Revystar fungicide



The confidence to combat Ramularia

ACVM Registration No.P009654

Mode of action: Group 3 | 7 fungicide
Active ingredient(s): 100 g/L mefentrifluconazole | 50 g/L fluxapyroxad
Formulation: Emulsifiable concentrate (EC)

Revystar® Fungicide has raised the standard for control of Ramularia in barley, provides a powerful rotation option for speckled leaf blotch in wheat, and will increase the level and spectrum of control of foliar diseases in both wheat and barley. 

“T2 is the ‘king hit’ Revystar fungicide application timing for all barley and wheat crops, with the option of an earlier spray if disease pressure is high”

Key benefits

  • Outstanding dual-active disease control for extra green leaf retention
  • The combination of Group 3 and Group 7 modes of action controls pathogens with resistance to other modes of action 
  • Superior rainfastness and tolerance of cool temperatures

How it works

Revystar fungicide is an innovative co-formulation of two extremely complementary fungicides: mefentrifluconazole, the Group 3 fungicide branded as Revysol®; and fluxapyroxad, the Group 7 active branded as Xemium®.

That robust ‘double action’ provides a combination of quick uptake and long-lasting activity. Revystar is more resilient in difficult weather than alternative options and promotes a ‘greening effect’ that can help maximise crop yields.

Crop suitability

  • Barley

    Brown rust
    Ramularia leaf and awn spot
  • Wheat

    Leaf rust
    Powdery mildew
    Speckled leaf blotch
    Stripe rust

Questions and Answers from the Field

  • Why should I start using Revystar?

    Revystar is a co-formulation, combining the latest generation Group 3 triazole fungicide with Group 7 SDHI fungicide. Its unique combination of MoA fungicides provides market-leading broad-spectrum control of key diseases in cereals, including Ramularia leaf spot in barley and Speckled leaf blotch in wheat. As we’ve learnt from the loss of Ramularia control in recent years, we can’t continue to rely solely on current solutions because shifts in sensitivity will continue reducing ef cacy and crop yields. The most sustainable approach is to incorporate new chemistry into your spray program now to protect and maintain optimal productivity.

  • Which diseases does Revystar control?

    • Barley: Ramularia leaf spot, brown rust, scald
    • Wheat: Speckled leaf blotch (Septoria tritici blotch), stripe rust, leaf rust, powdery mildew
  • What’s the best application timing for Revystar against Ramularia?

    Ramularia usually explodes at or around ear fully emerged (GS 55-59) through to medium milk (GS 75). The ‘king hit’ application timing is T2: around GS 59 for autumn crops and GS 49 for spring. T1 Revystar applications should only be used if the crop is growing slowly and Ramularia comes in early, which typically only happens in autumn crops.

  • What can Revystar be mixed with?

    Revystar can be tank-mixed with the most commonly used fungicides, like Comet®, insecticides, herbicides such as Granstar*, Starane*Xtra or Duplosan*KV and growth regulators such as Cycocel®, Moddus* Evo or Terpal®. Check the manufacturers’ recommendations for rates of any tank-mix product.

  • How will Revystar strengthen my resistance management program?

    Barley and wheat growers who are experiencing a decline in ef cacy with other fungicides can con dently apply Revystar as part of their disease management program. The new-generation Group 3 triazole in Revystar has been shown to control pathogens that have developed tolerance to fungicides with other modes of action, including strobilurins, SDHIs and even triazoles from previous generations. Do not apply Revystar more than twice per season. For resistance purposes Systiva® seed treatment counts as one SDHI fungicide application.

  • What are the withholding periods with Revystar?

    • Cereal grain & straw stubble: DO NOT harvest or graze within 42 days of last application
    • Cereal green feed/silage: allow 28 days between last application and introduction of stock for grazing or cutting for silage

    For tank-mixing, observe the longest WHP of any tank-mix partner.
