Treatment rate:  Once case treats 160 acres for fusarium head blight (119 mL/ac.) and 210 acres for leaf diseases (89 mL/ac.)
Crop staging:  Fusarium head blight from 75% head emergence to 50% flower, leaf diseases from the 4-leaf to early flag leaf

Registered crops

  • Barley

Diseases controlled

  • Fusarium head blight (suppression)
  • Rusts – leaf, stem and stripe
    (Puccinia triticina, P. graminis, P. striiformis)
  • Septoria – leaf blotch (Septoria tritici)
  • Tan spot (Pyrenophora tritici-repentis)
  • Net blotch (Pyrenophora teres)

  • Crown rust, oat (Puccinia coronata)
  • Septoria glume blotch

Disease Control Challenge

Cereal growers are constantly faced with the threat of fusarium head blight and rusts – two of the most yield damaging diseases to cereal crops. Half of spring wheat and two thirds of durum sampled in 2016 contained fusarium damage* and rusts are growing in prevalence with stripe (yellow) rust able to successfully overwinter in Western Canada. These diseases can both have a devastating impact on wheat yield and quality.

Nufarm Solution

Hornet fungicide delivers another option to help growers defend their cereal crops against damages from fusarium head blight and rusts. Hornet (Group 3) is a proprietary brand of tebuconazole in a liquid formation, similar to Folicur®, providing Canadian farmers access to another tool to protect their cereal crops from two serious diseases.


  • New alternative tebuconazole foliar fungicide
  • Fusarium head blight suppression in cereal crops
  • World’s leading rust control


  • Control of stripe rust which is a growing issue for Canadian farmers that has now been found to overwinter in some of geographies
  • One solution plus many different timings and diseases, can be used from 4-leaf to flowering depending on the disease targeted
  • Crown and stem rust control in oats
  • Coverage, coverage, coverage

Performance Tips

  • Timing is critical to apply prior to disease development when heat and humidity are conducive
    to infections

For fusarium head blight

  • Optimum coverage of the head is required
  • Recommended use of a non-ionic surfactant such as Carrier when sprayed alone for best results
  • Apply from the time 75% of the main heads have emerged up to 50% flowering of the main heads

For leaf disease

  • Apply at the first signs of disease development
  • Best yield results when the flag leaf is protected
