall we’ve had, it is setting up to be a high septoria year. There are forward, lush crops around too.
“I’m also conscious of how the breakdown of YR15 will affect some of the varieties that are in the ground and the potential of yellow rust to gather pace.”
Changes in resistance scores are also at the forefront of Simon’s mind: “Given the varieties and the fact I’ve seen rust inoculum in some Crusoe already, rust will definitely be a focus of the T0s. If we have high pressure at that time, T0s will be tebuconazole-based but if not, it’ll be centred around strobilurins.”
“We are starting to get anumber of reports of brown rust,” agrees Jared. “It’s a disease worthwhileconsidering when building programmes. In 2024, brown rust made an early entryand some had subsequent issues controlling it.”
“Eyespot is also worth keepingan eye out for. Currently, conditions are right for all key diseases makingRevystar the correct choice for T1,” he says.
Revystar® XE: the all-rounder that protects other chemistry
Chris has used a lot of Revysol® over the last couple of years and notes its role as a solid all-rounder which is particularly useful at T1.
For Jared, this is one of Revystar® XE’s key strengths.
“At T1, we need to cover all the bases, especially if current conditions persist.
“Revystar meets this brief. The AHDB fungicide performance curves highlighted the stability of Revysol, showing its consistent strength against septoria and rusts. Across 12 septoria trials between 2023 and 2025, at 50% full rate, Revysol (Myresa) delivered a 0.2t/ha yield increase over Vimoy (Iblon). While across three yellow rust trials it delivered a 0.1t/ha yield uplift (at 50%) compared to the new SDHI.
“In Revystar, Xemium complements Revysol’s rust control and adds eyespot activity, whilst being protected by the strength of the unique azole.”
Revysol® is the only isopropanol triazole in the market. The molecule has a flexible hook which assumes different positions, allowing it to bind with fungal pathogen’s target enzyme, even in shifted strains.
“Newer actives - like Iblon in Vimoy, Adepidyn in Miravis and Inatreq in Univoq - are primarily being mixed with prothioconazole. In these cases, it is the clearly the newer chemistry – the SDHIs and QiIs - that is doing the ‘heavy lifting’ as far as controlling septoria and they are given little protection from the prothioconazole element.
“Revystar is different. It is the azole that does the heavy lifting. By including Revystar at T1, you’re alleviating the selection pressure and protecting other products in your programme.”
Choose Revystar® XE at T1 for:
- Protective and curative activity
- Great all-round protection
- Protection of other higher resistance risk actives
- Yield uplifts and a return on investment (or excellent value)
