MIRAVIS® FAQ
Does MIRAVIS® work on more Septoria resistant varieties?
MIRAVIS® gives the best control of any level of disease and the best yields on any variety.
Optimum timing if early Septoria arises?
The key yield building leaf to protect is the flag leaf. Under threat from Septoria, maximising its lifespan will always bring the biggest yield return. A well timed T2 spray of MIRAVIS® will do exactly that. Will MIRAVIS® work well at T1? Yes, of course it will - better than anything else on Septoria. However this misses the opportunity to use it to protect the flag leaf and negates knock on benefits into Fusarium control and DON reduction.
Can MIRAVIS® control Yellow rust with the benefit of partners?
MIRAVIS® in combination with ERA® offers levels of Yellow rust control similar to that from REVYSTAR and UNIVOQ. NONE of these new chemistry products are as good on Yellow rust as ELATUS® brands. 2024 FP trials show ELATUS® brands are also considerably better on Yellow rust than VIMOY. Ideally, clear Yellow rust from the picture through T0 and T1 to allow T2 sprays to focus on Septoria. A rust active partner should always be included with MIRAVIS® where the disease remains a risk. AMISTAR® has delivered large benefits in this situation as an example. Additional triazole (tebuconazole) would also deliver similar benefits.
Does MIRAVIS® work on Brown rust?
MIRAVIS® is more active on Brown rust than Yellow rust, but the general rust control T2 guidelines laid out for it still apply. Add an active rust partner (e.g. AMISTAR®)
How does it perform when controlling other diseases?
Barley is almost a one stop shop - MIRAVIS® helps to control Ramularia, Net Blotch, Rhynchosporium, Mildew, Fusarium, and other ear diseases. Brown rust control is as good as current standards with the exception of ELATUS® brands. In Wheat, trials have shown that MIRAVIS® controls Septoria, Fusarium, Mildew and other ear diseases, Microdochium, Tan spot & Brown rust - the same as REVYSTAR/UNIVOQ. Yellow rust control is similar to REVYSTAR/UNIVOQ when combined with ERA®. Mildew control is better than other SDHI's but not at PTZ level.
Can MIRAVIS® control Microdochium and Fusarium?
Yes, MIRAVIS® helps to control both.
Does MIRAVIS® control brackling?
Good disease control = good brackling control. MIRAVIS® controls barley disease better than anything else, ensuring excellent brackling control.
Can MIRAVIS® help with DON reduction?
MIRAVIS® + PTZ more strongly control Fusarium and help with DON reduction from a T2 application, compared to PTZ alone. We see T2 use and help with Fusarium/DON control as a free bonus of its use for foliar diseases. In high risk seasons, a T3 may not be enough to guarantee mycotoxin thresholds aren't exceeded. Using APN at T2 significantly reduces that risk.
How does MIRAVIS® perform at T1 vs T2 in Barley?
In conventional barley, the flag leaf is smaller than that of wheat and it's more important to protect L2 and L3 (T1). In situations with very high Net Blotch or Rhynchosporium ahead of T1, we would recommend to apply MIRAVIS® at T1 to treat the disease pressure in front of you to protect yield. Dead leaf tissue cannot be recovered and significantly impacts yield. At T2, the ear and stem also contribute more significantly to barley yield than in wheat, and the best timing for Ramularia control is always @ GS39-45. T2 sprays also impact the Fusarium and DON production on the ear, straw and grain quality, in both wheat and barley. Overall spray at T2, IF THE MAIN DISEASE is Ramularia, or if the crop is Hybrid Barley, where the flag leaf is often larger and yield contribution is probably more like wheat. In reality, many barley crops may only receive one spray = MIRAVIS® (Reminder: MIRAVIS® can only be used once per crop).
What are the growth stages for application in Wheat and Barley?
Winter and Spring Wheat - GS30-69. Winter and Spring Barley - GS30-65.
Why are minor cereals growth stages different to Wheat and Barley?
Approvals for minor cereals are focussed on T3 and Fusarium activity initially. LEX potential for foliar diseases is under evaluation. For Oats, the earliest GS for application is GS55. Given Oat panicle emergence relative to flag leaf, this is in effect a late T2.
Is there any harvest delay?
No - green leaf area retention is extended closer to the ideal decline profile to maximise yield potential but harvest date is not affected.
How can I ensure tank mix safety?
There have been multiple trials over many seasons with no compatibility or phyto issues. Specific tank mix work up to 5 way mixes no issue. Specific PC testing no issues. Note: Syngenta only support up to 3 way mixes for any product. Download the MIRAVIS® tank mix list here.
Should I mix with other new chemistry for resistance management?
Mixtures or sequences (recent AHDB work shows both strategies are similar from a resistance management perspective) with other non SDHI new chemistry is a good resistance management strategy. For full resistance management guidelines, contact your local area manager.
Is there cross resistance to other SDHIs?
YES - MIRAVIS® is an SDHI, and in Syngenta's view ALL SDHIs are functionally cross resistant in the field. Adepidyn® is so potent however that at present it delivers outstanding control of UK Septoria.
What is the best sequence for resistance management?
MIRAVIS® should always be used with the partner product, ERA® (PTZ). We have full resistance management guidelines for MIRAVIS® covering a full range of scenario's and based on latest AHDB research and FRAG principles. For full resistance management guidelines, contact your local area manager.
What about Folpet and resistance management?
Multi-sites remain a critical part of a balanced resistance management strategy in wheat and barley. Folpet is the best option in both crops and would be classed as essential where Ramularia resistance management in particular is concerned. Syngenta has newly updated resistance management guidelines in place for cereal fungicides and MIRAVIS® based on the latest AHDB funded research.
What is the maximum number of applications?
1 application per crop.
Mobility and control in leaves not emerged?
Biokinetic studies shared show that MIRAVIS® continues to move and accumulate in newly emerging leaves long after levels of competitor AI's have peaked and are declining.
Does MIRAVIS® have malting approval?
Fully approved by BBPA.
Will MIRAVIS® damage my sprayer?
All Syngenta formulations are rigorously tested through commercial spray rigs and against different chemical compositions of sprayer components such as diaphragms and O-rings. No issues have arisen in static rig tests nor are any are expected in commercial use with MIRAVIS® formulations.
LERAP/buffer zones?
Statutory minimums only.
