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.

• What can I spray for powdery mildew?

  BASF’s Revystar Fungicide is an excellent choice for controlling powdery mildew in wheat. Its powerful combination combining the latest generation Group 3 triazole fungicide with Group 7 SDHI fungicide not only combats powdery mildew, but also provides broad-spectrum control for a variety of key diseases in cereal.

• How do you get rid of leaf rust?

• Does wheat need fungicide?

  Wheat crops can benefit from fungicides like BASF’s Revystar to safeguard against diseases such as speckled leaf blotch, stripe rust, leaf rust, and powdery mildew. Revystar’s unique formulation ensures extended protection and healthier wheat crops.

• How do you control stripe rust of wheat?

  Stripe rust in wheat can be managed effectively with BASF’s Revystar fFungicide. This product's double-action formulation ensures quick uptake and long-lasting control, providing a resilient solution against stripe rust.

• How much yield does barley scald lose?

  Scald of barley can cause significant yield loss if it is not controlled properly. However, using a fungicide like BASF’s Revystar can help control scald and improving yield. Revystar provides superior control against diseases, including scald, and promotes extra green leaf retention which can help maximize crop yields.

• What fungicide can I use for barley?

  BASF’s Revystar fungicide is an excellent choice for barley. It offers outstanding control of diseases such as Ramularia leaf and awn spot, brown rust, and scald, ensuring better yield and healthier crops.

• What is the active ingredient in Revystar?

• What stage do you spray barley?

  The best application timing for BASF’s Revystar on barley is T2: typically 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.
