To evaluate the cost effectiveness of strobilurin based fungicides on barley in the different climatic regions of southern Australia.
In a barley trial where the principal diseases were leaf rust (Puccinia hordei) and powdery mildew (Blumeria graminis), foliar fungicide application increased yield by between 0.36 – 1.75 t/ha, taking the untreated yield from 2.79 t/ha to a maximum of 4.54 t/ha.
