In this podcast, Professor Robert Park, University of Sydney, talks about rusts and managing rusts with fungicides. Until now, there have been very few cases of resistance to fungicide in rusts. However, recent research has shown insensitivity in the barley and wheat leaf rust pathogens to Group 3 DMI fungicides. At this stage, there have been no known in-field failures of fungicides for rust but this does represent a shift.

As Professor Park points out, the foundation of controlling rusts in crops needs to be based on genetics and selecting varieties with high levels of genetic resistance. The other elements of the Fungicide Resistance Five – crop rotation, non-chemical control methods, strategic spraying and rotating fungicide modes of action – are also important when controlling rusts.
